Topalov vence Bilbao 2008 com grande folga!

 

13.09.2008 – Veselin Topalov venceu seu jogo final contra Vassily Ivanchuk, assegurou o primeiro lugar por uma grande margem [4 pontos] e avançou ao #1 no não-oficial “Live Ratings” do mundo do xadrez. Teimour Radjabov venceu seu derradeiro [e foi a única vitória do jovem de 21 anos] desafio e com as pretas, contra o sempre perigoso Levon Aronian, o que assegurou o segundo lugar a Magnus Carlsen [de acordo com o sistema de Bilbao]. Anand foi — incrível! — o último colocado [fazendo-nos todos pensar se será adversário duro para o “senhor dos matches” Vld. Kramnik…].

 

 

 

No unofficial Live Ratings Veselin Topalov é agora o 1º do mundo, seguido de Alexander Morozevich, Magnus Carlsen e Vassily Ivanchuk. Vishy Anand caiu ao 5º lugar, sete pontos atrás do líder e onze adiante de Vladmir Kramnik, seguido [quinze pontos depois] de Levon Aronian.

E será o novo # 1 do mundo na lista oficial da FIDE [a ser publicada em 1º de outubro deste 2008]!

Já havia eu predito que este torneio poderia premiar os jogadores ousados [vez que a vitória equivalia a +3 e o empate a apenas +1] e o augúrio se mostrou verdadeiro, já que Topalov ficou em primeiro e Carlsen em segundo; quem foi cauteloso, voltou p’ra casa daí p’ra trás, longe do topo. Uma beleza…

Vejamos o repertório de aberturas/defesas utilizadas por “Vesco”, ao longo do torneio:

  • Round 1 — C45. De pretas, entrou por uma Ruy Lopez contra Radjabov, inovando totalmente no lance 8. …a5, nunca jogado no nível dos GMs. A partida terminou em empate.
  • R2 — D12. De brancas, entrou com um Gâmbito da Dama, contra Aronian, também inovando no início [lance 7] e forçando o oponente a perder dois tempos de abertura. Jogo empatado.
  • R3 — D58. Contra Carlsen, foi de Defesa Francesa, inovando muito no lance 14 e tomando muito tempo de Carlsen, que terminou por cometer um erro e perder o jogo.
  • R4 — E15. Contra Anand, optou pela Catalã, sacrificou um peão no lance 7 e adotou uma linha incomum, com o lance 11. Trouxe uma impressionante novidade no lance 12 seguinte e dominou Anand, fazendo-o resignar-se no lance 25!!! Impressionante vitória sobre o #1 e atual Campeão Mundial de Xadrez.
  • R5 — De pretas, contra Ivanchuk, adotou uma linha incomum da Defesa Nimzo-Indian, em que as damas são trocadas em f5, tornando tudo muito parecido com a defesa Muro de Berlin. O jogo findou-se empatado.
  • R6 — E74. De brancas, optou por 1.d4 Cf6 2.c4 g6 3.Cc3 Ag7 4.e4 d6 contra Radjabov, mas o que parecia uma Índia do Rei foi transposta numa Benoni [em que Topalov é grande especialista, em ambas as cores], com 5.Ag5 0-0 6.Ae2 c5 7.d5 a6 8.a4 h6 9.Ae3 e6 10.Cf3 exd5 11.cxd5. A posição era bastante promissora, mas uma imprecisão no lance 31 fez o jogo ficar igual e terminar em empate.
  • R7 — E36. De pretas, perdeu de Aronian com uma Nimzo-Indian.
  • R8 — B78. De brancas, venceu [novamente] a Magnus Carlsen, numa Siciliana/Dragão [com a variação que Carlsen quase sempre usa, contra GMs de alto nível: 12. …a6.
  • R9 — B18. De pretas, empatou com Anand servindo-se de uma tradicional Defesa Caro-Khan.
  • R10 — D46. Servindo-se do Gâmbito da Dama [contra a Defesa Semi-Eslava], derrotou Ivanchuk, no jogo que valia o primeiro lugar do torneio [embora os outros jogos também o pudessem valer, graças à pontuação de vitória ser +3], inovando a teoria no lance 12. Vencedor do Torneio!

1-0

Topalov and Anand are marching through in Morelia. The Bulgarian is leading with 2.5 points out of three (3000+ Elo performance!), the world champion has half a point less. Together they scored four wins so far. No one else has a plus score after the first three rounds.

Topalov,V (2780) – Ivanchuk,V (2751) [B90]
XXV SuperGM Morelia/Linares MEX/ESP (3), 17.02.2008

Another impressive victory for the ex-world champion. Just like in the first round win against Aronian, Topalov used opponent’s few inaccuracies in the opening to take over the initiative, after which at no point of the game there were any doubts left about the final result. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6








Ivanchuk chooses the always combative Najdorf Variation, which used to be Kasparov’s preferred weapon against 1.e4. It is curious that in the last game before his retirement from active chess (March 2005), Kasparov facing Topalov didn’t go for his favourite variation, deciding to play 2…Nc6 instead. 6.Be3 e5 7.Nb3 Be6 8.f3 Nbd7. Earlier this year Topalov himself preferred to prevent the advance of White’s g-pawn: 8…h5 9.Nd5 (9.Qd2 Nbd7 10.a4 Be7 11.Be2 Qc7 12.0-0 0-0 Leko,P (2753)-Topalov,V (2780)/Wijk aan Zee 2008) 9…Bxd5 10.exd5 Nbd7 11.Qd2 g6 12.0-0-0 Nb6 13.Qa5 Bh6 14.Bxh6 Rxh6 15.Kb1 Anand,V (2799)-Topalov,V (2780)/Wijk aan Zee 2008. 9.g4 b5 10.g5 b4 11.Nd5 Nxd5 12.exd5 Bf5 13.Bd3 Bxd3 14.Qxd3 Be7 15.h4 a5. Taking into consideration that White is going to hide his king on the queenside, Black starts active actions there before castling short. But the move has a drawback too: it turns out that White is happy to play on the queenside.








The main continuation is 15…0-0 used among others by Kasparov and Anand. White continues 16.0-0-0 with a sharp game. 16.a3. This somewhat surprising decision is typical for the ex-world champion though: he doesn’t seem to care about finding a secure place for his king in the future. A quick initiative in order to put an immediate and concrete pressure on the opponent is more important for Topalov. The justification of 16.a3 is that White can quickly build pressure after opening the files on the queenside. 16…a4. Considering that White doesn’t have a safe king, Black should rather seek for counterplay by playing at some moment f7-f6. From this point of view preferable looks 16…0-0 17.axb4 axb4 18.Rxa8 Qxa8 after which most likely White must castle as well: 19.0-0 (19.Qb5?! Nc5 points out the weaknesses in white structure: the pawn d5 is hanging.) 19…f6 20.Qf5 Qe8 with a complete mess and chances for both sides. 17.Nd2 Rb8 18.axb4 Rxb4 19.Qa3








White can be happy: the queenside is open and Black must solve concrete problems. 19…Qb8. Ivanchuk protects the rook and attacks pawn b2 at the same time. But as mentioned before, opening the files on the queenside favours White. 19…Qa5 keeps an eye on a much more important pawn d5. A possible follow up is 20.c3 (20.c4? Rxc4 and the knight is pinned) 20…Rb8 21.c4 (after 21.Qxa4 Qxd5 White’s king will soon become more vulnerable than his black colleague) 21…Ra8 (the computer prefers 21…Rb4 but for a human is scary to pin the pieces like that. After 22.Qc3 threatening Nb3 22…Nc5 23.b3 0-0 24.Ke2 followed by Rhb1 White is slightly better) 22.b4 Qc7 23.h5 is again a position where any result is possible. 20.c3! Rxb2 21.Qxa4 Rb7 22.Ke2








Possibly Vassily underestimated White’s possibilities here. Topalov’s play is very simple: the rook from h1 comes to b1, the queen goes to c6 and the knight to c4. Due to White’s pressure and very active queen Black will have to exchange pieces, but the endgame will be difficult anyway. 22…Rc7. In a bad position all moves are bad. 22…0-0 23.Rhb1 Rc8 24.Rxb7 Qxb7 25.Qa7 with a clear advantage in endgame. 23.Rhb1 Qc8








The Ukrainian succeeded avoiding the exchange of rooks. The rook on c7 is very important for defense: it controls the seventh rank and the important c-file. White must find a way to exchange the rook c7. How to do it? Watch the next two elegant moves: 24.Bb6! Rb7. The alternative was to open another file: 24…Rxc3 25.Ne4 Rc4 (or 25…Rc2+ 26.Kd3!+- Rh2 27.Rc1 Qb8 28.Bc7 followed by the winning check on a8.) 26.Rc1! Rxc1 27.Rxc1 Qb8 28.Rc7 and White wins a piece. 25.Ba7








The rook cannot retreat to c7 again due to 26.Rb8. Which means that White achieves his plan. Which means that Black can’t avoid a bad endgame. Which means that is in deep troubles. 25…e4 Having understood the situation, Ivanchuk tries to get at least some squares for his pieces. But… see above the comment after Black’s 22nd move. 25…0-0 26.Rxb7 Qxb7 27.Qc6 Qc8 28.Rb1 followed by Rb7 is also hopeless. 26.fxe4 Rxb1 27.Rxb1 0-0 28.Qc6 Ne5 29.Qxc8 Rxc8 30.Rb8! Rxb8 31.Bxb8. Mission completed. A pawn up, poor king and bishop for Black, plus the fact that the knight e5 can be always challenged by White means that the rest is an easy technical matter for Topalov. 31…Kf8 32.Nf3 Ng6 33.c4 Ke8 34.e5 Kd7 35.Kd3 h6 36.exd6 Bxd6 37.Bxd6 Kxd6 38.gxh6 gxh6 39.Kd4 f6 40.c5+ Kd7 41.Ke4 h5 42.d6 Ke6 43.Nd4+ Kd7 44.Nf5 Ne5 45.Kd5 Nc6 46.Nd4. In the past two years everybody got used to the fact that Topalov starts tournaments badly and finishes them in force. Unfortunately, this highly intriguing, but at the same time risky “strategy” can’t last forever, as the Corus tournament showed recently. It is great to see that in Morelia Topalov found a good form right from the start. After the World Championship in 2005 Topalov never started a tournament so strongly again. However, the temptation to make a parallel with the San Luis tournament will have to wait. In Argentina scoring 2,5 points out of three was just a prelude for the future world champion, who in the next rounds produced four consecutive wins. So let’s wait a little bit to see if in Morelia Topalov will continue in the same impressive fashion. 1-0. [Click to replay]


Carlsen,M (2733) – Anand,V (2799) [D43]
XXV SuperGM Morelia/Linares MEX/ESP (3), 17.02.2008

Carlsen fell a victim of his rather superficial opening preparation. Against the razor-sharp Anti-Moscow Variation he chose a rare line, but soon found himself in troubles with white. 1.d4. A month ago in Wijk aan Zee Carlsen started his game versus Anand with the kings’s pawn. In spite of getting a very promising position, the Norwegian lost that important game. This time he switches to a different opening. 1…d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 h6 6.Bh4 dxc4 7.e4 g5 8.Bg3 b5








9.Ne5. The main theory starts with 9.Be2 followed by oceans of variations which you don’t want to know. 9…h5. White released pressure on g5, so Black immediately advances the h-pawn. This is known to be the best reaction to 9.Ne5. Did Carlsen really hope that Anand will repeat moves from his rapid game? 9…Bg7 10.h4 Nfd7 11.hxg5 hxg5 12.Rxh8+ Bxh8 13.Qh5 Bxe5 14.Bxe5 Nxe5 15.Qh8+ Kd7 16.Qxe5 Bb7 17.0-0-0 Kc8 18.Qg7 Qe7 19.e5 Nd7 20.Ne4 Kc7 21.Nd6 Rf8 22.Be2 Kasimdzhanov,R (2683)-Anand,V (2792)/Mainz 2007. Black is still under pressure, but Anand managed to survive. White has numerous ways to improve, so expectedly the world champion goes for the strongest 9…h5 istead of 9…Bg7. 10.f3. After 10.h3 Black has a pleasant choice between 10…b4 and then taking pawn e4, or the normal continuation 10…Bb7.; Also 10.h4 g4 11.Be2 might be the best, when 11…Bb7 leads to the main lines, which start usually with the move 9.Be2. Playing main lines was clearly not Carlsen’s intention. 10…h4 11.Bf2 Bb7








12.Be2. A new move. Difficult to say what went wrong in Carlsen’s preparation: the resulting positions are good for Black. 12.Be3 Nfd7 13.Nxd7 Nxd7 14.Qd2 Be7 is known as advantage for Black. 12…Nbd7 13.Nxd7 Nxd7 14.0-0 e5!








Anand feels very well the Anti-Moscow Variation. This opening brought him many important points lately and there are little doubts that he continuously analyzes it. The diagram position certainly offers chances for White as well – in such situations White is usually justified to claim compensation for the pawn – but practical experience and feeling of the position are the decisive factors. Carlsen simply stepped on the opponent’s territory unprepared. 15.a4 a6 16.d5 Rh6 17.dxc6 Bxc6








Black has everything protected and he is a pawn up. Does Black have bad pieces? The king? Well, it is interesting to see how White is going to attack black king. In fact Black has a large advantage already. There are openings when if something goes wrong for White, then he can still hold equality easily (say Queen’s Gambit). But there are openings when if things go wrong, you can go home. Playing the Anti-Moscow with either colour is a risky business. 18.axb5 axb5 19.Rxa8 Qxa8 20.Qc1 Rg6 21.Rd1 Bc5 22.Bxc5 Nxc5 23.Qe3 Nb3 24.Qb6 Nd4








25.Rxd4 Carlsen fights bravely, but this cannot change the result. Anand firmly converts his material advantage. 25…exd4 26.Nxb5 Bxb5 27.Qxb5+ Qc6 28.Qe5+ Re6 29.Qxd4 Qb6 30.Qxb6 Rxb6 31.Bxc4 Rxb2 32.g3 f6 33.Be6 Ke7 34.Bg4 Re2 35.gxh4 gxh4 36.h3 Kd6 37.Kf1 Rb2 38.f4 Kc5 39.e5 Rb4 40.exf6 Rxf4+ 41.Ke2 Kd4 42.Bf3 Rxf6








43.Bb7 Rb6 44.Bc8 Ke4 45.Bg4 Rb2+ 46.Ke1 Ke3 47.Kf1 Kf4 48.Ke1 Kg3 49.Kf1 Rf2+ 50.Ke1 Rf4 51.Bc8 Rf8 52.Bg4 Kg2 53.Ke2 Re8+ 54.Kd3 Kf2 55.Bf5 Re3+ 56.Kd4 Kf3 57.Bg4+ Kf4 58.Kd5 Re5+ 59.Kd4 Rg5 In spite of the long game, this was a relatively easy victory for Anand. 59…Rg5 60.Bc8 Rg8 61.Be6 (61.Bg4 Rxg4 62.hxg4 h3) 61…Rd8+ 62.Kc4 (or 62.Kc3 Rd6 63.Bg4 Rg6 64.Bd7 Rg7 65.Be6 Ke5 66.Bc4 Rg3+) 62…Rd6 63.Bg4 Rg6 64.Bd7 Rg7 65.Be6 Ke5 and the bishop is caught: 66.Bg4 Rxg4+ 67.hxg4 h3. 0-1.

Topalov ganha, com outra de suas “invenções”!

Amigos[as], Veselin Topalov continua aprontando das suas e mostrando que ainda vai dar muito trabalho aos “top of the top” líderes do xadrez [assim como ele próprio, não?]. Desta vez, a vítima foi Levon Aronian, pela 1ª rodada do 1º turno do super-torneio de Morelia/Linares. Vejam a partida, abaixo [no final, tem link p’ra vê-la em pgn-reader]. Abraços a todos.

Morelia R1: GM Dorian Rogozenko annotates
17.02.2008 – The starting round in Morelia provided three decided games out of four. Topalov and Leko won with the white pieces against Aronian and Radjabov respectively, while Anand scored a win with black against Shirov. “Let’s hope that ‘the return of the Sicilian’ will remain the trend of this extremely strong tournament,” says our GM commentator Dorian Rogozenko, in his analysis of round one.

Morelia-Linares 2008

Round one commentary by GM Dorian Rogozenko

The starting round in Morelia provided three decided games out of four. Topalov and Leko won with the white pieces against Aronian and Radjabov respectively, while Anand scored a win with black against Shirov. Carlsen-Ivanchuk was the only draw. Let’s hope that “the return of the Sicilian” will remain the trend of this extremely strong tournament.


Topalov,V (2780) – Aronian,L (2739) [E20]
XXV SuperGM Morelia/Linares MEX/ESP (1), 15.02.2008

Topalov and Aronian met last time in the second round of Wijk aan Zee tournament (January 2008). In that game Topalov achieved advantage with Black, but completely misplayed the position and lost. In the end Aronian shared first place, while Topalov made a minus score, finishing on the 9th place… 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Nf3








This system was prepared by Kasparov and very successfully implemented in his second match versus Karpov (Moscow 1985), which was a surprise at that time, since 4.Nf3 has been considered a harmless move until then. In the past decades the theory of 4.Nf3 developed a lot. Topalov and Aronian have a vaste experience with it with both colours. 4…c5 5.g3: The arising positions are often a sort of mixture between Nimzo, Catalan and English Opening. 5…cxd4 6.Nxd4 Ne4 7.Qd3 Bxc3+ 8.bxc3 Nc5 9.Qf3 d6 10.Bg2








A solid variation for Black, who has a better pawn structure as the compensation for opponent’s bishop pair. White’s task is to exert pressure on Black’s queenside and on the d-file, trying to open the position. 10…e5. The alternative 10…Nbd7 was met in practice of both Topalov and Aronian. They must have come to the conclusion that White’s chances are preferable after that. 11.Qe3! An important novelty in the well-known position. White’s idea is to retreat the knight to b3 with greater effect. 11.Nb3 Nba6 12.Ba3 Qc7 13.Rd1 Be6 14.Bxc5 Nxc5 15.Nxc5 dxc5 (Better looks 15…Qxc5 16.Qxb7 Rc8 and Black must achieve a draw rather easily) 16.0-0 Rb8 17.Qh5 0-0 18.Bd5 Rfe8 19.Bxe6 Rxe6 20.Rd5 Re7 21.Rfd1 and Aronian squized a full point in Aronian,L (2756)-Nielsen,P (2646)/Turin 2006. 11…0-0. In case of 11…Nba6 Black must reckon first of all with 12.f4; 11…Qc7? 12.Nb5 Qb6 13.Ba3 Nba6 (or 13…0-0 14.Nxd6) 14.Rd1 winning. 12.Nb3 Qc7. Possibly this is already inaccurate. Critical is 12…Nba6 13.Ba3 Qc7. 13.Nxc5 dxc5. The endgame after 13…Qxc5 14.Qxc5 dxc5 15.Be3 is unpleasant for Black. 14.0-0 Nd7








15.f4! The right position for Topalov: White has the initiative and enough resources to exert pressure on opponent. Considering that in opposite to Aronian the Bulgarian must have analyzed the position at home, it becomes clear that Levon’s task was exceptionally difficult. 15…exf4. During the next few moves the position will become from good to almost winning for White, so around here Black should look for improvements. 16.Rxf4 a5. Very creative: the rook will enter the game via a6. Unfortunately for Aronian, this does not solve Black’s problems. 17.Qe7 Qe5 18.Qxe5 Nxe5 19.Be3 Nd7








20.Re4! The rook goes to e7 and it becomes clear that White’s advantage should be decisive. 20…Ra6 21.Rb1 Rg6 22.Re7 b6 23.Bf4








A complete domination of white pieces. On top of all Aronian was already experiencing problems with the time on the clock, so the rest was a technical matter for the ex-World Champion. 23…h5 24.Be4 Re6 25.Rxe6 fxe6 26.Bd6 Rf6 27.Rd1 Kf7 28.Bf4 Kg8 29.Bc7 Rf7 30.Bg6 a4 31.Bxh5 Nf6 32.Bxf7+ Kxf7 33.Bxb6 Ba6 34.Bxc5 e5 35.a3 Bxc4 A very “clean” and important win for Topalov. 1-0.

Magnus Carlsen [17 anos] recusa empate e derrota Kramnik!

Amigos[as], depois de Topalov, agora foi o jovem-prodígio Magnus Carlsen quem derroutou o “super-confiante” [e destronado…] Vladimir Kramnik, numa aula de final de torres/cavalo.

No alnce 30, Kramnik ofereceu empate; Carlsen recusou!

Massive interest for the game Kramnik vs Carlsen

Kramnik,V (2799) – Carlsen,M (2733) [A30]
Corus A Wijk aan Zee NED (12), 26.01.2008
1.Nf3 Nf6 2.c4 e6 3.Nc3 c5 4.g3 b6 5.Bg2 Bb7 6.0-0 Be7 7.d4 cxd4 8.Qxd4 d6 9.Rd1 a6 10.Ng5 Bxg2 11.Kxg2 Nc6 12.Qf4 0-0 13.Nce4 Ne8 14.b3 Ra7 15.Bb2 Rd7 16.Rac1 Nc7 17.Nf3 f5 18.Nc3 g5. Carlsen has played the Hedgehog and held his opponent thoughout a phase of manoeuvering. He now plays this interesting plan. 19.Qd2 g4 20.Ne1 Bg5 21.e3 Rff7 22.Kg1 Ne8 23.Ne2 Nf6 24.Nf4 Qe8 25.Qc3 Rg7 26.b4 Ne4 27.Qb3 Rge7 28.Qa4 Ne5

Kramnik may have had a slight edge, but the following pawn grab plan is based on a simple miscalcualtion, having missed that he could not take on b6 because of material loss. 29.Qxa6 Ra7 30.Qb5. Forced. After this the ending was very bad for White and Carlsen wrapped things up. 30…Qxb5 31.cxb5 Rxa2 32.Rc8+ Kf7 33.Nfd3 Bf6 34.Nxe5+ dxe5 35.Rc2 Rea7 36.Kg2 Ng5 37.Rd6 e4 38.Bxf6 Kxf6 39.Kf1 Ra1 40.Ke2 Rb1 41.Rd1 Rxb4 42.Ng2 Rxb5 43.Nf4 Rc5 44.Rb2 b5 45.Kf1 Rac7 46.Rbb1 Rb7 47.Rb4 Rc4 48.Rb2 b4 49.Rdb1 Nf3 50.Kg2 Rd7 51.h3 e5 52.Ne2 Rd2 53.hxg4 fxg4 54.Rxd2 Nxd2 55.Rb2 Nf3 56.Kf1 b3 57.Kg2 Rc2 0-1.

Wijk ann Zee, round 9: the tournament spectacular
23.01.2008 – Topalov vs Kramnik in round nine was pure spectacle, with a stunning novelty which had been kept a secret for three years, complicated middlegame fight and mutual missed opportunities. And with a kibitzing Garry Kasparov offering special insights. Adams gradually squeezed van Wely in a static position, managed to win a pawn with a simple trick and then the game.

The 9th round scheduled one of the most awaited game of the tournament, one that opposed the ex World Champions Topalov and Kramnik. The game was pure spectacle, with a stunning novelty which had been kept a secret for three years, complicated middlegame fight and mutual missed opportunities in the final part. Topalov won after 45 moves and there seems to have been just one moment when Kramnik could have saved the game.

Leko-Carlsen featured a tense fight with some initiative for White. Black defended actively, but then missed a relatively simple draw and immediately resigned (see the express report).

Playing with white, Adams gradually squeezed van Wely in a static position. He managed to win a pawn with a simple trick. Black was forced to launch an energetic counterplay, but eventually misplaced his pieces and, confronted with additional losses of material, resigned on move 47.

A spectacular tactical fight could be seen in Ivanchuk-Mamedyarov. The exchange of blows eventually resulted into almost complete simplifications and a logical draw.

Playing with Black against Judit Polgar, Radjabov unearthed the out-fashioned Jänisch Attack and obtained an entirely adequate position out of the opening. Soon, Judit initiated a tcaticaloperation resulting into a draw by perpetual check.

Anand once again employed his “pet” variation against Gelfand’s Catalan and equalized comfortably. In fact, Black’sposition looked more attractive after 25 moves, when a draw was agreed.

A solid but complex line of the English Opening was rehearsed in Aronian-Eljanov. Players ageed on a draw after 20 moves, in a moment when there was a lot of play yet.


Topalov,V (2780) – Kramnik,V (2799) [D43]
Corus A Wijk aan Zee NED (9), 22.01.2008 [Mihail Marin]

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6. During the Elista match, Kramnik played 4…dxc4 in all the 3 games where this position arised, obtaining entirely satisfactory positions out of the opening. After the match, he started employing the sharper Moscow/Anti-Moscow systems, where he seems to feel at home with both colours. 5.Bg5 h6 6.Bh4. Between players that do not shake eachother’s hands before the game, the positional 6.Bxf6 is out of question, of course. 6…dxc4 7.e4 g5 8.Bg3 b5 9.Be2 Bb7 10.0-0 Nbd7 11.Ne5 Bg7








This position is so frequently seen nowadays that it would hardly deserve a diagram under normal circumstances. The real tabyias arise slightly later, but in the present game White deviated from the approved path abruptly. 12.Nxf7!? If such surprises, in the true spyrit of the King’s Gambit, can arise from once in a while still, we are quite far from the exhaustion of our favourite game still. In the press conference Topalov said Cheparinov found Nxf7 three years ago, and they have been saving and developing it ever since. A huge effort indeed, but the resulting positions cannot be analized properly without considerable investment of time. All engines would consider that Black is just winning in all the lines, which can be quite discouraging for the faint-hearted. Contrary to the almost unanimous opinion, the move is not a novelty, though. It had been played for the first time by the Romanian correspondemce player Miron Nacu two years ago, as Marius Ceteras (among others, captain of the Romanian Ladies Olympic correspondence team) kindly informed me. 12…Kxf7








Black is a full piece up and there is no obvious way for White to get at least part of his material back. However, the permanent exposure of the black king to White’s pieces’ attack justifies the sacrifice from abstract point of view. 13.e5. Only this move is new. Both correspondence games continued with 13.f4 (If we spoke about the King’s Gambit, this move is quite natural, even if played with a delay of more than 10 moves) 13…b4 (This looks suspicious. Later, Black tried to improve by evacuating the king from the centre with 13…Kg8 when after 14.e5 Nd5 15.Nxd5 cxd5 16.Bh5 White’s kingside pressure eventually proved sufficient for reaching a draw in Brodda-Zidu, ICCF 2007.) 14.f5 exf5 (There is no immediate refutation for 14…bxc3 15.fxe6+ Kxe6 , but the presence of the king in the centre would be a permanent source of worries.) 15.Bxc4+ Ke7 16.Rxf5 bxc3 17.bxc3 Rf8 18.h4 with strong initiative for the considerable material disadvantage, Nacu-Brodda, ICCF 2006. 13…Nd5 14.Ne4. The next phase of the game consists of natural developing moves, as if nothing extraordinary had happened. Quite logically so, because development should be the highest priority in the first phase of the game no matter what. 14…Ke7 15.Nd6 Qb6 16.Bg4 Raf8 17.Qc2








17…Qxd4. This is the first move after which engines switch their evaluation from better for Black (already not winning, though) to at least equal for White. Which does not mean anything really, it might just be a consequence of the horison effect. Kramnik’s move was probably dictated by the desire to establish some communication between the opposite wings (something that was possible only along the back rank until now). From the computer’s suggestions, I would consider 17…Rhg8 as logical, because it develops the last piece, anticipating the infiltration of the white queen at the same time. 18.Qg6 Qxg4 19.Qxg7+ Kd8 20.Nxb7+. Black’s material advance has been reduced to the minimum, but Kramnik probably relied on his stability on light squares as well as on the optical dispersion of White’s forces all over the board. The queen and the knight are placed on active positions, but they are not sustained by the rooks, restricted to back rank activity for the time being. At the same time, the g3-bishop is somewhat out of play. Its only function is to keep the essential e5-pawn protected. 20…Kc8








The king could not go to c7 because of Nc5, with an unpleasant pin. However, the relatively best king retreat to c8 is not without drawbacks either. White is not at all forced to hurry with the check on d6, when after …Kc7 Black would reach relative stability on the queenside. Taking advantage of the fact that the d7-knight is hanging, too, Topalov will leave his own knight on b7 for several moves, keeping Nd6+ in reserve. This is a typical way to increase the force of a determinedpiece. From b7, the knight controls the c5- and d8-squares, but also, indirectly, all the squares that can be reached from d6 in one move. After a premature knight jump to d6, the former area of influence would be lost. During the game, it is hard to foresee all the cases when a difference would be made by delaying the move Nd6+, but while this possibility will be available anyway, delaying it will (at least theoretically) restrict Black’s choices. 21.a4 b4 22.Rac1. Threatening Rxc4! Black has obvious problems maintaining the queenside closed. 22…c3 23.bxc3








23…b3!? Aiming to maintain the c-file closed. 23…Nxc3 would allow White to coordinate the action of most of his pieces with 24.h3! Qd4 (24…Qe2 would leave both e6- and b4-pawns undefended and White would immediately attack them with 25.Qe7!) 25.Rfd1! when Black would have to find a form of giving up the queen for (probbaly) insufficient compensation, since the natural line 25…Nxd1? 26.Nd6+ Kc7? (Black should capture on d6 already. The text move aims to keep the knight and the e6-pawn defended, which is essential in order to avoid decisive attack.) loses the queen for nothing to 27.Nb5+; In case of 23…bxc3 White has a wide choice, but I like 24.Rfd1 best, because it brings the last piece into play. The concrete threat is Rxd5 followed by Qe7 with a strong attack. 24.c4. After the recent structural modifications, Black’s central knight has lost stability. 24…Rfg8 Black cannot afford to open the d-file and has to start chasing the enemy queen. 25.Nd6+.He could still have waited for one more move. 25…Kc7 26.Qf7 Rf8








A first critical moment of the game. White cannot evacuate his queen starting with 27.Qg6? because of 27…Nf4! 28.Bxf4 Rhg8! followd by 29…gxf4 with a strong counterattack. Agreeing to the repetion of moves is out of question (they would have had to look into eachother’s eyes in order to fix the draw in that case, but this would have been almost as humiliating as shaking hands!) which means, using the method of elimination, that White has to create a threat at least as strong as …Rxf7. 27.cxd5!? Optically speaking, the most natural decision. It is easy to establish that White will get ample compensation for his queen; no complicate calculation is required. Objectively speaking, 27.h3! might be better, though. This move was suggested by Garry Kasparov, who was following the game informally (phoning and discussing with people in between) on a notebook without an engine! In fact, the first sequence of moves is not difficult to calculate and I assume that Topalov saw it, too: 27…Rxf7 28.hxg4 Nf4 (The only way to maintain the material disadvantage within acceptable limits) 29.Nxf7 Ne2+ 30.Kh2! (This move is natural and would be the instant choice of most players. I have awarded it with an exclaim because in a certain line it will be essential not to have the king on the back rank.) 30…Nxc1 31.Rxc1 Rb8








Analysis diagram

Players have reversed their parts and it is White who is a piece up now. However, with the bishop temporarily imprisonned on g3, the b-pawn, sustained by the rook and knight, seems to be very dangerous. Topalov must have evaluated this position as unclear, but further analysis proves that Kasparov’s intuition did not let him down. White is able to generate a powerful and somewhat unexpected counterplay on the opposite wing, developing by one tempo faster than Black’s simple plan. Here are some possible continuations (part of them provided by Kasparov himself, when confronted with a powerful chess engine by Frederic Friedel) 32.Rb1 Nc5 33.f4! Nxa4 (Black should not lose time. In case of an exchange on f4, the bishop will get into play just in time to keep Black’s counterplay under control) 34.fxg5 hxg5 35.Nxg5 b2 (35…Nc3 also leads to remarkable play after 36.Nxe6+ Kc8 . The only possible retreat on an apparently empty area of the board. After any other move, White would play Rxb3! Once again, the direct and indirect action of White’s knight keeps under control a bunch of important squares. 37.Rf1 b2 38.Nc5! Establishing a nice net around the enemy king. 38…b1Q 39.Rf8+ Kc7 40.e6+ Kb6 41.Rxb8+ Kxc5 42.Rxb1 Nxb1 43.e7 winning.) 36.Nxe6+ Kc8 (Again the only square. 36…Kd7 37.Nc5+! Nxc5 38.e6+ would lose the rook; while 36…Kb7 leaves Black without the threat …Nc3.) 37.g5 Nc3 Finally, Black has reached his optimal regroupment, but after 38.Rxb2 Rxb2 39.g6+- the pawn is unstoppable. 27…Rxf7 28.Rxc6+ Kb8 29.Nxf7








29…Re8?! This is the second critical moment and… Black’s only chance to save the game! Kramnik played his last move quickly, apparently without considering any alternative to removing the rook from the attacked square. By this moment, Kasparov felt somewhat frustrated by the fact that on the server nobody was suggesting 29…Qe2! , which he considered a way to hold the position. The basic idea is similar to that behind his previous suggestion, 27.h3. Instead of parrying the threat Nxh8, Black creates a stronger one! Indeed, in case the knight captures on h8, Black takes on f1 followed by …b2, with a likely draw by perpetual, because Wite’s pieces are not communicating with eachother. Here is a (not entirely forced) line confirming Kasparov’s evaluation: 30.Rc3 (After 30.Rcc1 Rc8! 31.Rb1 b2 White is too passive to claim an advantage.) 30…b2 31.Rb3+ Ka8 32.Nxh8 Nc5 33.Rb5 (The rook is instable along the b-file and will have to capture on b2 at some point. However, it is useful to distract from its actual square the knight before doing that. 33.Rxb2?! Qxb2 34.dxe6 Nxe6 allows Black consolidate on the kingside,, while his a-pawn could prove dangerous in the near future.) 33…Nxa4 34.Rxb2 Qxb2 35.dxe6 Qb6 36.e7 Qe6 Apparently, White is in some trouble, but he can maintain some initiative with 37.f4 gxf4 (Otherwise, Black would have to fight against two connected pawns) 38.Bh4, but the position remains fairly unclear. 30.Nd6 Rh8 31.Rc4 Qe2 32.dxe6 Nb6 33.Rb4








White has a material advantage already, active piece placement, far advanced pawns and the safer position of the king. Black is in big trouble. 33…Ka8 34.e7?! More accurate would have been 34.Rxb3, keeping both e-pawns on board. 34…Nd5 35.Rxb3 Nxe7 36.Rfb1 Nd5 37.h3








There seems to be some hope for Black now, since there is no obvious way for White to improve his position. 37…h5?! But after this pseudo-active move, weakening the g5-pawn and allowing White regroup with gain of time, simplifies White’s task. 38.Nf7 Rc8 39.e6 Threatening mate in one. 39…a6 40.Nxg5 h4 41.Bd6! The h4-pawn has little significance in this moment. Topalov prefers to use his bishop to sustain the advance of his passed pawn. 41…Rg8 42.R3b2 Qd3 43.e7 Nf6 44.Be5 Nd7 45.Ne6








There is no satisfactory defence against Nc7+ followed by Rb7#. 1-0. [Click to replay]

______________

Round two commentary by GM Mihail Marin

The second round was characterized by intense fight on practically all boards. True, we saw only two decisive games (compared with three in the inaugural day), but the move average increased dramatically.


O armênio Levon Aronian lidera o torneio, com 2 em 2.

Gelfand-Aronian featured a complex strategic fight in which the telling factor was the exposed position of the white king. After blundering in a difficult position, Gelfand resigned on move 30.

Carlsen played a great technical game against Eljanov. The young prodigee gradually (and patiently!) increased his pressure until Black’s weakneses became impossible to defend.


Magnus Carlsen vs Pavel Eljanov resulted in a second victory for the Norwegian GM

In Kramnik-Radjabov and Leko-Adams, White had an extra-pawn in basically drawn positions. In both games, Black defended carefully and a draw was agreed after 98 (!) and 79 moves, respectively.

Once again, Topalov faced an interesting psychological situation, when Ivanchuk chose the Benoni, which used to be one of the Ex-Champion’s favourite surprise weapons. The game took an independent course rather soon, but ended in a draw by repetition after 30 moves.


Kramnik novamente empatou, com as brancas…

White obtained promissing positions in Van Wely-Polgar and Anand-Mamedyarov. In both games, Black defended actively, helped by the exposed position of the white king and managed to reach a draw.

Gelfand,B (2737) – Aronian,L (2739) [D15]
Corus A Wijk aan Zee NED (2), 13.01.2008 [Mihail Marin]

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3 a6 5.Nc3 b5 6.c5








6…Nbd7. The initial idea of the Slav Defence was to maintain the possibility of developing the light-squared bishop “outside” the own chain of pawns. Here, 6…Bg4 has been frequently played, but the absence of the bishop from the queenside can lead to white initiative after a4, with the permanent threat of a piece sacrifice on b5, resulting in a pair of connected passed pawns. Aronian prefers to delay the bishop’s development and carry out a thematic pawn break himself. 7.Bd3 e5 8.Nxe5 Nxe5 9.dxe5 Ng4 10.f4 Bxc5 11.Qf3 Qb6








12.Ke2. Steinitz would be proud of this move. The first World Champion tried to prove in his own games (and sometimes on his own skin) that the king can be an active and useful piece in the middlegame, too, not only in the endgame. For while, things will seem to work perfectly well for White in the present game, but later the exposed king’s position will become an increasingly irritating problem. 12…Nh6 13.h3 Nf5 14.g4 Ne7 15.Bd2 0-0








White is better developed and has an advantage of space in the centre. However, he cannot open play to soon, because this would leave His Majesty exposed to simple attacks. Besides, his central structure is not flexible enough to allow launching a kingside attack. 16.Rac1. White could have prevented Black’s next move with 16.f5, but the weakness of the e5-pawn would allow Black obtain counterplay with 16…Qc7 17.Qf4 Ba7 18.Rac1 (Threatening f6 followed by Nxd5) 18…Rd8! (Parrying the threat and intending to open play in the centre with …d4.) 16…f6! Played in accordance with Nimzowitsch’ theories. Any unpromoted pawn majority (or mobile formation) should be submitted to attacks. 17.exf6 Rxf6








White has a backwatd pawn on the e-file. His next move is correct from strategic point of view, because it eliminates the potential weakness, but puts the king in a dangerous situation. 18.e4 Bd4 19.exd5 cxd5 20.Kd1 Rf7 21.Re1 Bb7








Black has completed his development and has obtained some advantage of space himself. White’s king is relatively safe for the moment, but his presence in the centre somewhat hinders White’s coordination. Maybe it is early to claim an advantage for Black, but his play is easier to carry out anyway. 22.Qe2. The attempt to evacuate the king offers Black the initiative after 22.Kc2 Bxc3 23.Bxc3 d4 24.Qf2 Nd5 followed by either …Nb4+ or …Nxf4, depending on White’s answer. 22…Ng6 23.Bxg6 hxg6 24.Qe6 Rd8 25.Qxb6 Bxb6 26.Re6 Ba7








For the time being, the bishops’ placement looks modest, but after the unstoppable advance of the d-pawn they will exert devastating pressure against the white kingside. 27.Ne2 d4 28.Ng3 d3








29.Rxg6?? Overlooking the fact that the king is close to the zone of influence of the enemy bishops’, too. 29…Bf2! The knight cannot move because of …Bf3 mate. 30.Ba5 Bxg3. Threatening two consecutive checks on f3 and f4. 0-1. [Click to replay]


Carlsen,M (2733) – Eljanov,P (2692) [D91]
Corus A Wijk aan Zee NED (2), 13.01.2008 [Mihail Marin]

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Bg5. The systems based on Bg5 (with or without 4.Nf3) are a reasonable way to avoid long theoretical disputes while maintaining chances for a complex strategic fight. 5…Ne4 6.Bh4 Nxc3 7.bxc3 dxc4








8.Qa4+. This queen manoeuvre supposes considerable loss of time. However, after 8.e3 Be6 White might well not win the pawn back, while; 8.e4 would weaken the d4-pawn, which is quite significant once the bishop has been developed far from e3. Black would answer 8…c5 with excellent counterplay. 8…Qd7 9.Qxc4. White has obtained significant advantage in the centre, but the delay in development is not easy to eliminate after Black’s next move. 9…b6 10.e3 Ba6 11.Qb3 Bxf1 12.Kxf1 0-0 13.Ke2!








White continues his development by connecting rooks. For several reasons, his king is much better placed on this square than in the game Gelfand-Aronian: Black cannot open the position in the centre (the e-file basically) that easily; in case of emergency, the king can be easily evacuated with Kf1 (only after Rhd1, of course!); the position is somewhat simplified and in case of reaching an endgame (or queenless middlegame) the king belongs in the centre… 13…c5 14.dxc5 Na6! A typical Grünfeld move! Black is more interested in the c5-square than in the pawn itself. 15.Rhd1 Qb7 16.c6! The only way to fight for the initiative. After 16.cxb6?! Nc5 followed by …axb6, Black would activate his knight and queen’s rook with gain of time. The c3- and a2- pawns would be a permanent source of worry for White. 16…Qxc6 17.Bxe7 Rfe8 18.Ba3 Qxc3 19.Qxc3 Bxc3 20.Rac1 Bb4 21.Bb2 Bf8 22.Nd4 Nc5








The tactical phase has finished and time has come to draw some conclusions. Both sides have good development and excellent outposts for the knights. If this was an endgame, Black’s queenside majority would be a telling factor. However, the position looks more like a queenless middlegame and soon White’s kingside majority will become very threatening. It is important that he can advance his pawns without affecting the stability of the knight (which does not apply for Black, by the way). 23.g4 Re4 24.Kf3 Rae8 25.h3 f6 26.Ba3 Kf7 27.Rc2








27…Na6?! Black was under certain pressure, but his position was quite solid. His desire to simplify the position even more is understandable, but opening the c-file for an instant will allow White invade Black’s territory with all his remaining pieces. 28.Bxf8 Kxf8 29.Rc6 Kg7 30.Nb5 R4e7 31.Rdd6 Nc5 32.Nc7 Rf8 33.h4








A picturesque situation. White’s domination is almost complete. In the past, Petrosian and (slightly later) Karpov were great specialists of installing the own pieces on such advanced squares, right in the soul of the enemy position. 33…Rff7 34.Nd5 Rd7 35.Rxd7 Nxd7 36.Kg3 Nc5 37.f3 h6 38.Nf4 g5 39.Nh5+ Kg6 40.f4 gxf4+ 41.exf4 Kh7








The f6-pawn is indirectly defended because of the fork on e4, but in the long run its weakness will keep Black in absolute passivity. In the meanwhile, Carlsen will gradually improve his position, with the patiente of an experienced old player. 42.f5 Kg8 43.Kf3 Nd7 44.Ke4 Kf8 45.Rc8+ Ke7 46.Kd5








It can be felt that the end is near now. 46…b5 47.Rh8 Nb6+ 48.Kc6 Nc4 49.Ra8 Ne5+ 50.Kc5 Nd7+ 51.Kxb5 Kd6 52.Rxa7 Rf8 53.Kb4 Nc5 54.Kc4 Black has lost two pawns without solving any of his problems yet. Therefore… 1-0. [Click to replay]


Van Wely,L (2681) – Polgar,Ju (2707) [E21]
Corus A Wijk aan Zee NED (2), 13.01.2008 [Mihail Marin]

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Nf3 b6 5.Qb3 c5 6.Bg5 h6 7.Bh4 g5 8.Bg3 Ne4 9.e3 Bb7 10.Bd3 Nxg3 11.hxg3 g4 12.Ne5 d6 13.Nxg4 Bxg2 14.Rh2 Bf3 15.Be2 Bxg4 16.Bxg4 Nc6 17.Bf3 Qd7 18.0-0-0 Bxc3 19.Qxc3 0-0-0








From strategic point of view, the opening has been a success for White. He has the more compact structure, his bishop is more active than the black knight and his king seems to be in bigger safety than his colleague. Anticipating a bit, this latter aspect has a relative character… 20.Rdh1. Besides, Black cannot save his h-pawn. 20…cxd4!? 21.exd4 e5 There are several aspects that justify Black’s reaction. We all know that “an attack on the wing should be answered with a counterattack in the centre”. In order to avoid the undesired knight jump to d4, White will have to give up his bishop. This exchange will have two important consequences. First of all, Black’s king will feel much safer. Besides, several light squares from White’s camp will become vulnerable, leaving the white king slightly exposed. 22.Bxc6 Qxc6 23.d5 Qd7 24.Rxh6 Rxh6 25.Rxh6 Qg4








White has won the pawn, maintaining his structural integrity and the control of the only open file. In order to make further progress he has to secure his king, in order to avoid an eventual perpetual check. 26.b3! Consolidating the c4-pawn and preparing the evacuation of the king to… a3! 26…f5. The weakening of the seventh rank looks risky, but Black has to open a file for his pieces somehow. 27.Qe3 f4 28.gxf4








28…Rf8! The endgame would be hopeless for Black, of course. Now, an interesting tactical phase arises. 29.Rxd6?! It was hard to resist the temptation to capture this important pawn, but White loses an important tempo and temporarily spoils his coordination by cutting the rook’s communication with the queen. This is more than an resourcefull player like Judit needs to save the game. At first glance, 29.fxe5?? Qg1+ 30.Kb2 Rxf2+ 31.Ka3 would bring the king into safety, maintaining the material advantage. However, the unexpected discovered attack 31…Rxa2+! wins the queen for Black.; I believe that White should have not allowed to be distracted from his main plan, consisting of the evacuation of the king. After 29.Kb2!? Rxf4 (The endgame arising after 29…Qxf4 30.Qxf4 Rxf4 31.Rxd6 Rxf2+ 32.Ka3 e4 33.Re6 Re2 34.Kb4 looks pretty bad for Black.) 30.Ka3 Black’s initiative would have more or less vanished. White preserves his small material advantage and can think about initiating his own attack already. 29…Rxf4 30.Qg3. Here, too, 30.Kb2 comes into consideration. However, after the natural sequence 30…Qg2 31.Ka3 Rxf2 32.Kb4 Rxa2 33.Rh6








Analysis diagram

Black can carry out a similar plan starting with 33…Kb7! The position would remain sharp, with chances for both sides.

30…Qe2 31.Qh3+ Rg4! Black places her rook under a pin, in order to prevent the enemy queen from approaching the black king. With his army dispersed all over the board, White cannot avoid perpetual check. 32.f3 Qe1+ 33.Kc2 Qe2+ 34.Kc3 Qe3+ 35.Kc2 Qe2+ 36.Kc3 Qe3+ 37.Kc2 1/2-1/2. [Click to replay]

“Aula” de final de torres/peões.

Amigos[as], mais um encontro entre o tri e o penta campeões do nosso “Clube de Xadrez Criativo”: mais uma lapada no “MP Chewbaca”! A partida é muito instrutiva, no seu final de torres/peões. Inácio “Puro Osso” sacrifica um torre, para poder coroar um peão, terminando por conseguir duas promoções, sobrando uma dama; com ela, vence partida. Detalhe: a partida era com tempo de 1m./3s.!!! Boa leitura.

“Aula” de promoção de peão.

Negrada, dei uma lapada no MP. De quebra, em 3m./3s., dei a ele uma pequena aula de promoção de peão. Boa leitura.
