国际象棋超级大赛对局评注 2009年利纳莱斯超级大赛第一轮部分对局评注 (1) Anand,V (2791) - Radjabov,T (2761) [B33] XXVI SuperGM Linares ESP (1), 19.02.2009 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 gxf6 10.Nd5 Bg7 11.Bd3 Ne7 12.Nxe7 Qxe7 13.0-0 0-0 14.c4 f5 15.Qf3 d5 # In this complicated theoretical variation both players are the best specialists in the world - Anand for White, Radjabov for Black. The evaluation of this sharp position changed several times in the past 5-6 years. From big advantage for White to equality. In spite of its apparent aggressivity, Black is basically fighting only for a draw. 16.cxd5 fxe4 17.Bxe4 Rb8 18.Rfd1 f5 A surprise from Radjabov. Already five years ago in Linares Teimour was defending Black's side here. Against Topalov he played 18.. .Qh4, but didn't solve the problems. Then he found an improvement, 18...Qd7. His game against Vallejo went [ 18...Qd7 19.d6 Rb6 20.Qd3 Rd8 21.Rac1 Bf8 22.Qg3+ Bg7 23.Qd3 Bf8 24.Qg3+ Bg7 25.Qh4 Rxd6 26.Bxh7+ Kf8 and Black achieved sufficient compensation for the pawn, Vallejo-Radjabov, Linares 2004. After that the move 18...Qd7 became the main one for Black. However, White still keeps possibilities to improve and fight for advantage, for instance with 22.Rc7 instead of 22.Qg3+. In any case in the present game Radjabov didn't want to see the World Champion's preparation and decided to be the first one to deviate.] 19.d6 Qf6 20.Bc6 Be6 21.Bd5 Rbd8 22.Qb3 Bf7 [ 22...Bxd5 23.Rxd5 Kh8 24.Rad1 secured White a large advantage in Vehi Bach,V (2385)-Kosintseva,T (2479)/Kusadasi 2006.] 23.Nc2 Rxd6 24.Bxf7+ Rxf7 25.Rxd6 Qxd6 26.Ne3 f4 27.Rd1 Qg6 28.Nd5 # 28...Bf8 Only this move is a new one. [ In the game Bobras,P (2535)-Yakovich,Y (2583)/Port Erin 2006 Black won after having been lost on the way: 28...Kh8 29.Nc3 f3 30.g3 Qf5 31.Rd8+ Bf8 32.Nd1 Kg7 33.Ne3 Qg6 34.Qc3 White has a clear advantage. 34...Qb1+ 35.Rd1 Qe4 36.Rd5 Be7 37.h4 Bf6 38.Kh2 h5 39.Qc8 Be7 40.Qxa6 Bxh4 41.gxh4?? ( 41.Qe6 Bf6 42.Nf5+ Kg6 43.Nd6 wins for White) 41...Qxh4+ 42.Kg1 Kh7 43.Nf5 Rg7+ 44.Nxg7 Qg5+ and White got mated.] 29.f3 Kh8 Radjabov intends to use the g-file, but this brings Black nowhere. [ 29...Bc5+ 30.Kf1 Kg7 was more precise, with good chances to equalize. For instance: 31.Nc3 Bd4 32.Ne4 Rc7 and Black is okay.] 30.Nc3 Rg7? Following the initial plan. In fact Black just loses precious time: it will soon turn out that the white rook is better off on d2 than on d1. [ 30...Bc5+ 31.Kf1 Bd4 was called for, and if 32.Ne4 then 32...Rc7 ] 31.Rd2 Bc5+ 32.Kf1 Bd4 33.Ne4 Rc7 34.Rc2 This is the price for wasting time with the move 30...Rg7. The rooks exchange favours White. 34...Rc6 35.Qd3 Kg7 36.b3 h6 37.g4! Black's position is more difficult than it appears. After the inevitable exchange of rooks White will slowly prepare the attack. 37...fxg3 38.hxg3 Qe6 39.Kg2 Qc8 40.Rxc6 Qxc6 # A typical case when the Q+N dominates a Q+B. White has a clear plan to attack the opponent's king: g4 followed by Ng3. The next part of the game is very instructive. 41.Qd2 Qe6 [ After 41...h5 42.Qg5+ Qg6 43.Qe7+ Qf7 44.Qd6 Qg6 45.Qd7+ Qf7 46.Qc6 Qg6 47.Nd6 White wins material.] 42.g4 Qc6 Black has nothing better than wait for his destiny. The centralized bishop on d4 is completely out of play. 43.Ng3 Kh7 44.Nf5 Bb6 45.Qd3 Kh8 46.Qe2 Bc7 47.Qd2 Kh7 [ 47...e4 runs into mate after 48.Qd4+ ] 48.Ne7 Qc5 [ After 48...Qd6 49.Qc2+ Kh8 50.Nf5 Qb6 White must be careful to avoid 51.Nxh6? Qxh6 52.Qxc7 Qd2+ with a draw, but 51.Qe4 instead keeps the position winning.] 49.Qd3+ Kh8 50.Qd7 Finally White penetrates with both pieces, creating decisive threats. 50...e4 51.Qe8+ Kg7 52.Nf5+ Kf6 53.Qxe4 Bb6 54.Kh3 h5 # 55.g5+! Kxg5 56.Ne7 Kf6 57.Nd5+ Kg7 58.Qe5+ Kh6 59.Qf6+ Kh7 60.Qf7+ Kh6 61.Ne7 A very strong game by Anand. 1-0 (2) Aronian,L (2750) - Carlsen,M (2776) [E06] XXVI SuperGM Linares ESP (1), 19.02.2009 1.d4 Nf6 2.c4 e6 3.g3 d5 4.Nf3 Be7 5.Bg2 0-0 6.0-0 dxc4 7.Qc2 a6 8.Qxc4 b5 9.Qc2 Bb7 10.Bd2 Be4 11.Qc1 Bb7 # 12.a3 A rare continuation in a well-known theoretical position. Aronian, who by the way played this variation before with both colours, is preparing b2-b4, which fights against Black's main idea in this system: the advance 12.Bf4 a move played in the past also c7-c5. [ The most frequent continuation here is by Kasparov, or... Aronian himself.] 12...Qc8 13.b4 Nbd7 14.Bc3 A new move. 14.Bf4 ] 14...Ne4 15.Nbd2 Bd5 16.Qc2 Nxd2 17.Bxd2 Qb7 18.Rac1 Rac8 # White [ achieved his goal, but Carlsen reasonably considers that one single weakness (pawn c7) in his camp is easy to protect and therefore doesn't represent a real problem. 19.e4 [ After 19.Rfe1 Black can prevent e2-e4 with the radical 19...f5 ( or 19...Nf6, but not 19...Be4? in view of 20.Ng5 Bxc2 21.Bxb7 and in opposite to the game White has kept the e-pawn.) ] 19...Bxe4 20.Ng5 Bxc2 21.Bxb7 Bd3 22.Rfe1 Aronian offers his opponent the possibility to change his mind and instead of giving up the exchange to return the extra pawn. [ 22.Bxc8 Rxc8 23.Rfe1 Bc4 leads to the position from the game.] 22...Bc4! Carlsen follows his initial plan. [ Weaker is 22...Rb8 23.Rxc7 with advantage for White] 23.Bxc8 Bxg5! Just like on move 16, for Black is important to exchange enemy's knights. 24.Bxg5 Rxc8 # White won an exchange, but Black has a pawn for it and a very good control over light squares. In fact from the practical point of view the position is even easier to play with Black, since White doesn't even have targets for attack. After several more moves the players repeated the position and agreed to a draw: 25.f3 f6 26.Bf4 Nb6 27.h4 Kf7 28.Kf2 c6 29.Bd6 Bd5 30.Bc5 Na4 31.g4 Ra8 32.Re2 a5 33.Bd6 axb4 34.Bxb4 Nb6 35.Bc5 Na4 36.Bb4 Nb6 37.Bc5 1/2-1/2 (3) Dominguez Perez,L (2717) - Grischuk,A (2733) [C19] XXVI SuperGM Linares ESP (1), 19.02.2009 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.Qg4 cxd4 8.Qxg7 Rg8 9.Qxh7 Qc7 10.Ne2 Nbc6 11.f4 Bd7 12.Qd3 dxc3 13.Rb1 d4 14.Rg1 [ In November 2008 at the blitz World Championship Black achieved a nice position after 14.g3 0-0-0 15.Bg2 Na5 16.0-0 Bc6 17.Bxc6 Naxc6 although the Cuban Grandmaster won the game.] 14...0-0-0 # 15.g4 This move started to gain popularity after a game by Svidler in 2007. The idea behind 15. g4 is obvious: White takes away square f5 from opponent's knight. On the other hand such moves always produce weaknesses in one's own camp as well. [ After 15.Nxd4 Nxd4 16.Qxd4 Bb5 17.Qxa7 Bxf1 18.Kxf1 Qc6 the variations are analyzed until a forced draw!] 15...Nd5 [ In most games Black used to protect pawn d4 with 15...Be8 but Grischuk reasonably considers that Black is happy to open the position and therefore leaves the pawn on d4 unprotected. Indeed, if Black was ready to sacrifice it before, then why not do it again?] 16.Nxd4 Nxd4 17.Qxd4 Kb8 18.Rg3 Bc6 19.Qc5 f6 20.exf6 [ More interesting was 20.Be3 which would have kept chances for both sides. The idea is to answer 20...b6 with 21.Bd4! ] 20...Nxf6 21.Qe5 Nxg4 22.Qxc7+ Kxc7 Due to reduced material the draw is the most likely outcome in this slightly better endgame for Black. 23.f5 exf5 24.Bf4+ Kc8 25.Rxc3 Nf6 26.Rc4 # 26...Nd5 [ Here Grischuk missed some winning chances: 26...Rde8+! 27.Kd2 Ne4+ 28.Kc1 Rg4 ( 28...Rg1 brings nothing in view of 29.Kb2 ) 29.Be3 ( 29.Bd2? loses due to 29...Rg1 ; 29.Bg3 Nxg3 30.hxg3 Rxg3 is a big 29...Ng3! 30.hxg3 Rxe3 and White must looking for escape in advantage for Black) different kind of endgames with a pawn down.; Not 26...Rge8+ 27.Be2= ] 27.Rd1 Nxf4 28.Rxd8+ Kxd8 29.Rxf4 Be4 30.Bd3 1/2-1/2 2009年利纳莱斯超级大赛第二轮 (4) Carlsen,M (2776) - Dominguez Perez,L (2717) [A33] XXVI SuperGM Linares ESP (2), 20.02.2009 1.c4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.g3 Qb6 7.Ndb5 Ne5 8.Bf4 Nfg4 # 9.Qa4 This astonishing move was introduced into practice last year by Aronian, who surprised Leko in Morelia 2008. 9...g5 Faced with a new situation in the above-mentioned game this advance took Leko 80 minutes of thought. Dominguez spent less than a minute for it. His next moves were played a tempo as well - a clear sign of good home preparation. 10.Bxe5 Qxf2+ An important novelty! In the game Aronian-Leko, Morelia 2008 Black continued 10... Nxe5. 11.Kd1 Nxe5 12.Nc7+ Kd8 13.Nxa8 Qd4+ 14.Kc2 Nxc4 15.Kb3 [ Without preparation Carlsen wasn't ready to test the most principled continuation 15.e4 Qd2+ 16.Kb3 Qxb2+ ( 16...Ne3 loses: 17.a3 Qc2+ 18.Ka2 ) 17.Kxc4 d5+ and here White must find ( Not 17...Qxa1 18.Qa5+ b6 19.Qxg5+ Be7 20.Qe5 winning) 18.Kd3! ( 18.exd5 Bg7 favours Black) 18...Bg7 19.Ne2 # This wild position requires a careful analysis in order to tell if White can emerge out of complications with some advantage. At the first sight Black has sufficient counterplay to keep the balance. Here is a possible variation that ends up with a draw by perpetual check: 19...Bd7 ( worse is 19...dxe4+ 20.Ke3 Qxa1 21.Bg2 Qe5 22.Qxa7 Bd7 23.Rc1 ) 20.Qxa7 Qxa1 ( 20...Bb5+ 21.Ke3 d4+ 22.Kf2 is again winning for White) 21.Bg2 Bb5+ 22.Ke3 Qb2 23.Qb8+ Ke7 24.Qxb7+ Kf8 25.Qc8+ Ke7 26.Qc7+ Ke8 and White can either repeat the moves, or try to play for more with 27.Re1.] 15...Nd2+ 16.Kc2 Nc4 17.Kb3 Nd2+ 18.Kc2 1/2-1/2 (5) Anand,V (2791) - Aronian,L (2750) [D47] XXVI SuperGM Linares ESP (2), 20.02.2009 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.e3 Nbd7 6.Bd3 dxc4 7.Bxc4 b5 8.Bd3 Bd6 9.0-0 0-0 10.Qc2 Bb7 11.a3 [ 11.Ng5 ] 11...a6 12.Ng5 A positional pawn sacrifice, which has been played before with the pawns on a2/a7 (without the inclusion of moves 11.a3 a6). 12...Bxh2+ [ The merit of inclusion a3/a6 can be seen in the following variation. In case of 12...h6 13.Nge4 Nxe4 14.Nxe4 Be7 White can use the pawn on a3 by continuing 15.b4 with an edge] 13.Kxh2 Ng4+ 14.Kg1 Qxg5 15.f3 Ngf6 16.e4 Qh4 17.Be3 # For the sacrificed pawn White has a strong pawn center and the bishop pair. Besides, Black has problems with the coordination of his pieces. 17...e5 18.Ne2 Nh5 19.Qd2 Threatening to catch the black queen with 20.Bg5. 19...h6 20.Rfd1 Rae8 21.Bc2 Re6!? Very brave play from Aronian, who is not willing to defend a passive position and instead wants to create an attack on the kingside. Perhaps already here the Armenian foresaw the following piece sacrifice. 22.Bf2 Qe7 23.g4! The World Champion shouldn't be asked twice. Anand simply follows the strongest plan for White: g4 followed by Ng3-f5, increasing the space advantage on the kingside without being afraid of possible weaknesses, since Black's attacking potential is insufficient. 23...Rg6 24.Kf1 Nhf6 25.Ng3 # 25...Nxg4 A wise practical decision from Aronian. Objectively it doesn't change the evaluation: White will have a clear advantage after it, but suddenly Anand will have to solve defensive problems as well. [ 25...Qe6 26.Nf5 White gets what he wants: an easy play with great compensation for the pawn.] 26.fxg4 Qh4 [ Weaker is 26...Rxg4 27.Nf5 Qf6 28.Qc3 Re8 29.Qf3 Rf4 30.Qg3 with large advantage for White] 27.Nf5 Qxg4 28.Qc3 [ In spite of the fact that after 28.Ne7+ Kh7 29.Nxg6 fxg6 White remains with a rook up, the remaining black rook comfortably enters the game without having to make any moves.] 28...Re8 29.Qg3 Anand would be happy to exchange queens and thus completely neutralize opponent's threats against white king. Aronian obviously tries to avoid it. 29...Qh5 30.Qh4 Qf3 31.Rd3 Qg2+ 32.Ke2 exd4 # 33.Rg3?? The desire to exchange queens as quick as possible backfires. White has sufficient defensive resources and shouldn't have worried so much about his king on e2. [ After 33.Rxd4 Anand would have kept a large advantage, since White will start soon to create his own threats against black king. Besides, the queen on g2 is exposed and Black will have to exchange queens himself, which would lead to a very difficult endgame for him. In case of 33...Ne5 34.Rd8 Qf3+ 35.Ke1 Rxd8 ( or 35...Rge6 36.Nd4 ) 36.Qxd8+ Kh7 37.Ne7 Qh1+ 38.Kd2 Nc4+ 39.Kc3 Qh3+ 40.Bd3 it is Black who gets mated] 33...Rxg3 34.Qxg3? # [ 34.Nxg3 was called for, but Anand misses Black's answer.] 34...Rxe4+! It turns out that the rook cannot be taken due to the loss of knight f5. Thus with the last two moves White only lost his two central pawns. This is enough for Black to have a winning position now. 35.Kd2 Rg4! 36.Qxg2 Rxg2 37.Ke2 c5 Five pawns are just too much for the bishop. Black is completely winning. 38.Rg1 Ne5 39.Rxg2 Bxg2 40.Kd2 h5 41.b4 Nc4+ 42.Kc1 Nxa3 43.Bd1 cxb4 44.Bxh5 g6 45.Ne7+ Kf8 46.Nxg6+ fxg6 47.Bxg6 Ke7 48.Bxd4 Kd6 49.Bd3 Nc4 50.Bg7 a5 51.Be2 Be4 52.Bf6 a4 53.Bg7 Kd5 0-1 (6) Grischuk,A (2733) - Wang Yue (2739) [D17] XXVI SuperGM Linares ESP (2), 20.02.2009 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 Bf5 6.Ne5 Nbd7 7.Nxc4 Nb6 8.Ne5 a5 A pet line of several Chinese Grandmasters, who show a stable belief in their beloved opening variations by using them again and again. This approach has advantages and drawbacks. One gets to know one's own variation in deepest details, but on the other hand one should always be ready to face very well prepared opponents. 9.e3 g6 10.Bd3 Be6 [ More natural looks the move preferred by another Chinese GM - Bu Xiangzhi 10...Bxd3 Black achieves a solid position after it: 11.Nxd3 Bg7 12.0-0 0-0 13.Qe2 Nfd5 14.Rd1 Nb4 15.b3 N6d5 with equality, Adianto,U (2589)-Bu Xiangzhi (2671)/Doha 2006.] 11.0-0 [ Two month ago Grischuk prepared the advance of the e-pawn and won as well: 11.Be2 White needs this move in order to protect pawn d4. 13.Nf3 Bg4 14.0-0 0-0 15.h3 Bxf3 16.Bxf3 e5 17.d5 Re8 18.g3 11...Bg7 12.e4 Nfd7 Qe7 19.b3 Rad8 20.Be3 cxd5 21.Nxd5 Nxd5 22.Qxd5 b6 23.Qb5 Bf8 24.Rad1 Qb4 25.Be2 Nc5 26.Qxb4 axb4 27.Bc4 Kg7 28.Kg2 f6 29.Bd5 Rb8 30.Rc1 Na6 31.Rc6 Bc5 32.a5 Bxe3 33.fxe3 Nc5 34.axb6 Nd7 35.Rc7 Re7 36.Bc6 Rxb6 37.Rxd7 1-0 Grischuk,A (2719)-Wang Yue (2736)/Elista 2008] 11...Bg7 12.f4 Nfd7 This and the next move produce a strange impression - Black will remain with a broken pawn structure after it. 13.Nf3 c5 [ 13...h6 14.e4 is also hardly a solution for Black.; The best is 13...Bc4 but then the question is why hasn't Black exchange these bishops on move 10?] 14.Ng5! cxd4 15.Nxe6 fxe6 16.Ne4 # White has a nice compensation for the pawn: the better pawn formation and the bishop pair. 16...0-0 17.Qg4 Rf5 18.Qh3 Nc5 19.Nxc5 Rxc5 20.Qxe6+ Kh8 21.e4 Rac8 22.e5 R8c6 23.Qf7 Nd5 24.Bd2 Qf8 25.Qxf8+ Bxf8 26.Rac1 e6 27.Kf2 b6 28.Kf3 Kg7 29.g3 Rxc1 30.Rxc1 Rxc1 31.Bxc1 Kf7 32.Bc4 Ne3 33.b3 Bc5 34.Ke2 h5 35.Bb2 g5 [ A waiting strategy doesn't help either.

A somewhat unexpected decision. would transpose into the Gruenfeld Defence. It turns out that Aronian is looking for more than fight for a slight edge in the position arising after 6.Bg2 d5 7.cxd5 cxd5. 6...d5 7.cxd5 cxd5 8.e5 Ne4 9.Bg2 Nc6 10.0-0 Bg4 11.h3 Bxf3 12.Bxf3 Rc8 # 13.h4 This is a standard advance in such structures. White gains more space on the kingside and might launch an attack later on. Black is usually looking for counterplay on the opposite side. However, there is another idea behind the advance of the h-pawn. Somitemes Black can fight for the supremacy in the center by means of f7-f6. In that case the advance of the h-pawn will weaken the pawn g6, discouraging Black from the mentioned plan in the center. Although Black has no weaknesses, White's chances are slightly preferable first of all thanks to his space advantage. [ 13.Nxe4 dxe4 14.Bxe4 Qxd4 15.Bxc6 ( or 15.Qxd4 Nxd4 16.Bxb7 Rb8 followed by 17...Bxe5) 15...Qxd1 16.Rxd1 Rxc6 is equal] 13...Qa5 By increasing pressure on c3 Radjabov tries to force his opponent to take on e4, which would open for Black the d-file and considerably increase the influence of his bishop on the long diagonal. [ The standard method 13...Nxc3 14.bxc3 Na5 15.Qd3 doesn't fully solve Black's problems: White easily protects his only weakness on c3 and can concentrate on developing the attack on the kingside.] 14.Qd3 [ 14.Nxe4 dxe4 15.Bxe4 would be a mistake. After 15...Rfd8 Black will retain the pawn in a favourable situation - all his pieces will remain active.] 14...Rfd8 15.Be3 A clever move, provoking the following answer. [ The tactics 15.Nxd5 doesn't work: 15...Rxd5 16.Bxe4 Rxd4 and White will remain with a pawn down.] 15...Nb4 This leads Black nowhere, but it was not easy to create counterplay anyway. [ 15...f6 16.exf6 ] 16.Qe2 Nxc3 17.bxc3 # 17...Nc6 [ It turns out that after 17...Rxc3 18.Bd2 Black must sacrifice the exchange and although this is quite interesting, it is insufficient to equalise: 18...Nc6 ( 18...Ra3? 19.Rfb1 Ra4 20.a3 loses a piece) 19.Bxc3 Qxc3 20.Rac1!

It is no better than the other theoretical moves, 18.Be3 and 18.Bf4". Well, puzzled enough?
