2019年十佳棋局top10之第1局 弃后争先
chess.com网站评选出2019年度十佳棋局，今天欣赏top10里面的最后一个，No.1，由Firouzja 对 Karthikeyan 。这盘棋走到第9回合黑方就果断弃后，没有深谋远算的功力跟本走不出来，走出来也控制不了局势，最后的发展还好比较顺利，捍卫了年度第一棋局的地位。

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 {The King's Indian.} 5. h3!? {Firouzja
employs a side line.} 5... O-O 6. Be3 c5 7. Nf3 Qa5 8. Nd2!? {A relatively
unknown and new idea by the Iranian prodigy.} (8. Qd2 {and}) (8. Bd3 {were
White's main options}) 8... cxd4 9. Nb3 Qxc3+!! {After 21 minutes of thought,
Karthikeyan came up with this brilliant idea. Thinking purely in chess terms, I
like the fact that Black gets two minor pieces and a pawn for the sacrificed
queen, and apart from that wrecks White's pawn structure a little bit and gains
good sole control over the dark squares. But a queen is still a queen, and great
guts and imagination are required to sacrifice it!} 10. bxc3 dxe3 11. f3
{Ambitious but a bit risky too. White wants to keep his pawn structure intact
and hopes to encircle the e3-pawn in the long run. Alas, this does not happen in
the game, and the pawn on e3 turns out to be a thorn in White's flesh.} (11.
fxe3 Nxe4 {is good for Black.}) (11. Qc2 exf2+ 12. Qxf2 Nc6 {Black has two minor
pieces and a pawn for the sacrificed queen. But more importantly, White's weak
pawn structure, a slightly weakened king and the lack of control of dark squares
from White's point of view give Black excellent positional compensation for the
queen.}) (11. Bd3 {The computer's top choice} 11... exf2+ 12. Kxf2 {is
unclear.}) 11... Nh5! {Note the position of the pawn on h3 that weakens the
g3-square and also indirectly the f4-square. If the pawn were on h2, White could
have retained a good chance of control of the central dark squares with an
eventual g2-g3 and f3-f4. But Black obviously was attentive to this little
detail!} 12. Qc1 Bh6 13. g4 Nf4 14. Kd1 Ne6 (14... Nd3! {is a nice way to win
back the queen and maintain the initiative. But Murali clearly wasn't in the
mood for this.} 15. Bxd3 e2+ 16. Kxe2 Bxc1 17. Rhxc1 Na6 {with an edge.}) 15.
Kc2 Nc6 16. h4 {This threatens g5.} 16... Bf4 {Clearly things have become a
whole lot brighter from Black's perspective. He is completely dominating the
central and kingside dark squares, thanks to the absence of White's minor pieces
that could have controlled them. White's king is rather shaky in trying to find
a permanent shelter, while his pawns, especially the backward doubled pawns on
the semi-open c-file, are inviting targets for Black's pieces. Black has no
targets or weaknesses to offer to White's major pieces. Black's coordination of
all his pieces is remarkable!} 17. Qd1 Ne5 18. Nc1 Bd7 {Lurking with the threat
of Ba4+.} 19. a4 Rac8 20. Ne2 Bh6 21. g5 Bg7 22. Bh3 Nxf3 {Now Black has another
pawn and huge compensation for the queen.} 23. Qd3 Ne5 24. Qxe3 Nxc4 {Black
trades the e3-pawn for the c4-pawn as it opens another avenue for him. Black
soon plans to attack along the c-file and the c3-pawn.} 25. Qf2? (25. Qd3 {is
White's best continuation. But it's very hard to criticize White for his play.}
25... Rc5) (25. Qxa7 Bc6 26. Ng3 Ra8 27. Qf2 Bxa4+ {and White's position
collapses.}) 25... Rc5 26. Rhb1 {Probably the decisive mistake.} 26... Bc6 27.
Bg2 f5! {Each of Black's pieces is a symbol of efficiency. Now Black brings the
last dormant rook on f8 into the game and crashes through White's defense.} 28.
gxf6 Bxf6 29. Rf1 Bxc3 30. Qxc5 {Firouzja has had enough and gives up his queen
and material advantage in a desperate attempt for counter-chances.} 30... Nxc5
31. Rxf8+ Kxf8 32. Kxc3 Ne5 {This position is reminiscent of endgames from a
Sicilian Dragon where Black mops up all White's pawns, although he is an
exchange down.} 33. a5 Nxe4+ {Black is clearly winning now. Murali makes no
mistake and converts comfortably.} 34. Bxe4 Bxe4 {Now four pawns and a bishop
versus a rook.} 35. Nd4 Bd5 36. Nb5 a6 37. Nc7 Bc6 38. Rf1+ Kg7 39. Ne6+ Kh6
(39... Kg8?? 40. Rf8#) 40. Rf8 Kh5 41. Rh8 h6 42. Rh7 Kxh4 43. Rxh6+ Kg4 44. Nd4
Kg5 45. Rh2 Bd5 46. Re2 Kf4 47. Rf2+ Nf3 48. Re2 e5 49. Nc2 Be4 50. Ne3 d5 51.
Kb4 Nd4 52. Re1 Kf3 {White resigned as he will lose his knight and pretty much
everything. A tremendous game by Murali and definitely the game of the year!}
