Biel GM 42nd Biel (8), 28.07.2009
[Vachier-Lagrave]

A lot has already been said about this game, but fortunately there still remain many tricky moves to explain!

1.e4 c5 2.Sf3 d6 3.d4 cxd4 4.Sxd4 Sf6 5.Sc3 a6 6.f3 e6 7.Le3 b5 8.Dd2 Sbd7 9.g4 h6 10.0-0-0 b4
I decided to play a different variation from the one I chose against Nakamura recently in San Sebastian. [10...Lb7 11.h4 b4 12.Sa4 Da5 13.b3 Sc5 14.a3 Tc8 ]

11.Sce2 Dc7 12.h4 d5
Up until this point there has been absolutely nothing new, though at that moment Morozevich began to think for 25 minutes. Nevertheless, I thought it was probably some kind of bluff because I had already played this variation and coming into this variation unprepared would be tantamount to suicide...

13.Sf4!N
Proving that I was right. Though this strong novelty doesn't seem to deliver a crushing blow to a variation in which Black anyway doesn't seem to be in trouble, it is really unpleasant to face it over the board.

13...e5!
Clearly the best practical choice. I thought about it for a while to check that at every turn I could have a back-up variation, in case my calculations were wrong at some point. [I think I had planned to play 13...dxe4 14.Sfxe6 fxe6 15.Sxe6 Dc6 16.Sxf8 Sxf8 (16...Txf8?! 17.g5! Sh5 18.gxh6 gxh6 19.Lxh6-> ) 17.Dxb4 exf3 if he had played 13.Sf4, but I didn't take this move seriously enough and so I didn't check the variation thoroughly. It was over the board that I realised that this position was extremely dangerous, e.g : 18.Lf2!? Le6 (18...Sd5 19.Dd4 Se7 20.Dxg7 Tg8 21.De5 Txg4 22.Ld3-> ) 19.Td6 De4 20.Td4 De5 21.Ld3-> All the white pieces are converging on Black's king which is unsafe everywhere. Furthermore, some pawns can fall at anytime, and so the position is very difficult to play, even though it is probably OK if Black plays well.]

14.Sfe6
The obvious continuation of the novelty.

14...fxe6 15.Sxe6 Da5 16.exd5 Dxa2 17.Dd3
Here I got lost in thought, seeing that my first idea was losing by force... Except that it didn't lose !

17...Kf7?
[I was not keen on 17...e4 because of 18.Dd4! (18.fxe4? Se5-/+ ) 18...Ld6 19.Lc4 b3! 20.f4 Da1+ 21.Kd2 Da5+ 22.c3 Da2 23.Ke2!-> Here one can feel that something is wrong: my queen is out of play and my king unsafe. The kingside pawns are going to roll forward with crushing effect (beginning with g5).; 17...Ke7? 18.d6+! Kxe6 (18...Kf7 19.Dc4! Dxc4 20.Lxc4 Kg6 (20...Tb8 21.Sg5+ Ke8 22.Lf7+ Kd8 23.Se6# ) 21.h5+ Kh7 22.g5+- ) 19.Dc4+ Dxc4 20.Lxc4+ Sd5 21.Lxd5+ Kxd6 22.Lxa8++- ; 17...Lb7! was probably the strongest, but I thought that after 18.Dg6+ (18.g5!? is a very interesting idea which offers the opportunity to keep on playing, even though after 18...e4! 19.Sc7+!? (19.Dc4 Dxc4 20.Lxc4 hxg5 21.hxg5 Txh1 22.Txh1 Sxd5 23.Lxd5 Lxd5 24.Sc7+ Kf7 25.Sxd5 exf3= ) 19...Kd8 20.Se6+ Ke8 21.Dd4!? hxg5 22.Sxf8 Sxf8 23.Lc4 Da5 24.Lxg5 S8d7 25.fxe4 Da1+! (25...Dc5? 26.e5! Dxd4 27.Txd4 Sh7 28.Ld2+/- is clearly bad: soon there will be 3 pawns all threatening to queen.) 26.Kd2 Da5 probably holds; I don't see a better idea (even if it's still possible to play on a piece down with some compensation) than to take a draw with 27.Kc1 Da1+ 28.Kd2 Da5= ) 18...Ke7 19.d6+! Kxe6 20.Lh3! I was just lost, but after the very cool (20.g5? Da1+ 21.Kd2 Dxd1+! 22.Kxd1 Lxf3+ 23.Kc1 Lxh1-+ ) 20...Da1+! (20...Ld5? 21.g5+ Kxd6 22.gxf6 Sxf6 23.Txd5+! Dxd5 (23...Kxd5? 24.Df7++- ) 24.Td1+- ) 21.Kd2 Da5! White has no other choice but to repeat moves. 22.Kc1 (22.Ke2? Db5+ 23.Kf2 Ld5! 24.g5+ Kxd6 25.Lxd7 Kxd7 26.gxf6 gxf6-+ And Black just remains a piece up...) 22...Da1+= ]

18.g5
[18.Sd8+? didn't work, and I had even seen the best continuation for Black : 18...Ke7! 19.Sc6+ Kd6! 20.Sxb4? (20.Sd8! Ke7= And Black gets at least a draw.) 20...Da1+ 21.Kd2 Dxb2 22.Dc4 Lb7 23.Ke1 Tc8 24.Sc6 Kc7!-/+ ]

18...Sxd5 19.Lh3!
Here I saw that my problems were anything but over!

19...Sxe3
Probably the best practical choice, even though this move loses by force. [19...S7f6 was my idea when playing 17...Kf7, but after 20.Sd8+ Kg8 (20...Ke8? 21.Dg6+ Kxd8 22.Lb6+ Ke7 23.gxf6+ gxf6 24.Lc5+ Kd8 25.Dxf6+ ) 21.gxf6 Sxf6 I had rightly thought 22.Lf1! was the only move. The only problem was when I understood it was winning because of the threat 23.Dc4+, e.g : 22...Lf5 (22...Le7 23.Sc6!+- ; 22...e4 23.Dc4+ Dxc4 24.Lxc4+ Kh7 25.Sf7 Tg8 (25...exf3 26.Sg5+! hxg5 27.hxg5+ Kg6 28.Txh8 Sg4 29.Txf8+- ) 26.Sg5+ Kh8 27.Lxg8 Kxg8 28.Sxe4+- ) 23.Dxf5 Da1+ 24.Kd2 Txd8+ 25.Ld3+- with a winning attack.]

20.Sd8+ Ke7!
[20...Ke8 was the best choice according to the computer, but only at the beginning. In fact il loses automatically after 21.Lxd7+ Kxd8 22.Lxc8+! First the computer thinks this leads to draw. (22.Le6+ Sd5 23.Lxd5 Da1+ 24.Kd2 Dxb2 25.Lxa8++/- leaves some hope for Black.) 22...Kxc8 (22...Sd5 23.Le6 Tb8 24.De4! Da1+ (24...Tb5 25.Dxe5!+- ) 25.Kd2 Dxb2 26.Ke2!+- with a winning attack.) 23.Dd8+ Kb7 24.Td7+ Kc6 25.Tc7+ Kb6 26.Tc8+ Kb5 27.Txa8 (27.Dd7+ Ka5 28.Dc7+ Kb5 29.Db7+ Ka5 30.Txa8+- is probably simpler.) 27...Da1+ 28.Kd2 Sc4+ 29.Ke2 Dxh1 30.Dd7+! Kb6 31.Tb8+! Kc5 (31...Ka5 32.Tb5+!! axb5 33.Da7# ) 32.Tc8+ Kb6 33.Tc6+ Ka5 34.Dc7++- ]

21.Sc6+ Kf7 22.g6+!
The simplest, and perhaps the most powerful, although there was a well-hidden spectacular win. [22.Le6+!! Kxe6 (22...Dxe6 23.Sd8+ Ke7 24.Sxe6 Kxe6 (24...Sxd1 25.Txd1!+- ) 25.Dxe3+- and the lack of coordination among Black's pieces leaves him no hope of saving the game.) 23.Dg6+ Sf6 24.gxf6 gxf6 25.De8+ Kf5 26.Sd4+! Kf4 27.Se2+ Kf5 Here I had thought this was a draw, but... (27...Kxf3 28.Dc6+!+- ) 28.Td4!!+- The move we probably had both missed. Both threats (29.Sg3# and 29.Tf4+ exf4 30.De4#) are simply too strong.]

22...Kg8
[22...Kf6? 23.Dd6+! Lxd6 24.Txd6+ De6 25.Txe6# ]

23.Dxe3 Lc5 24.De4!
The simplest, and what I was expecting. [24.Le6+! Dxe6 25.Dxc5 Lb7 (25...Dxg6 26.Txd7! Kh7 27.Sxe5+- ) 26.Se7+ Kf8 27.Txd7 Dxd7 28.Sc6+ Kg8 29.Dc4+ Kf8 30.Td1! Dc7 31.Dc5+ Ke8 32.Td6+- is another brilliant win, but is as tough to foresee as 22.Le6+.; 24.Dxc5? Da1+ 25.Kd2 Dxd1+ 26.Txd1 Sxc5 27.Lxc8+/- is still better for White, but 24.De4 is just much stronger.]

24...Sf8 25.Td8 Lb7
Losing on the spot, but there was no other choice. [25...Lxh3 26.Txa8 Le6 27.Dxe5! Dd5 28.Te1! Dxc6 29.Dxe6+ Dxe6 30.Txe6+- is totally hopeless.]

26.Txa8?
Here Morozevich misses probably the simplest shot for a win, even though it is not completely obvious. I had also missed it. [26.Txf8+! Lxf8 (26...Kxf8 27.Df5+! Kg8 28.Dxe5+- ; 26...Txf8 27.Dxe5 Lc8 28.Lxc8 Txc8 29.Dxc5+- ) 27.Dxe5 Lc8 28.De8+- ]

26...Lxa8 27.h5!
The logical follow-up, my pieces are all tangled up, and so I'm still lost ! [27.Td1?? Lxc6 28.Dxc6 Le3+ 29.Td2 Da1# ; 27.Lf1!? Lxc6 28.Lc4+ Se6! 29.Df5! Le3+ 30.Kd1 Lxf3+ 31.Dxf3 Db1+ 32.Ke2 Dxc2+ 33.Kxe3 Dxg6 34.Tf1+- and despite being 3 pawns down, the Se6 is going to be lost, leaving a winning ending for White because Black's pawns are going to fall.]

27...Th7!
A strong defensive move, played because of the necessity of giving up the h8-square for the king; otherwise I'm just going to be mated one way or another.

28.Te1 Lxc6
Unfortunately the only move... [28...Kh8 29.Dxe5!+- ]

29.Dxc6 Ld4 30.Kd2?!
[30.Kd1! Lxb2 31.Lf5 Lc3 32.Ke2! Lxe1 33.Dc8! wins on the spot : 33...Kh8 (33...Lc3 34.gxh7++- ) 34.Dxf8+ Dg8 35.Dxg8+ Kxg8 36.gxh7+ Kh8 37.Kxe1+- ]

30...Dxb2 31.Dc4+ Kh8
Black's Th7 is buried alive. And it will remain there for a while. Indeed why would White take the rook instead of continuing to have mating threats?

32.Kd3! a5
An interesting try, but best was [32...Da3+! 33.Ke4 Da5 with some counterplay with the queen coming back into play.]

33.Dc8?
After this move, I'm not worse anymore ! [33.f4! Lf2 (33...Dc3+ 34.Dxc3 Lxc3 35.Te4! Kg8 36.Tc4+- ) 34.Ke2! Da3 35.Kxf2 Dxh3 36.Txe5 Dh4+ 37.Ke2 Dd8 38.Df7 Dc8 39.Te8+- ]

33...Da3+ 34.Ke4 b3 35.cxb3 a4!
Maybe the move in the game of which I'm the most proud... and it was found in big time trouble. [35...Db4? 36.Tc1 Lc5+ 37.Tc4! De1+ 38.Kd5+/- ]

36.Tb1
A very dangerous move. [36.bxa4 Db4! (36...Lf2!= is also a draw because 35...a4 opened the third rank!) 37.Tc1 Lc5+! and 38.Tc4 is no longer possible. 38.Kd5 Dd4+ 39.Kc6 Dd6+ 40.Kb5 Db6+= ]

36...Db4
[36...Dd6!? is an interesting try for the win, but it is not enough : 37.bxa4 Lc5 38.Td1! Dxd1 39.Dxc5 De2+ 40.Kd5! Dxf3+ 41.Kc4 e4 42.Lf5!= ]

37.Dc4! Db7+ 38.Dd5 Db4
[38...Dxd5+?? 39.Kxd5 a3 40.Tc1! a2 41.Tc8+- ]

39.Dc4 Dd2!? 40.Lg4?
The decisive mistake, on move forty. [40.Dc8! De2+ 41.Kd5 Db5+ 42.Ke4= And the best choice is to get the draw.]

40...a3!-+ 41.Df7 Dc2+ 42.Kd5 Dc5+ 43.Ke4 a2 44.Tc1 a1D! 45.Txc5 Lxc5
Now I'm a rook and a knight up. So, it's all over, even if Black loses the rook, isn't it?

46.Dd5!? De1+ 47.Kd3 Dd1+ 48.Kc4 Dxd5+ 49.Kxd5 La3?!
The following endgame is still winning, but I had a simple tactical shot: [49...Sxg6! 50.hxg6 h5 51.Lh3 Th6 52.Kxc5 Txg6 53.b4 Tg3-+ wins easily, because even if the rook has to be sacrificed for the b-pawn, the 3 remaining pawns helped by the king will win as White's king will be far from the kingside.]

50.Lf5!
[50.Kxe5? Sxg6+! 51.hxg6 h5-+ ]

50...Kg8 51.Kxe5
Obviously White doesn't take the rook, or else the win is easy with a knight up and all the pieces back in play.

51...Th8
Finally the rook remains alive after having been en prise for 24 moves. It will even deliver the final blow!

52.Kd5!
Here I understood that I couldn't free my rook and my king without leaving White with a strong passed pawn on h7.

52...Sh7!
[52...Sxg6?? 53.Lxg6 Kf8 54.Ke6= Even without the b3- and f3-pawns, White would draw easily!]

53.gxh7+ Kf7 54.Lg6+ Kf6
Here I was still 90% sure that the position was winning, as the winning idea is easy to find: stalemate White's king to force the Lg6 to move, when g5 wins because the rook is freed from the protection of the h8-square. In fact it's even easier to apply than I thought it was during the game.

55.f4 Lc1!
I want to get the e5-square for the king.

56.f5
[56.b4!? To push the b-pawn was maybe the most interesting, but after 56...Lxf4 57.b5 Tb8! 58.Kc6 Ke7 59.b6 Lh2 60.b7 Th8(.) White will be in zugzwang: either Black's king comes to the queenside, or Black can play g5... 61.Kb6 (61.Lb1 g5! 62.hxg6 Kf6-+ ) 61...Kd6 62.Lf5 g5! 63.hxg6 Le5 64.Lc8 (64.Ka7 Kc7-+ ) 64...Ld4+!-+ ]

56...Ld2 57.Kd6 Le1 58.Kd7 Lb4!
Cuts White's king off from the kingside before taking the pawn on b3, leaving White no counterplay.

59.Kc7 Ke5 60.Kd7 La3 61.Kc6 Kd4 62.Kc7 Kc3 63.Kd7 Kb4
The first zugzwang of the game; I prevent unnecessary counterplay. [63...Kxb3 64.Lf7+ Kc3 65.Lg8 Kd4 66.Ke6 Ke4 67.f6 gxf6 68.Kxf6 Kf4! 69.Kg6 Lb2-+ was also winning anyway.]

64.Kd6 Kxb3+ 65.Kd5 Lb2 66.Kd6
[Going to the kingside didn't change anything: 66.Ke4 Lf6 67.Lf7+ Kc3 68.Lg6 (68.Lg8 Kd2 69.Kf4 Kd3 70.Kf3 Kd4 71.Kf4 Le7-+ ) 68...Kd2 69.Kf3 Kd3 70.Kf2 Ke4 71.Ke2 Td8! 72.Kf2 Td2+ 73.Ke1 Lc3! 74.f6+ Kf3-+ ]

66...Lf6 67.Kc5 Kc3 68.Kd6 Kd4 69.Kc6
[69.Ke6 Kc5 70.Kf7 with stalemate ideas, doesn't work: 70...Kc6! 71.Ke6 Td8! 72.Kf7 (72.Lf7 Td6# ) 72...Kd6 73.h8D Txh8 74.Lh7 Txh7-+ ]

69...Td8! 70.Kb6
[70.Kb5 Kd5 71.Lf7+ Kd6 72.Lg6 Tc8! 73.Kb4 Kd5 74.Lf7+ Kd4 75.Lg8 Tb8+-+ ]

70...Kd5!
Zugzwang!

71.Kc7
[71.Lf7+ Kd6 72.Lg6 Tb8+-+ ]

71...Kc5 72.Lf7 g5 73.fxg6 Td6 74.Le8 Le5 75.Kb7 Tb6+ 76.Kc8 Kd6
A very exciting game, but also quite frightening! I experienced all sorts of states of mind during this game, and even if I think I got quite lucky, I also found all the moves to remain alive in the game. 0-1
