Grand Slam Final Masters 2010 Bilbao/Spain (4), 13.10.2010
[Romain Edouard]



1.e4 e6
Whoa! No Ruy Lopez, no Petroff thank you!

2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.e5 h6 6.Bd2 Bxc3 7.bxc3 Ne4 8.Qg4 g6
[8...Kf8 has also been quite popular recently.]

9.Bd3 Nxd2 10.Kxd2 c5 11.h4!? Qa5!?
[11...Nc6 is the main possibility. In both cases, there are some side-moves to explore, while it could go 12.Nf3 Qa5 getting back into the game. So there might be some differences.]

12.Nf3 Nc6 13.Qf4 cxd4 14.h5!
[14.Nxd4 Nxd4 15.Qxd4 Bd7 is the usual (less fascinating) concept!]

14...g5
[Without entering big calculations, I would say that Black has enough time to take on c3, so 14...dxc3+ 15.Ke2 cannot help him defending.; 14...Qxc3+ 15.Ke2 gxh5 16.Rab1 would be very dangerous for Black: White will go Rxh5, Rxh6, and Ng5-Nh7 in the event of ...Rf8. Still, maybe this is the line to be checked, as the game looks clearly in White's favour.]

15.Qf6 Rf8
[15...Rg8!? 16.Qxh6 g4 17.Ng5 dxc3+ 18.Ke2 Nxe5 19.Qf6 Qd8 could be a possibile defense, the rook on g8 making a huge difference in this final position!]

16.Qxh6 g4!? 17.Ng5 Nxe5 18.Nh7 Rh8 19.Ke2!
This is the proof that taking on c3 earlier could hardly help. After this prophylactic move, Black suffers huge troubles. White's king is in perfect position and Black has problems in finding solutions.

19...Nxd3
[19...Qxc3 20.Nf6+ Ke7 21.Qg5! Kd6 22.Qf4+- ]

20.cxd3 Bd7
[20...Qxc3 21.Rhc1 Qb2+ 22.Kf1 just wins.]

21.Nf6+ Ke7 22.Qg5 dxc3


23.Ne4+
[The silicon move 23.h6! was winning! For instance: 23...Bb5 (23...Qa4 24.Nxg4+ Ke8 (24...Kd6 no longer works due to 25.Qe5++- and c3 is hanging.) 25.Qg7 Ke7 (25...Qc2+ 26.Kf1 Qxd3+ 27.Kg1 Ke7 28.Qf6+ Kd6 29.Ne5+- ) 26.Qf6+ Kd6 27.Qe5++- ; 23...Kd6 24.Ne4+! Kc6 25.Qe5! Qa3 26.Rhc1+- ) 24.a4! Ba6 (24...Bxd3+ 25.Kxd3 Qa6+ 26.Ke3 Qb6+ 27.Ke2 Qb2+ 28.Kd3+- ) 25.Nxd5+ Kd6 26.Qe7+! Kxd5 27.Rh5+ f5 28.Qd7+ Kc5 (28...Ke5 29.Ke3!!+- followed by d4+ and Qg7 mate (or Qd4 mate).) 29.Rxf5+ exf5 30.Qxf5+ Kb6 31.Rb1++- ]

23...Ke8 24.Nf6+ Ke7 25.Nxg4+ Kd6 26.Ne5
White is threatening Nc4+.

26...f6
The only way to get some counterplay!

27.Qxf6 Raf8


28.Qg7??
Crazy move! Losing an exceedingly important tempo. Difficult to know what Anand missed. [28.Nf7+ Rxf7 29.Qxf7 Qa4 would be a totally different story, as it would be White to move! And for instance, after 30.Kf1 Qc2 (30...Qd4 31.Qf3 Bb5 32.Rh3 c2 33.Rc1 Qb2 34.Qf4+ e5 35.Qd2+- ) 31.Qf4+! Kc6 32.h6 White should win. (32.Rh3!? ) ]

28...Qa4
[28...Qb6! might be best!! Typical computer move, forcing White to go Nf7+ according to the engine, as 29.Qxd7+? Kxe5 should be much better for Black, whose king is going to move back to d6 or f6, depending on White's move.]

29.Nf7+
[29.Qg3!? was was still very tricky: probably that's why Black should rather go 28...Qb6! 29...Qc2+ 30.Kf1 Bb5!? (30...Qxf2+ 31.Qxf2 Rxf2+ 32.Kxf2 Kxe5 33.Rae1+!? Kd4 34.Ke2 should win for White.) 31.Nf7+ Ke7 32.Nxh8 Qxd3+ Only move. 33.Qxd3 Bxd3+ 34.Kg1 Rxh8 35.Rh3! Lucky move. 35...Bc4 36.Rxc3 Rxh5 and Black keeps drawing chances, but I believe White should still be winning.]

29...Rxf7 30.Qxf7 Qc2+ 31.Kf1 Qxd3+ 32.Kg1
The difference between 29.Nf7+ and 28.Nf7+ has been huge, but White should hold a draw anyway.

32...Qd2 33.Qg7 c2
[33...Rc8!? 34.h6 c2 35.Qg3+ e5 36.Qa3+ Ke6 37.Qc1 and White holds thanks to the following idea: 37...Qc3 38.h7 Qxa1 39.Rh6+ Phew! 39...Kf5 40.Qxa1 c1Q+ 41.Qxc1 Rxc1+ 42.Kh2 Rc8 43.h8Q Rxh8 44.Rxh8+/= ; 33...Rh6 34.Rh3 c2 35.Qg3+ Ke7 36.Qa3+ Ke8 37.Rf1 with counterplay.]

34.Qxh8 c1Q+ 35.Rxc1 Qxc1+ 36.Kh2 Qf4+ 37.Kg1 Qc1+ 38.Kh2
1/2-1/2
