1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.Ne1 Nd7 10.f3 f5 11.g4!?
An interesting opening plan which I had already used in my game against Radjabov in the Elista Grand-Prix.

11...Kh8 12.Nd3
[In that game I played 12.h4 which is the basic idea in this variation to stop the black kingside expansion by rolling forward my own pawns. But maybe it's a bit premature in this position. 12...c6 13.Kg2 Nf6 14.Nd3 b5! 15.b3 Rb8 16.Nf2 b4 17.Na4 Bb7 18.Bg5 Qd7 19.Qd2 cxd5 20.cxd5 Neg8 21.Rac1 Ba8 22.Qc2 Rf7 23.Qd3 Ne7 24.Kg1 h5 25.Bxf6 Rxf6 26.g5 fxe4 27.fxe4 Rf4 28.Rc4 Rxh4 29.Qg3 Rf4 30.Nd3 Bxd5 31.exd5 Rxc4 32.bxc4 Qxa4 33.c5 Qxa2 34.cxd6 Nf5 35.Rxf5 Qxe2 36.Rf2 Qe4 37.d7 Qxd5 38.Kh2 Kh7 39.Rf6 Qxd7 40.Nxe5 Qd2+ 0-1 Eljanov,P (2720)-Radjabov Teimour (AZE) (2751)/Elista (Russia)]

12...f4!?
Not a novelty but I found only one game from 1967 between high-class GMs of that time.

13.Rf2
An interesting but a bit risky idea as I'm losing too much time to regroup my pieces. [Mecking played the logical 13.Bd2 but I'm not sure that it's the best square for the dark-squared bishop. I like the way Bouaziz played: 13...g5 14.Rc1 Rf7! 15.b4 Nf6 16.c5 Ng6 17.Rf2 Bf8! 18.Qb3 h5 19.h3 Rh7 20.Rh2 Bd7 21.Qc4 Kg7 22.Rf1 Be7 Black's position is very strong, although it's not so easy to break through. 23.Rff2 Qh8 24.Bd1 hxg4 (24...Rh6 25.c6 bxc6 26.dxc6 Be8 27.Bb3 ) 25.hxg4 Rh3 26.Be1 Rg3+ 27.Rfg2 Rxg2+ 28.Rxg2 Qg8 29.Bb3 Nh4 30.Bxh4 gxh4 31.Rh2 Nh7 32.Nb5 Ng5 33.Ne1 Qc8 34.cxd6 cxd6 35.Nc7 b5 36.Qc1 Rb8 37.Rc2 Qb7 38.Ne6+ Bxe6 39.dxe6 Qb6+ 40.Kh1 h3 41.Qd2 h2 42.Qf2 Qxf2 43.Rxf2 Rc8 44.Kxh2 Rc1 45.Ng2 Nh3 46.Rc2 Rxc2 47.Bxc2 Ng5 48.Nh4 Nxe6 49.Nf5+ Kf8 50.Kg2 Ke8 51.Kf2 Kd7 52.a4 bxa4 53.Bxa4+ Kd8 54.Ke2 Ng5 55.Bd1 Kd7 56.Ba4+ Kd8 57.Bd1 Kd7 58.Nxe7 Kxe7 59.Kd3 Ne6 60.Kc4 Nc7 61.b5 Ne6 62.Kb4 Nd4 63.Ka5 d5 64.exd5 Kd6 65.Ka6 Kxd5 66.g5 Ke6 1/2 Mecking,H-Bouaziz,S/Sousse 1967/IZT; The problem is that after 13.h4 Black has a perpetual at least: 13...Bf6 (or 13...Ng8 14.Qe1 (14.g5 h6 ) 14...Bf6 15.g5 Bxg5 (15...Be7 16.Rf2 ) 16.hxg5 Qxg5+= ) 14.g5 Bxg5 15.hxg5 Nxd5 16.cxd5 (16.Rf2 Nxc3 17.bxc3 Qxg5+ 18.Rg2 Qe7 with compensation.) 16...Qxg5+= ; 13.Kh1 g5!? ]

13...Bf6 14.Rg2 Bh4 15.b4 h5
[I was more afraid of 15...Nf6!? 16.c5 h5 17.Bb2 (17.h3 Nh7 18.Bf1 Ng5 19.Rc2 Kg7 with attack.; 17.gxh5 Bh3 ) 17...hxg4 18.fxg4 Nh7 19.Nb5 and the position is still far from clear, but I do not wish to play this position next time :) (19.Ne1? Bxe1 ) ]

16.g5!
A strong pawn sacrifice as 3-4 tempi in this kind of position are more important! [16.gxh5 g5 17.Nf2 Nf6 18.c5 Nxh5 (18...Rg8 19.Ng4 Nxh5 20.Bb2 ) 19.Bb2 (19.Ng4 Nf6 [With attack] ) 19...Nf6 [with initiative] ]

16...Ng8 17.Kh1 Rf7 18.c5 Nf8 19.Nb5 Bh3
The only move as after [19...a6 20.Nxc7! Qxc7 21.cxd6 Qxd6 22.Bb2 Nd7 23.Rc1 despite the fact I have just one pawn for the piece, Black is in very deep trouble I believe.]

20.Rg1 a6 21.Na3
Now all sacrifices are equally dubious as Black is just in time to defend everything. [21.Nxd6 cxd6 22.Bb2 Bxg5 23.cxd6 Bf6 24.Bxe5 Bxe5 25.Nxe5 Rg7 26.Qd2 g5 with a small black advantage.; 21.Nxc7 Qxc7 22.cxd6 Qxd6 23.Bb2 Re8 ]

21...Bxg5
[21...Nh7 22.Nc4 Rg7 23.Bb2 Bxg5 24.Bf1 with a clear advantage for White.]

22.Nc4 Bf6 23.Bf1
[If 23.Bb2 I don't like that after 23...Qe7 24.Bf1 Black has 24...Bd7 hat.]

23...Bc8 24.Bb2 g5?
A huge mistake. [24...Kh7!? ; After the game Ivan proposed 24...Rg7 and this is a good idea although I do not agree of course with his evaluation that Black is much better. My intention was to play something like 25.Qe1 to transfer my queen to f2 (Rybka suggest another way to put Black's queenside under pressure: 25.Qa4!? Bd7 (25...g5 26.Qa5 Qe8 27.cxd6 b5 28.Ncxe5 cxd6 29.Nc6 Bxb2 30.Nxb2 Nf6 31.Qa3 g4 32.Qc3 with white initiative.) 26.Qb3 (26.Qa5 Bb5 27.Rc1 g5 28.Nf2 Nh6 with black initiative.) 26...Bb5 27.Na5 (27.a4 Bxc4 28.Qxc4 g5 29.Nf2 Nh6 30.Be2 Qd7 ) 27...Rb8 28.a4 Be8 29.b5 with good compensation.) 25...g5 26.Qf2 Ng6 (26...g4? 27.cxd6 cxd6 28.Qb6 with white initiative.) 27.cxd6 cxd6 28.Qb6 (28.Rc1 b5 29.Nb6 Rb8 30.Nxc8 Rxc8 ) 28...Qxb6 29.Nxb6 Rb8 30.Rc1 (30.Nc4 Rd7 ) 30...Bd7 31.Nc4 (31.Nxd7 Rxd7 32.Bh3 Rg7 33.Be6 Nh4 ) 31...Nh4 (31...Be7 32.Ncxe5 dxe5 33.Nxe5 Be8 34.Nxg6+ Bxg6 35.Be5 Rd8 36.Bxg7+ Kxg7 37.Rc7 with a small white advantage.) 32.Nxd6 Nxf3 33.Rg2 g4 34.Rgc2 and the position remains very complicated.]

25.cxd6 cxd6 26.Rxg5! Bxg5 27.Ncxe5!?
Not bad, but another possibility which I saw also was stronger: [27.Nxd6! Nh6 28.Nxe5 Kg8 29.Nexf7 Nxf7 30.Nxc8 (30.Nxf7!? Kxf7 31.Qd4 ) 30...Nd7 (30...Rxc8 31.Qd4+- ) 31.Qd4! Bf6 32.Qg1+! Kf8 33.Bxf6 Qxf6 (33...Nxf6 34.Nb6 ) 34.Bh3 Rxc8 35.Bxd7 Rc7 36.Be6+- ]

27...dxe5 28.Nxe5 Kg7
[28...Qe7 29.Nxf7+ Kh7 30.Nxg5+ Qxg5 31.Qd4 ]

29.Nc6+ Qf6 30.Bxf6+ Bxf6 31.e5 bxc6 32.exf6+ Nxf6?
The final mistake. [After 32...Rxf6 I don't see a clear way to victory. Probably the best is 33.dxc6 (33.Bc4 Ne7 34.dxc6 Nxc6 35.Qd5 Ng6 36.Bd3 Ra7 ; 33.Qd4 Ne7 ) 33...Rxc6 34.b5!? (34.Qd5 Ne7 35.Qe5+ (35.Qxh5 Nfg6 36.Bd3 Bb7 ) 35...Kf7 36.Qxf4+ Rf6 37.Qe4 Ra7 ) 34...axb5 35.Bxb5 Rg6 (35...Rf6? 36.Qd5 ) 36.Be8 (36.Qd4+ Nf6 37.Qxf4 Ba6 with a small white advantage.) 36...Rf6 37.Qd4 (37.Qd5 Raa6 38.Rg1+ Ng6 ; 37.Bxh5 Ra5 ) 37...Bb7 38.Bxh5 Kh8 39.Qb2 Bd5 40.a4 with a clear advantage for White.]

33.dxc6 Be6 34.Rc1 Raa7 35.a4 Rae7 36.b5 axb5 37.axb5 N8d7 38.Bc4 Bxc4 39.Rxc4 Ne5 40.Rxf4 Re6 41.Qg1+ Kh8 42.Qc1 Nxc6 43.bxc6 Rc7 44.Rc4 Kg7 45.f4 Kf7 46.f5 Rd6 47.h3 Ng8 48.Rc2 Ne7 49.Qg5 Rcxc6 50.Qxh5+ Kf8 51.Qh8+ Kf7 52.Rg2 Nxf5 53.Qh7+ 1-0
