A King's Indian game from the Odessa tournament
1.d4 Nf6 2.Nf3 d6 3.c4 g6 4.g3 Bg7 5.Bg2 0-0 6.0-0 Nbd7 7.Qc2 This is an important alternative to the main line with 7.Nc3. 7...e5 8.Rd1 Re8 Of course, not 8...c6? 9.dxe5 dxe5 10.Nxe5 ±, but possible is 8...Qe7 9.Nc3 c6, which sometimes may lead to the same positions as 8...Re8. 9.Nc3 There is also GM Romanishin's line 9.dxe5 dxe5 10.e4 c6 11.h3. This year, I experimented with 11...Qb6N in the game versus IM Ardelean. It continued 12.Be3 Nc5 (12...Qb4?! 13.a3!) 13.Nc3 Qb4 14.Bf1 Bf8 15.Kh2 (15.a3!? Qb3) and here 15...a5! would have been correct. 9...c6 10.b3 10.e4 occurs more often. If Black responds with 10...exd4 11.Nxd4 Qe7, then White is not forced to transpose to the game by 12.b3 (both 12.Be3!? and 12.Bf4!? are important options). 10...Qe7 11.e4 Playable for Black is 11.Ba3 e4 12.Ng5 e3 as is in the famous game Ivanchuk-Yusupov, Brussels (m/9) 1991. 11...exd4 12.Nxd4 Nc5 13.f3 Nfd7! This is more precise than 13...a5 14.Be3! followed by 15.Bf2. 14.Bb2 White also can try to do without this move: 14.Rb1 Ne5 15.Nce2 (15.h3 a5 16.a3?! a4! 17.b4 Nb3 Matlak-Golubev, Karvina op 1992/93) 15...a5 16.a3 h5 17.h4 (17.b4 axb4 18.axb4 Ne6 19.f4 Nxd4 20.Nxd4 Ng4 21.h3 Nf6 22.Re1 h4 23.gxh4 Nxe4! Loginov-Golubev, Loosdorf op 1993) 17...Bd7 {unclear} Salov-Kasparov, Linares 1991. After 14.Be3 Black has 14...f5!. 14...a5 It is also possible to begin with 14...Ne5. 15.Nce2 Ne5 White's position is a bit passive, but it is very solid and he may hope that Black's inferior pawn structure will start to tell sooner or later. 16.Bc3!? In the 1990 the position after 16.Rab1 twice occurred in my games (however, in Kharitonov-Golubev, Alushta 12 1994, the draw was agreed there immediately). 16...h5 17.h3N Generally, h3 is the most standard White's reaction to ...h5 in the entire system. (White is not weakening anything and prepares to answer ...h4 with g4.) A curious 17.Be1!? (planning Bf2) 17...g5!? was tried in Prie-Degraeve, Toulouse 1995. Of course, I was unawared... I barely can remember my own games, to be honest. 17.h4 weakens g4 and should be playable for Black. 17...a4!? A committal decision: further opening of the a-file may help Black to develop activity, but from another point of view, Black always should be ready to meet b4 starting from now. Both 17...h4 and 17...g5 can be considered (but at this point I did not wish to advance my g-pawn so early). 18.Rab1 Not forced. Perhaps, 18.Kh1!? is a decent alternative. 18...axb3 19.axb3 g5!? 19...Bh6 (as I once played in similar position against Forintos) hardly makes much sense: 20.Kh1! h4 21.g4 Qf6 and now 22.f4! Bxf4 23.Rf1 g5 is very dubious for Black. Maybe 19...h4 20.g4 g5 21.b4 Na4 is better than I thought. 20.g4 My idea was to meet the principled 20.b4 by 20...g4!? with some extreme complications.20...hxg4 21.hxg4 Nxg4! 22.fxg4 Nxe4! 22...Bxg4? is strategically refuted by 23.Ng3! Bxd1 24.Rxd1 ±. 23.Bb2!? Bxg4 I started to like (overestimate?) my position, and declined the draw offer. But White found a very interesting reply.24.Bxe4 Qxe4 25.Qxe4 Rxe4 26.Ng3! And Black can not win material. 26...Re5!? Trying to restrict White's knights. A fighting idea, what perhaps is its only good side. Both 26...Rf4 27.Nde2! Rf3 28.Bxg7 Kxg7 29.Rxd6 Ra2! = and 26...Re3 27.Ngf5! (27.Ndf5? Rxg3+! 28.Nxg3 Bxb2 29.Rxd6) 27...Bxd4 (27...Bxf5? 28.Nxf5 +-) 28.Bxd4! Re6 29.Rf1! Ra2 = results in approximate equality. 27.Rf1 I expected 27.Ra1 where 27...Rea5 28.Rxa5 Rxa5 =+ is quite good for Black. But 27.Rd3!? surely deserved attention. 27...Ra2 28.Rf2 There is no sense for White to go for 28.Ndf5?! Rxf5 29.Nxf5 Bxf5 30.Rxf5 and Black avoids the exchange of his only rook by 30...Bxb2!. Of some interest was 28.Nc2!?. 28...c5 Totally missing White's next - but I had only some 2 minutes left on the clock. 28...Rea5! 29.Bc3 Rxf2 30.Kxf2 Ra2+ 31.Rb2 Rxb2+ 32.Bxb2 should be better for Black if he avoids 32...c5 33.Ndf5! Bxf5 34.Bxg7 Bc2 35.Bf6 =. 29.Nc2! Better than 29.Ndf5 Rxf5 30.Nxf5 Bxf5 31.Rxf5 Bxb2! and especially 29.Nb5? Re3! 30.Nf1 Rxb3 (30...Rf3!?) 31.Bxg7 Rxb1 32.Rxa2 Kxg7 33.Nxd6 Bh3 34.Rf2 Kg6. 29...Rxb2 A normal continuation, which I disliked, was 29...Re7 30.Bxg7 Kxg7. White certainly has a draw - for example, 31.Rbf1 Rb2 32.Ne3 Rxe3 33.Rxf7+ Kg8 34.Rf8+ = , but hardly more. 30.Rxb2 f5! I expected that Black can be a bit worse here, but not much worse: he controls many squares, the compensation for a rook is quite real. 31.Ra2 After 31.Rb1!? f4 32.Nf1 I planned 32...Bf5!? (but there are many alternatives, even 32...Re2). 31...f4 32.Nf1 Bf5 33.Nh2 Re8 Around here the game entered into the mutual eternal Zeitnot (30 seconds per move). 34.Rg2 Bf6 35.Ng4 Bg7 36.Nf2 Hardly the best. 36...Re2! 37.Nh3 After 37.Nh1 Rxg2+ 38.Kxg2 g4! Black is doing well. Quite crazy is the engine's suggestion 37.Nb4 Re1+ 38.Kh2 cxb4 39.Rxg5 Bb1. 37...f3?! Missing a much simpler solution: 37...Rxg2+! 38.Kxg2 f3+! 39.Kf2! (39.Kxf3?! g4+!) 39...Bxh3 40.Kxf3 g4+!? (otherwise 41.Ne3) 41.Kg3 Be5+ 42.Kh4 Bf6+ = with a draw. 38.Ra8+! Kh7 38...Kf7 39.Nxg5+ Kf6! was probably somewhat more precise. 39.Nxg5+ Not 39.Rxg5? Bxc2 40.Rh5+ Bh6!. 39...Kg6 Not 39...Kh6? 40.Nf7+. 40.Nxf3+ Deserved attention 40.Rg3!? and then, e.g. 40...Rg2+ 41.Rxg2 fxg2 42.Ne3 Bd4 43.Rg8+ Kf6 44.Rf8+ Kg6 45.Kxg2 Bxe3 46.Nf7!? +=. 40...Rxg2+ 41.Kxg2 Bxc2 42.Nd2 42.Rd8 hardly could make much trouble for Black as well. 42...Bc3 43.Rd8 Declining the draw offer. After 43.Ra2 I would play 43...Bd1 44.Ne4 Be5 =. 43...Bxd2 44.Rxd6+ Kf5 45.Rxd2 Bxb3 46.Rd5+ Ke4 47.Rxc5 Kd4 48.Rb5 Draw, anyway.
