White has translated his lead in development into an attack. Most opponents will not last long in such a position, but even if they know the best moves they will still stand worse. This is a highly tactical position and it is easy for Black to make fatal missteps 12..0-0 (moves as 12..Kd7??; 12..Qf6?; 12..Bxh2+? or 12..Bf4?! are not sufficient either) 13.Nxd6 Qxf2+ 14.Kh1 Bg4 15.Qd2 Qf6 (The exchange of Queens isn't good: 15…Qxd2 16.Bxd2 threatens Rxe7 and Nxb7, but the big point is White's lead in development and Black's weaknesses such as e6; also 15..Qh4 is answered by Strautins move 16.b4!, White prepares to bring his Bishop to the a1-a8 diagonal, whilst at the same time b4-b5 can be a useful resource – see analysis in previous article, by transposition -; and finally Destrebecq recommendation 15..Nbc6 is replied by 16.Qxf2 Rxf2 17.h3 Bh5 18.Nxb7 – analysis. Test move 15..Qf6 was first played in a game Downey-Melchor, cr. 2nd.. LG WCh., 1997) 16.Qg5 (another possibility is 16.Nxb7 Bf5 17.Qg5 Bxd3 18.Qxf6 Rxf6 19.cxd3 Ng6 20.Bg5 Rb6 21.Nd8 Nd7 22.Re8+Ngf8 23.Rf1 Nf6! =) 16..Nbc6 (and not 16..Qxg5?! as it was played in noted game) 17.Nxb7 (or 17.Qxf6 Rxf6 18.Nxb7 Ng6 – better than 18..Rb8 19.Nc5 Ng6 20.c3- 19.Bg5 Rf7 20.Nc5 Nb4 21.a3 Nxd3 22.cxd3 h6) 17..Qxg5 (now is more correct) 18.Bxg5 Ng6 19.Nd6 (it could be tested 19.Bxg6 hxg6 20.h3 according Stefan Bucker: e.g. 20...Bf5 21.Nd6 Rab8 22.c4 dxc4 23.Nxc4 or perhaps 20...Nb4 21.Re7 Nc6 22.Rc7 Rac8 23.Rxc8 Bxc8 24.Nd6 Bd7 25.Kg1 Rb8 26.b3 Rb6 27.c4, the doubled g-pawn is a handicap, any combined R+B attack on g7 would be almost fatal and pawn a2 is difficult to attack, a7-a5-a4 hardly possible. In spite of the opposite bishops White has substantial chances) 19..Nb4 20.h3 Nxd3 21.cxd3 Bf5 22.Rad1 (22.Nxf5 Rxf5 23.Be3 maybe is slight advantage as White looking for an endgame where often Rook+Bishop is better than Rook+Knight. Also is possible to test 22.Rac1) 22..Rab8 23.b3 (or 23.Rf1 Bd7 24.Rxf8+ Nxf8 25.Rd2) 23..Bd7 24.Be3 a6?! (24..Rf6 25.Bc5 a6) 25.Rf1 (25.Bd4!) 25..Ne7 (probably is better 25..Rxf1+ 26.Rxf1 Bb5) 26.Bc5 Nf5 27.Rfe1 Rf6 28.Nxf5 Rxf5 29.g4 (29.Re7!? Rf7 30.Rde1) 29..Rf8 30.Kg2 Rc8 31.b4 Re8 and soon – move 42- game finished in draw Melchor-Trofimov, cr. e-mail, 6th. LG WCh. final, 2010/11
This game has been of a great importance if it was not the Black has to worry about a knight sacrifice on d5 one move before!!: 10.Nexd5! cxd5 11.Nb5 and now 11..Qd7?; 11..Bf4?; 11..Bf8? or relatively best 11..Bc7 of a recent game is illustrative: 12.Re1+ Kd8 (I add 12..Kf8? 13.b3 with attack) 13. Bg5+ Nf6 14.Be4! (I. Terenin, 2011; 14.Bc4 looks promising, but disables c2-c4 option, so after 14..Be6 15.Bxd5 Bxd5 16.c4 Kc8 - or 16..Nbd7!? - 17.Bxf6 Bf3! etc. Melchor-Sakai, cr. e-mail, 5th. LG World Ch., sf. A, 2004/05, 1/2-1/2, 36 or 15.Rxe6!? Qxe6 16.Bxd5 Qe5 17.Bxb7+ Nbd7 etc. with a very complicated game for both players - you can continue analyzing this great line! -) 14..Re8 (14..Be6 15.c4 crushes Black center) 15.Bxd5 Rxe1+ 16.Qxe1 Bxh2+ 17.Kf1 Qe8 18.Qxe8+ Kxe8 19.Bxf6 gxf6 20.g3. Igor Terenin ask if Black can hold this position. First impression is that he can't due to much less active pieces and weakness of his kingside pawns.
Well, according my own experience it’s reasonably easy to increase the advantage: So, 20..Bxg3 21.fxg3 Kd8 22.Rd1 Nd7 23.Kf2 (23.Kg2) 23..a5 24.c4 h6 25.Rd4 f5 26.Nd6 Kc7 27.Be6 Nb6 28.Bxc8 Nxc8 29.Nxf5 Ra6 30.Kf3 and White won a difficult ending in Melchor-Borrmann, cr. e-mail, LADAC thema Final, 2010/11
