variation promise white an advantage.
WHITE TO
PLAY
10.Ba4 Kh8 11.Bg5 [11.d4!?
e:d4 12.N:d4 with more less equal position] 11...f6 12.Be3 f5 black is
slightly better 13.e:f5 g:f5 14.Bg5 Qe8 15.Ng3 Qg6! Hoping for Bc6?
WHITE TO
PLAY
16.B:c6? Until
depth 15 Rybka consider this move as the best alternative for white. Other way
for white was to play:
16.Qd2!? but then black can play
16
f4 17.Ne4 h6 18.Be7 Rg8 with attack, or
16.Bc1 Ply 16! White idea is to
play d4 and fight for equality, but black can then play 16...f4! Closing Bishop
c1. Now white would have 3 choices:
a) 17.N:h5
Q:h5 18.d4 Bg4 19.d5 Ne7 20.Bc2;
b) 17.Ne4 d5
18.Nc5 Bh3 19.Nh4 Qg5 20.g3 (20.N:b7 Nd8 21.N:d8 Ra:d8 with attack) 20...Rf6
with attack;
c) 17.Nh4
17...Qg4 18.N:h5 (18.Q:g4 B:g4 19.Ne4 Nf6 with better endgame) 18...Q:h4
19.N:g7 K:g7 =+
Back to the game: 16...B:c6 with
better position for black 17.Be7
BLACK TO
MOVE
17
Nf4! White has
very weak white squares 18.Nh4 Qf7 19.B:f8 R:f8 with much more than
compensation for black! 20.Nf3 Rybka "thinks" that white
remain balance... [20.Ng:f5? N:g2+] 20...Bf6 21.b4 h5 Black develops an
attack 22.h4 Qg6 23.a4 b6! to keep bishop on the long diagonal 24.b5
Bb7 25.a5 Engine is not able to feel the danger... yet.
BLACK TO
MOVE
25...N:g2! + 26.K:g2 f4 27.Re4
f:g3 28.f:g3 B:e4 29.d:e4 Q:e4 Black is a pawn up with better
position and Vvarkey Rybka 1.1 had to give up after next 20 moves when reached
score 10 for black.
