Perhaps Black could do better than 14...Rc8. It looks like Black is in a difficult position after 15. Qh3. I too, however, will defer judgment to someone with a better eye for this position. But after 16.Bxh6, F6 thinks Black is OK until he gets to the 15th ply, after searching more than 2 billion nodes, he suddenly (as judged by ply depth, not elapsed time - he he) drops the score from 0.00 to +0.75. And I suspect it would only get worse. Here is analysis from Fritz 6 after 16.Bxh6: [D]2rq1rk1/1p2bpp1/pnb1pn1B/4N3/P2P4/1BN4Q/1P3PPP/R4RK1 b - - 0 1 Analysis by Fritz 6: 16...g7xh6! = (0.00) Depth: 1/1 00:00:00 16...g7xh6 = (0.00) Depth: 2/2 00:00:00 16...g7xh6 = (0.00) Depth: 3/3 00:00:00 16...g7xh6 = (0.00) Depth: 4/4 00:00:00 16...g7xh6 = (0.00) Depth: 5/5 00:00:00 16...g7xh6 = (0.00) Depth: 6/6 00:00:00 16...g7xh6 = (0.00) Depth: 7/7 00:00:00 2kN 16...g7xh6 = (0.00) Depth: 8/8 00:00:00 89kN 16...g7xh6 = (0.00) Depth: 9/9 00:00:00 178kN 16...g7xh6 = (0.00) Depth: 10/10 00:00:01 865kN 16...g7xh6 = (0.00) Depth: 11/11 00:00:01 979kN 16...g7xh6 17.Qh3xh6 Nb6-d5 18.Qh6-g5+ Kg8-h8 19.Bb3-c2 Nd5xc3 20.Qg5-h4+ Kh8-g8 21.Qh4-g5+ = (0.00) Depth: 12/36 00:00:37 21216kN 16...g7xh6 17.Qh3xh6 Nb6-d5 18.Qh6-g5+ Kg8-h8 19.Bb3-c2 Nd5xc3 20.Qg5-h4+ Kh8-g8 21.Qh4-g5+ = (0.00) Depth: 13/41 00:02:44 94240kN 16...g7xh6 17.Qh3xh6 Nb6-d5 18.Qh6-g5+ Kg8-h8 19.Bb3-c2 Nd5xc3 20.Qg5-h4+ Kh8-g8 21.Qh4-g5+ = (0.00) Depth: 14/41 00:07:31 260637kN 16...g7xh6-- ² (0.47) Depth: 15/42 00:27:17 916404kN 16...g7xh6-- 17.Qh3xh6 Nb6-d5 18.Rf1-e1 Nf6-g4 19.Ne5xg4 Be7-g5 20.Qh6-h3 Nd5-f4 21.Qh3-g3 ± (0.75) Depth: 15/44 00:59:37 2027730kN (Wilson, Columbia 10.03.2001)
