r1b1kb1r/1p1n1ppp/p2ppn2/6BB/2qNP3/2N5/PPP2PPP/R2Q1RK1 w kq - 0 1 Nolot's analysis as reported by Baudot: Bronstein - Kotov, candiates, Budapest 1950 10.Nxe6!! Qxe6 11.Nd5 Kd8 12.Bg4 Qe5 13.f4 Qxe4 (13...Qxb2 was stronger but not sufficient : 14.Bxd7 Bxd7 15.Rb1 Qa3 16.Nxf6 Bb5 17.Qd4 Qc5 18.Rfd1 +-) 14.Bxd7 Bxd7 15.Nxf6 gxf6 16.Bxf6+ Kc7 17.Bxh8 and Kotov resigned on move 27. Tasc R30 (The King), the strongest program for this kind of combination, would need a few weeks here. Comments by Feng-Hsiung Hsu: Solution: 1. Ne6 Qe6 2. Nd5 Kd8 3. Bg4. Plays it after 3.8 hours, would play it under 2.5 hour/move time control. My own experience: My program finds this after 34 hours on a quad 450 mhz Xeon machine, with a score of +1. It's possible that the solution is getting lost in noise a little bit, since there are several moves that are a little worse than +1 in the version of Ferret that I used. |
