Zappa 1.1 appears to be performing around 150 elo points below Fruit 2.1, at least at the Playchess server. It's a mystery to me how the author managed to make it so strong as to get the WCCC, but he did it and deserves kudos... Anyway, Fruit 2.1 finds the nice move as well, quite quickly, and on a single cpu (only 64 meg hash). Takes 37 seconds for the splendid rook sac: New game, b2r3r/k4p1p/p2q1np1/NppP4/3p1Q2/P4PPB/1PP4P/1K1RR3 w - - 0 1 Analysis by Fruit 2.1: 1.Qxd6 Rxd6 ² (0.66) Depth: 1/2 00:00:00 1.Qxd6 Rxd6 2.Re7+ Kb6 ± (1.01) Depth: 2/10 00:00:00 1.Qxd6 Rxd6 2.c4 dxc3 3.Re7+ Kb6 = (0.15) Depth: 3/14 00:00:00 1.Qxd6 Rxd6 2.c4 dxc3 3.Re7+ Kb6 = (0.15) Depth: 4/15 00:00:00 1.Qxd6 Rxd6 2.b4 cxb4 3.Re7+ Kb8 4.axb4 Nxd5 = (0.08) Depth: 5/18 00:00:00 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 = (0.11) Depth: 5/18 00:00:00 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 Re8 ³ (-0.30) Depth: 6/20 00:00:00 46kN 1.Qxd6 Rxd6 2.b4 cxb4 3.Re7+ Kb8 4.axb4 Nxd5 = (0.08) Depth: 6/20 00:00:00 63kN 1.Qxd6 Rxd6 2.b4 cxb4 3.Re7+ Kb6 4.axb4 Nxd5 5.Rxf7 Nc3+ 6.Kc1 Nxd1 7.Kxd1 µ (-0.86) Depth: 7/20 00:00:00 177kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 Re8 6.f4 = (-0.22) Depth: 7/20 00:00:00 190kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 h6 6.Re7 Re8 = (-0.10) Depth: 8/26 00:00:01 298kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Kb6 4.Re7 Kxc6 5.Rxf7 Re8 6.f4 = (-0.22) Depth: 9/26 00:00:01 509kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Kb6 4.Re7 Kxc6 5.Rxf7 Re8 6.Ra7 Kb6 ³ (-0.37) Depth: 10/29 00:00:01 960kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 Re8 6.Bd7 Nxd7 7.Rxd7 Rf6 8.f4 h6 ³ (-0.51) Depth: 11/29 00:00:02 2117kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 Re8 6.Bd7 Nxd7 7.Rxd7 Rf6 8.f4 h6 9.Ka2 ³ (-0.51) Depth: 12/39 00:00:04 4590kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 Re8 6.Bd7 Nxd7 7.Rxd7 Rf6 8.f4 h6 9.c3 Kc6 ³ (-0.49) Depth: 13/39 00:00:06 8668kN 1.Nc6+ Bxc6 2.Qxd6 Rxd6 3.dxc6 Rxc6 4.Re7+ Kb6 5.Rxf7 Re8 6.Bf1 h6 7.Bd3 g5 8.f4 gxf4 9.gxf4 c4 10.Bf5 ³ (-0.48) Depth: 14/41 00:00:11 16694kN 1.Rxd4 Kb6 2.b4 Qxf4 3.Rxf4 Nxd5 4.Rxf7 cxb4 5.axb4 Nxb4 6.Nb3 Rdf8 7.Rxf8 Rxf8 8.f4 Bd5 9.Re7 ³ (-0.29) Depth: 14/50 00:00:37 52685kN 1.Rxd4 Kb6 2.Nb3 Bxd5 3.Rxd5 Nxd5 4.Qxf7 Rhf8 5.Qxh7 Rh8 6.Qf7 Nc7 7.Bg4 c4 8.Nc1 Rxh2 ³ (-0.62) Depth: 15/50 00:01:02 86938kN (Vidanovic, Home 15.09.2005)
