I always thought GambitTiger and ChessTiger aren't supposed to give different analysis in endgames, but here apparently they do: 8/k1b5/P4p2/1Pp2p1p/K1P2P1P/8/3B4/8 w - - 0 1 Analysis by Gambit Tiger 2.0: 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Le3 6.a7+ Kb7 +- (2.66) Tiefe: 11 00:00:00 57kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 La5 5.Ld4 Ld2 6.Kb5 Kc7 7.Lxf6 Lxf4 +- (2.98) Tiefe: 11 00:00:00 77kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 Ka8 5.Kb5 Ld6 6.c5 Lc7 7.c6 +- (2.98) Tiefe: 12 00:00:00 112kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 La5 5.Ld4 Ld2 6.Kb5 Lxf4 7.Lxf6 +- (2.94) Tiefe: 13 00:00:01 228kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 La5 5.Ld4 Ld2 6.Kb5 Lxf4 7.Lxf6 Lc7 8.c5 +- (2.94) Tiefe: 14 00:00:03 539kN 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Lg3 6.Kb5 Lxh4 7.b7 Lg3 8.Kxc5 +- (3.10) Tiefe: 14 00:00:04 620kN 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Lg3 6.Kb5 Lxh4 7.Kxc5 f4 8.a7+ Kb7 +- (3.25) Tiefe: 15 00:00:07 1131kN 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Lg3 6.Kb5 f4 7.b7 f3 8.Kc6 Ka7 9.Lc7 Lxc7 10.Kxc7 +- (3.26) Tiefe: 16 00:00:15 2211kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Ka8 4.Kxc5 La5 5.Kd6 Le1 6.Kd7 La5 7.Ke6 Lc3 8.Kxf5 Kb8 9.a7+ +- (3.92) Tiefe: 16 00:00:16 2314kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Ka8 4.Kxc5 La5 5.Kd6 Le1 6.Kd7 La5 7.Ke6 Kb8 8.Kxf5 Le1 9.a7+ Kb7 10.Kxf6 +- (4.30) Tiefe: 17 00:00:25 3742kN 1.b6+ +- (5.20) Tiefe: 18 00:00:44 6488kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Ka8 4.Kxc5 La5 5.Kd6 Kb8 6.Ke6 Ld8 7.Kxf5 Ka8 8.Kg6 Kb8 9.Kxh5 La5 10.a7+ +- (5.36) Tiefe: 18 00:00:47 6992kN 1.b6+ Lxb6 2.Kb5 Lc7 +- (5.36) Tiefe: 19 00:01:41 14182kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Ka8 4.Kxc5 La5 5.Kd6 Kb8 6.Ke6 Ka8 7.Kxf6 Ld8+ 8.Kxf5 Lxh4 9.Kg6 Le1 +- (5.44) Tiefe: 20 00:02:19 19669kN But then I also get analysis different from yours if I'm using ChessTiger: 8/k1b5/P4p2/1Pp2p1p/K1P2P1P/8/3B4/8 w - - 0 1 Analysis by Chess Tiger 14.0: 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Le3 6.a7+ Kb7 +- (2.66) Tiefe: 11 00:00:00 64kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 La5 5.Ld4 Ld2 6.Kb5 Kc7 7.Lxf6 Lxf4 +- (2.98) Tiefe: 11 00:00:00 77kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 Ka8 5.Kb5 Ld6 6.c5 Lc7 7.c6 +- (2.98) Tiefe: 12 00:00:00 112kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 La5 5.Ld4 Ld2 6.Kb5 Lxf4 7.Lxf6 +- (2.94) Tiefe: 13 00:00:01 228kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Kb8 4.Kxc5 La5 5.Ld4 Ld2 6.Kb5 Lxf4 7.Lxf6 Lc7 8.c5 +- (2.94) Tiefe: 14 00:00:03 539kN 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Lg3 6.Kb5 Lxh4 7.b7 Lg3 8.Kxc5 +- (3.10) Tiefe: 14 00:00:04 620kN 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Lg3 6.Kb5 Lxh4 7.Kxc5 f4 8.a7+ Kb7 +- (3.25) Tiefe: 15 00:00:07 1131kN 1.Le3 Lb6 2.Lf2 Kb8 3.Le1 Lc7 4.La5 Lxf4 5.b6 Lg3 6.Kb5 f4 7.b7 f3 8.Kc6 Ka7 9.Lc7 Lxc7 10.Kxc7 +- (3.26) Tiefe: 16 00:00:15 2211kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Ka8 4.Kxc5 La5 5.Kd6 Le1 6.Kd7 La5 7.Ke6 Lc3 8.Kxf5 Kb8 9.a7+ +- (3.92) Tiefe: 16 00:00:16 2314kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Ka8 4.Kxc5 La5 5.Kd6 Le1 6.Kd7 La5 7.Ke6 Kb8 8.Kxf5 Le1 9.a7+ Kb7 10.Kxf6 +- (4.30) Tiefe: 17 00:00:25 3742kN 1.b6+ +- (5.20) Tiefe: 18 00:00:45 6488kN 1.b6+ Lxb6 2.Kb5 Lc7 3.Le3 Ka8 4.Kxc5 La5 5.Kd6 Kb8 6.Ke6 Ld8 7.Kxf5 Ka8 8.Kg6 Kb8 9.Kxh5 La5 10.a7+ +- (5.36) Tiefe: 18 00:00:49 6992kN I'd suspect the differences between mine and your analysis are down to different hashtable size settings or something like that....
