I have a different analysis by Chess Tiger 14.0 and Chess Tiger 15.0 ga and normal. Maybe you don't have KPPKP endgame tablebase or we have different sets of tablebases. CT14 finds the draw instantly, while CT15 in 29 seconds finds the drawing move. --------------------------------------------------------------------------- Analysis by Chess Tiger 14.0: 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 = (-0.12) Depth: 12 00:00:00 127kN, tb=1 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 = (-0.02) Depth: 12 00:00:00 174kN, tb=2 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 Kc5-d5 = (-0.02) Depth: 13 00:00:01 320kN, tb=7 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 Kc5-d5 8.Kc3-d3 = (0.00) Depth: 14 00:00:02 686kN, tb=23 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 Kc5-d5 8.Kc3-d3 Kd5-c5 = (0.00) Depth: 15 00:00:03 1122kN, tb=85 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 Kc5-d5 8.Kc3-d3 Kd5-c5 9.Kd3-e4 = (0.00) Depth: 16 00:00:06 1854kN, tb=298 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 Kc5-d5 8.Kc3-d3 Kd5-c5 9.Kd3-e4 Kc5-c4 = (0.00) Depth: 17 00:00:11 3091kN, tb=896 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 Kc5-d5 8.Kc3-d3 Kd5-e5 9.Kd3-e3 Ke5-d5 10.Ke3-d3 = (0.00) Depth: 18 00:00:20 5431kN, tb=2341 1.Kd5-e5 Kc7-c6 2.Ke5-d4 f7-f6 3.h3-h4 b5-b4 4.a3xb4 a5xb4 5.Kd4-c4 b4-b3 6.Kc4xb3 Kc6xc5 7.Kb3-c3 Kc5-d5 8.Kc3-d3 Kd5-e5 9.Kd3-e3 Ke5-d5 10.Ke3-d3 = (0.00) Depth: 19 00:00:35 9317kN, tb=5471 --------------------------------------------------------------------------- Analysis by Chess Tiger 15.0 ga and normal: 61.c5-c6 b5-b4 62.a3xb4 a5xb4 63.Kd5-c4 Kc7xc6 64.Kc4xb4 f7-f5 65.g4xf5 = (0.00) Depth: 14 00:00:00 119kN, tb=26 61.c5-c6 b5-b4 62.a3xb4 a5xb4 63.Kd5-c4 Kc7xc6 64.Kc4xb4 f7-f5 65.g4xf5 = (0.00) Depth: 14 00:00:00 134kN, tb=29 61.c5-c6 b5-b4 62.a3xb4 a5xb4 63.Kd5-c4 Kc7xc6 64.Kc4xb4 f7-f5 65.g4xf5 = (0.00) Depth: 15 00:00:00 247kN, tb=58 61.c5-c6 b5-b4 62.a3xb4 a5xb4 63.Kd5-c4 Kc7xc6 64.Kc4xb4 f7-f5 65.g4xf5 = (0.00) Depth: 16 00:00:01 362kN, tb=111 61.c5-c6 b5-b4 62.a3xb4 a5xb4 63.Kd5-c4 Kc7xc6 64.Kc4xb4 f7-f5 65.g4xf5 = (0.00) Depth: 17 00:00:02 533kN, tb=205 61.c5-c6 b5-b4 62.a3xb4 a5xb4 63.Kd5-c4 Kc7xc6 64.Kc4xb4 Kc6-d5 65.Kb4-c3 Kd5-e4 66.Kc3-c4 Ke4-f4 67.Kc4-d5 Kf4-g3 68.Kd5-e5 Kg3xh3 69.Ke5-f4 Kh3-h4 70.Kf4-f5 µ (-0.86) Depth: 18 00:00:03 836kN, tb=423 61.c5-c6 b5-b4 62.a3xb4 a5xb4 63.Kd5-c4 Kc7xc6 64.Kc4xb4 Kc6-d5 65.Kb4-c3 Kd5-e4 66.Kc3-c4 Ke4-f4 67.Kc4-d5 Kf4-g3 68.Kd5-e5 Kg3xh3 69.Ke5-f4 Kh3-h4 70.Kf4-f5 µ (-0.86) Depth: 19 00:00:10 3126kN, tb=848 61.Kd5-e5 Kc7-c6 62.h3-h4 b5-b4 63.a3xb4 a5xb4 64.Ke5-d4 b4-b3 65.Kd4-c3 Kc6xc5 66.g4-g5 h6xg5 67.h4-h5 g5-g4 68.h5-h6 g4-g3 69.h6-h7 g3-g2 70.h7-h8Q g2-g1Q 71.Qh8-e5+ µ (-1.16) Depth: 20 00:00:29 9132kN, tb=2209 61.Kd5-e5 Kc7-c6 62.h3-h4 b5-b4 63.a3xb4 a5xb4 64.Ke5-d4 b4-b3 65.Kd4-c3 Kc6xc5 66.g4-g5 h6xg5 67.h4-h5 g5-g4 68.h5-h6 g4-g3 69.h6-h7 g3-g2 70.h7-h8Q g2-g1Q 71.Qh8-e5+ µ (-1.16) Depth: 21 00:00:48 15686kN, tb=3095 61.Kd5-e5 Kc7-c6 62.h3-h4 b5-b4 63.a3xb4 a5xb4 64.Ke5-d4 b4-b3 65.Kd4-c3 Kc6xc5 66.g4-g5 h6xg5 67.h4-h5 g5-g4 68.h5-h6 g4-g3 69.h6-h7 g3-g2 70.h7-h8Q g2-g1Q 71.Qh8-e5+ µ (-0.92) Depth: 22 00:01:47 36131kN, tb=5191
