As far as I know there is a bug that I already posted and called it a hash bug. You may call it in another name but it is clearly a bug unless my hardware is broken but I did not read that other people cannot reproduce the problem that I posted. see http://www.talkchess.com/forums/1/message.html?456243 It is also clear that after Rxd2 Fruit can see very fast that white is clearly better(at depth>=14 the score is at least +1 for white) so if it force that trade one move earlier at depth 20 there is a problem. 229: Shredder 9 Columbus'egg 9g - Fruit 2.2 Uri, CEGT 40/40 (2 Ghz) 2005 8/8/5k2/8/6p1/4K1P1/3r1P2/8 w - - 0 1 Analysis by Fruit 2.2 Uri: 142.Kxd2 Ke5 ± (0.86) Depth: 1/4 00:00:00 142.Kxd2 Ke5 143.Kd3 ± (0.78) Depth: 2/4 00:00:00 142.Kxd2 Ke5 143.Kd3 Kd5 ± (0.98) Depth: 3/4 00:00:00 142.Kxd2 Ke5 143.Kd3 Kd5 144.Ke3 ± (0.78) Depth: 4/7 00:00:00 142.Kxd2 Ke6 143.Kd3 Kd5 144.Ke3 Ke5 ± (0.98) Depth: 5/9 00:00:00 142.Kxd2 Ke6 143.Kd3 Kd5 144.Ke3 Ke5 145.Kd3 ± (0.78) Depth: 6/9 00:00:00 1kN 142.Kxd2 Ke6 143.Ke2 Kd5 144.Kd3 Ke5 145.Ke3 Kd5 ± (0.98) Depth: 7/11 00:00:00 3kN 142.Kxd2 Ke6 143.Ke2 Kf6 144.Ke3 Ke5 145.Kd3 Kd5 146.Ke3 ± (0.78) Depth: 8/12 00:00:01 6kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.Kd3 Kd5 145.Kc3 Kc5 146.Kd2 Kd5 ± (0.86) Depth: 9/14 00:00:01 10kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.Ke3 Ke5 145.Kd3 Kd5 146.Kc3 Ke4 147.Kc4 ± (0.78) Depth: 10/14 00:00:01 14kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.Ke3 Ke5 145.Kd3 Kd5 146.Kc3 Kc5 147.Kd2 Kd4 ± (0.86) Depth: 11/16 00:00:01 19kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.Ke3 Ke5 145.Kd3 Kd5 146.Kc3 Kc5 147.Kd2 Kd4 148.Ke2 ² (0.66) Depth: 12/17 00:00:01 34kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.Ke3 Ke5 145.Kd3 Kd5 146.f3 gxf3 147.Ke3 Ke5 148.g4 f2 149.Kxf2 ² (0.65) Depth: 13/19 00:00:01 43kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f3 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kf5 148.g4+ Kf6 149.Kh6 Ke6 150.g5 Ke5 ± (1.05) Depth: 14/21 00:00:01 77kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f3 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kg7 148.Kg5 Kf7 149.Kf5 Ke7 150.Ke5 Kd7 ± (1.24) Depth: 15/23 00:00:02 134kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f3 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kg7 148.Kg5 Kf7 149.Kf5 Kg7 150.Ke5 Kg6 151.Ke4 ± (1.16) Depth: 16/25 00:00:02 160kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f3 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kg7 148.Kg5 Kf7 149.Kh6 Ke6 150.g4 Kd5 151.g5 Ke5 ± (1.05) Depth: 17/25 00:00:02 270kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f4 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kg7 148.Kg5 Kf7 149.Kh6 Ke6 150.g4 Kd5 151.g5 Ke5 152.g6 +- (1.49) Depth: 18/27 00:00:02 1549kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f4 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kg7 148.Kg5 Kf7 149.Kh6 Ke6 150.g4 Kf7 151.g5 Kg8 152.Kg6 Kf8 +- (1.72) Depth: 19/29 00:00:03 5210kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f4 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kg7 148.Kg5 Kf7 149.Kh6 Ke6 150.g4 Kf7 151.g5 Kg8 152.Kg6 Kf8 153.Kf5 +- (1.93) Depth: 20/31 00:00:08 14608kN 142.Kxd2 Ke6 143.Ke2 Kd6 144.f4 gxf3+ 145.Kxf3 Ke5 146.Kg4 Kf6 147.Kh5 Kg7 148.Kg5 Kf7 149.Kh6 Ke6 150.g4 Kf7 151.g5 Kg8 152.Kg6 Kf8 153.Kf6 Ke8 +- (1.89) Depth: 21/34 00:00:08 14768kN (, 18.10.2005) Uri
