[D]4b3/6p1/5p1p/5P1P/3kPK2/1p6/1P2B3/8 b - - 0 1 My engine just managed to lose what looked like a dead-drawn endgame against a Crafty clone on ICC. I couldn't understand what happened. I still don't know exactly, but it looks like some kind of hashing/draw-by-rep/nullmove artifact ;) But my program doesn't seem to be the only one that gets funny on this position: Analysis by Fritz 7: 80...Bf7! ³ (-0.69) Depth: 12/20 00:00:00 316kN 80...Ba4! µ (-0.72) Depth: 12/20 00:00:00 550kN 80...Ba4-- ³ (-0.44) Depth: 13/16 00:00:00 574kN 80...Ba4 ³ (-0.44) Depth: 13/21 00:00:00 630kN 80...Bf7! ³ (-0.47) Depth: 13/21 00:00:01 856kN 80...Bf7! ³ (-0.63) Depth: 13/21 00:00:01 989kN 80...Bf7-- ³ (-0.34) Depth: 14/17 00:00:01 1040kN 80...Bf7 ³ (-0.34) Depth: 14/19 00:00:01 1089kN 80...Ba4! ³ (-0.38) Depth: 14/24 00:00:02 1705kN 80...Ba4! ³ (-0.66) Depth: 15/26 00:00:03 3200kN 80...Bf7! ³ (-0.69) Depth: 15/26 00:00:05 4577kN, tb=1 80...Bf7-- ³ (-0.41) Depth: 16/19 00:00:05 4778kN, tb=1 80...Bf7 ³ (-0.41) Depth: 16/23 00:00:05 4941kN, tb=2 80...Ba4! ³ (-0.44) Depth: 16/29 00:00:07 6732kN, tb=4 80...Ba4! ³ (-0.59) Depth: 16/29 00:00:08 7756kN, tb=5 80...Ba4-- ³ (-0.31) Depth: 17/19 00:00:09 8090kN, tb=5 80...Ba4 ³ (-0.31) Depth: 17/23 00:00:09 8349kN, tb=5 80...Ba4! ³ (-0.59) Depth: 18/33 00:00:25 22724kN, tb=94 80...Ba4! µ (-0.88) Depth: 19/36 00:00:53 46904kN, tb=333 80...Ba4-- ³ (-0.59) Depth: 20/29 00:00:56 49294kN, tb=344 80...Ba4 ³ (-0.59) Depth: 20/29 00:00:58 50834kN, tb=345 [etc] (Pascutto, Gent 20.09.2002) -- GCP
