This is my perft() suite run on a P4 1.8 GHz on Windows 2000. This is the same code used by the engine: a pseudo-legal move generator which also updates evaluation variables, detects checks and so on. It's hardly an optimized implementation though. perft: depth=6, FEN=rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1 perft: depth=1, nodes=20 perft: depth=2, nodes=400 perft: depth=3, nodes=8902 perft: depth=4, nodes=197281 perft: depth=5, nodes=4865609 perft: depth=6, nodes=119060324 perft: total=124132536 nodes in 25.687 seconds (4832 KNps) perft: depth=5, FEN=r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq - perft: depth=1, nodes=48 perft: depth=2, nodes=2039 perft: depth=3, nodes=97862 perft: depth=4, nodes=4085603 perft: depth=5, nodes=193690690 perft: total=197876242 nodes in 42.375 seconds (4669 KNps) perft: depth=6, FEN=8/PPP4k/8/8/8/8/4Kppp/8 w - - perft: depth=1, nodes=18 perft: depth=2, nodes=290 perft: depth=3, nodes=5044 perft: depth=4, nodes=89363 perft: depth=5, nodes=1745545 perft: depth=6, nodes=34336777 perft: total=36177037 nodes in 8.157 seconds (4435 KNps) perft: depth=6, FEN=8/2p5/3p4/KP5r/1R3p1k/8/4P1P1/8 w - - perft: depth=1, nodes=14 perft: depth=2, nodes=191 perft: depth=3, nodes=2812 perft: depth=4, nodes=43238 perft: depth=5, nodes=674624 perft: depth=6, nodes=11030083 perft: total=11750962 nodes in 2.593 seconds (4531 KNps)
