Hi Robert, Vincent Lejeune posted a message on June 01, 2000 at 5:42:33 that said to download Crafty and use the 'perft' command to get the possible moves at 'n' plies. The message contained... White(1): perft 1 total moves=20 White(1): perft 2 total moves=400 White(1): perft 3 total moves=8902 White(1): perft 4 total moves=197281 White(1): perft 5 total moves=4865609 I assumed that this produced all the legal moves at each ply level and was using it to validate counts in my program. I matched the 197281 until I added en-passant and now I get 197303 at ply 4. Does your perft command do enpassant, castleing etc? Larry.
