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.
