Go up one level in this thread


I found that I was not updating my smallboard when restoring a castleing move.
I fixed this and ran the 78 BWTC positions again.  The count is down to 496
mis-matches now.  I will disable some more code like en-passant and pawn
promotion to see if I might have code bugs there also.
