Hi Franz,

I suspect something wrong with the automated Chess-Master setup, about pawns: whatever position they are set to, a two squares move is enabled, as if they were still on their starting position. I assume the Chess-Master is using a different value code in RAM for a pawn which already moved?
Easy to test with editing a random position including boths kings and a single pawn, or check this funny move of the computer let to play from this position: 8/2k5/P1N5/8/8/6K1/8/8 w - - 0 1

Anyway much impressed by the hard work, much appreciated!
Eric
