Thanks for the info.  Am surprised to hear that Crafty and Fritz6a have some
trouble.  Crafty in particular must be doing something wrong not to see this.

Nice to see Grok playing again.  Re those king moves, I thought that was some
sort of new attack scheme you were trying.  Happened in a couple of the 4 games.
 Sorry to hear it was just a bug :)

An older version of Amateur will take the pawn.  The new one seems to like the
fact that your pawns are bad, and wants to leave them that way!  So I have some
adjusting to do.
