The position didn't occur in the first game. All I'm tring to say is that two "nodes" really aren't identical unless the 50-move counter is the same, and the positions between where you are and the last non-reversible move are the same (although they can occur in different order). Of course, the castling flags and en-passant legality need to be the same, too. bruce
