I played a player who has almost a 700 score. I won the first game, but got crushed the next 2 games. I checked my History of my games. It showed me 0-2 against that player. Checked his history, it showed him 2-0 against me. It never recorded my win against that player. So, it must have been a player with a program, who plays for this web site. Probably the reason it did not record the loss.
