It simply read the first move from the CD and if it is wrong then it is losing the game. It is the case with Fritz5 and I read that the same is with fritz5.32 I am sure that fritz can find the right move without the CD but chessbase decided to use the CD and it is their problem. Fritz could probably have better rating without the CD because in most of the cases it can find the right move in simple endgames by regular search. Uri
