I suspect that the score of Krnp vs Kr of chess tiger is bigger so the fact that it is more easy to win does not say that the evaluation is wrong. Chesstiger did not like kramnik's moves so the fact that the game was drawn does not prove that the evaluation was wrong. The question is if chesstiger can win other programs. Uri
