There are millions of these positions for every program. I think that this information can reveal important details about weakness of the program. I also saw in the past a case when Tiger overevaluated supported passed pawns in a queen endgame. I believe that one of tiger's weaknesses is overevaluating passed pawns in the 7th. It seems to imagine that they are promoted if there is a threat to promote them in the next move and it seems wrong. Uri
