If you go straight to the position without Fritz having the gamescore it finds Qe6+ at once. I do not know if Fritz looks at the hash to see draws but that is pretty probable. Anyway I think its easy to spot the reason for this "bug". Fritz and a lot of other programs gives the second repetition the score 0.00 even if the side with the advantage can vary next move with a big advantage. Torstein
