I was misthinking! But in the above mentionned game it did sacrifice a pawn to avoid it too! Anyway I ended up losing by the time! I was not fast enough to play moves in 0 seconds and when it sacrificed the pawn to avoid it and when it happens I took with the wrong pawn (no time to figure everything) and got into trouble, anyway. I think the "contempt" factor was not set to favor draws or maybe I misplaced a piece so a break had become possible. My point was just to say that it is unfair that a program could play any number of moves without even thinking ONE SECOND. It is impossible for Genius (don't know about Genius 5) to lose by the time. When it has 0 time left, it start to play instantly without taking any time. So even if it misused its thinking time, it has no penalty for doing so, since it can play an infinite number of moves at 0 second left, still thinking on your time. And the "operator time" had no effect over it! Serge Desmarais
