Qe4 qxb6 Nf3 you play Qb8 Kg7 Rxf3 Qxf3. Even DIEP, despite white having a shitload of passers, already gets a near to draw score for that. White cannot move a piece except its queen. Rxg1 threatens each time and black has a knight to get to e2. At least black can already capture on g5, which i would never do as a human. easier is to jump some with the knight then go for mate :) This looks not a very good winning plan for white :) Basically the computers score gets dominated because white can give a lot of checks each time with its queen. If you do that, then it's a draw :) We call that horizon effect of a program. I guess you prune some of them. Not a good idea here. >> >>it takes diep a while to see that this is a draw. weird. looks >>trivial to me as long as you don't lose the d1 rook.
