Crafty plays Bb1, but the score is -1.19: > Black's position at this point is strong so there is not much chance now for white. Bb1 is the only move a strong human would consider as the "jailing" of the bishop is futile. Just an example of how computers sometimes lock in there pieces without appreciating the dire consequences. > 10 1:20 -1.19 1. Bb1 Bb4 2. Nfd2 f5 3. Nf6+ Kf7 4. > g5 axb2 5. Rxa5 Bxa5 6.

At depth 14, it gets worse, but >I don't know that it would play f3 in any reasonable time control because Rd3 >wins a pawn instantly at +1.x, while this is all positional king-side disruption >that takes longer to see...: This I think is the most interesting positions of the ones I posted. Yes it is a deeper type of position. It looks like black still wins by playing 3. ... Rd7 instead of Rxb8. Now the bishop is not allowed in for defense. White can squirm awhile but his king position is too compromised. Now after 3. ... Rd7 4.Rab1 g6! and white's bid for equality seems gone. > > 10 11.56 -0.26 2. d4 Re5 3. Qxe6 Rxe6 4. Rb8 Rxb8 > 5.
