Just keep in mind that you haveto pick the positions before you see how the rest of the game turns out. I think we can agree that there is no limit to how much an opening book is worth if you know exactly what will happen :) Actually in this case you'd pick .. Bd6 because Crafty is well-suited to defending against the particular king attack which it will provoked there. :) > >The Sjeng-Crafty game of round 2 had a strong influence on opening choices of >opponents, because they realized that Crafty was ready and willing to discuss >the Berlin endgame.

It's a fine line IMHO, but Crafty hated the bishop on d6 so much that it >couldn't think of anything else than getting rid of it ASAP - LOL .

It seems that often the engines will get away with it. One thing I agree with - the Berlin is not at all drawish - at least when Kramnik is not involved ... :) Vas >Peter
