I think it has more to do with style, I imagine the score differences are minute and a single tiny evaluation term can be critical for liking the move or not. >r4rk1/pp1n1pp1/2pbpn1p/q2p3b/8/PP1PPNPP/1BPN1PB1/R3QRK1 b - - 0 12 > >Once again Zappa wants e5. Deep Blue played Bc7, which is a pass move at best, >and I would think the bishop is actually better on D6. Yes that's one of those typical "ugly" computer moves, it seems a bit pointless unless DB wanted to transfer the bishop to b6 or something. But again in a position where there are no obvious best moves and it's all about style it's not easy to point fingers. >1... e6-e5 2. c2-c4 Qa5-a6 3. d3-d4 e5-e4 4. Nf3-h4 Ra8-e8 5.

Agreed, so far I haven't seen any conclusive evidence to tip the scale either way. Speculation is fun of course, but it will only take us so far. -S. >anthony
