[D]2r2rk1/1p2bppp/1qn1p3/p2pPn2/1P1P1P1P/P2Q1NP1/1B2N3/2R1K2R w K - This position was reached in a game on ICC, with LambChop black and a human white. LambChop just played a5, which allows the opponent to attack on the king side with g4 Nh6 Ng5 g6 h5 and white is winning I think. I was a little surprised that it takes Chop 11ply to play g4 (initially it preferred b5), and even after a 13ply search the score is still slightly negative (0.2 in black's favour). So I'm wondering how other programs do here? I think that black has some chances to muddy the waters with sacrifices on b4 at various points. While I don't think these are any good, they do have some merit and could push the horizon out a bit. Any suggestions of what sort of evaluation terms or extensions might help here would be welcome :-) cheers, Peter p.s. Now I see that there is another possible defence: g4 axb4 gxf5 bxa3, not sure if this works but it's interesting. The position after g4: [D]2r2rk1/1p2bppp/1qn1p3/p2pPn2/1P1P1PPP/P2Q1N2/1B2N3/2R1K2R b K - In this position, Chop needs 12ply to switch to axb4, score is +0.44. I wouldn't treat that score as gospel, but I think axb4 is a much better try than Nh6.
