I'm not here to say diep is holy. I just point out here (although i thought Seirawan had already done it enough it must be hammered in some minds before they can think about it) how horrible it plays. Diep's not the only pc program not playing b5? you know! You better get ashamed when your program is playing it after long thinking. Now for piece square table programs like Nimzo and chesstigre i guess this is gonna be hard for you. > Christophe
