I do not know. I also do not understand the position. Can you show me errors of the top programs when you play against them. If mobility is not important there then I need exact definitions to explain it. I suspect that pawns in the centre is not enough and there may be positions when mobility is more important. What if you give white only one tempo [D]rnbqkb1r/pp1np1pp/4p3/2pp4/3P4/2N2N2/PPP2PPP/R1BQKB1R w KQkq - 0 6 > >[D] rnbqkb1r/pp1np1pp/4p3/2pp4/3P4/2N5/PPP2PPP/R1BQKBNR w KQkq - 0 6 > >Shredder 7.04 depth 1/2 (0.41) >Ruffian 1.01 depth 1/2 (-0.71) >Crafty 19.03 depth 1/7 (-0.32) >Yace Paderborn depth 1 (-0.44) > >[D] rn1qk2r/ppbnpbpp/4p3/2pp4/3P4/2N5/PPP2PPP/R1BQKBNR w KQkq - 0 6 > >Shredder 7.04 depth 1/2 (-0.49) >Ruffian 1.01 depth 1/2 (-1.01) >Crafty 19.03 depth 1/8 (-0.69) >Yace Paderborn depth 1 (-0.83) > >Difference: > >Shredder 7.04 0.92 >Ruffian 1.01 0.32 >Crafty 19.03 0.37 >Yace Paderborn 0.39 > >Michael Latest Movei agree with Shredder Movei scores are dependent not only on the leaf position and they may be wrong at depth 1 so here is comparison at depth 2: +0.31 for the first position -0.66 for the second position depth 7: +0.30 for the first position -0.66 for the second position Uri
