I did find one bug though, the knight tables were being multiplied with a factor 5, I forgot all about that. It was just a quick test to adjust all piece square scores at once, but seems I forgot to remove it, no wonder evaluation was off. However I now found a new bug! I have turned off everything, killers, hashtable, nullmove, using only material eval and I get this 1 0 0 3 1.dxe5 Bxe5 2 0 0 79 1.dxe5 Bxe5 3 0 1 521 1.dxe5 Bxe5 2.Rb1 4 165 1 3608 1.dxe5 Nb3 5 335 4 22022 1.dxe5 e4 6 380 11 81855 1.dxe5 Nf3 7 435 43 373682 1.dxe5 e4 8 165 284 2628534 1.dxe5 e4 9 165 986 9151622 1.dxe5 e4 white is better by up to 4.35 pawns and dxe5 Nf3 is illegal. I dont know what is going on here.... -S.
