Source square? Destination square? I may be >able to help you... With bitboards (as I'm sure you know) you need a piece of assembler using bsf, then you need to clear the bit afterwards. This is not needed with 0x88. ie: while (padvances2) { to=FirstOne(padvances2); *move++=(to+16)|(to<<6)|(pawn<<12); Clear(to,padvances2); } >When using bitboards and looking for a pattern instance for a _single_ square, >think again : You should be looking for pattern instances on _all_ squares >simulataneously. Right, I get the idea :) -S. >Puzzled, >Steffan
