It's tiny things really, like I had a GenCastleMoves which was called from GenMoves. In GenCastleMoves I checked the flag first, most of the time this flag isn't set so castle is illegal and I can return, it's just a function call overhead for nothing. Actually I would like full inlining here, to have GenMoves and GetNextMove inlined in my Search. But if I understood things correctly, I would then need to have all the code in one huge file. I don't want that. -S.
