Optimize an expression in endgame.cpp I believe using foward_file_bb() here is fewer instructions. a) Fewer instructions and probably more clear (debatable). b) Possible that a lookup is slower than a few local operations, but the forward_file_bb table is probably used often enough that it is always cached.
