He doesn't want to use 'if' clauses to do it, because they add instructions (supposedly slowing the program down). How else would you suggest to do it simply, other than cut/paste? Note that his current solution (separate exe files, one for games and one for perft) is cut-and-paste of the entire program, not just a couple functions. :) But, now that I think about it, Uri really should try just using simple 'if' clauses. The branch predictor should be almost perfectly accurate there, meaning that there will be negligible speed loss due to extra comparisons.
