I have a special function for perft.
removing pruning or extension will give the perft command only if you do not use
alphabeta and I suspect that programmers need to change some code for that
purpose and removing lines is not enough(I have return alpha or return beta in
my code and I probably need to change to fail soft if I want to calculate perft
by removing code).
