Just by curiousity, does null-move or other threats detection techniques work
for checkers?
I know it does not work in Othello/Reversi because zugzwang positions happen all
the time, but I suppose this is not the case in checkers?
Can you tell us about selection techniques that work in checkers but do not
apply to chess?
Just curious, I'm not planning to write any non-chess game playing program. I
went directly from tic-tac-toe to chess in the early '80s!
