This can be a problem. You can store a signature for null moves in the HT (for
example a special move, say one that is always impossible like a1-d2). At the
time you probe the HT and want to do a cutoff, and the stored move is a null
move, check if in this situation a null move is allowed. If no, ignore the HT
entry.
