Shouldn't apart from the side to move also the current step number be part of the Zobrist hashing key?

Along with pieces and side to move I include steps left, if it's in the middle of a push and the last piece to move. If pushes and pulls are done as one operation, instead of two separate steps, the last two aren't needed.

Also relevant to include, possibly, would be how many times this position has occurred in history leading up to the current state, for purposes of evaluating repetition.
