In my opinion, Null move is rather: it is useless to try to live with one move,
if I cannot live by playing two moves of the same color in a row.

In my experiments, Null move enables to speed up by a factor of two
capturing problems search.

Any other one has measured the usefulness of Null Move
in their programs ?
