i think most or all do that for excample in the nullmove pruning. Do nullmove
for excample not in pure pawn endgames or if there are not a min. number of
pieces on the board.
See also the enhanced R2/3 nullmove pruning by Ernst A. Heinz where R depends an
the number of the pieces and the distance.

You can do such things also in other pruning techniques and also for search
extensions.
