Everybody uses nowadays additional pruning. Otherwise the big search-depths
would not be possible. Hydra uses them too. But so far not History-Pruning. Did
not work with the other pruning techniques.
The kind of pruning is a secret. One big error - publishing NullMove - is
enough. But NullMove was anyway known in the community.
