In a Principal variation search, what type of "useful +elo" pruning do you use at PV-nodes ?

I do no pruning at PV nodes, only reductions.

Late move pruning
SEE pruning
History pruning

Almost everything that works in the cut and all nodes works in pv nodes but are less important because pv nodes are very few.
