I've been testing an idea for pruning or aborting a search in the middle of the movelist on a given node. I am not sure if this is a new idea... In fact, it is so simple, I would be surprised if it is new. A quick search of the chess progamming wiki shows a similar idea, "uncertainty cutoffs", which is more precise about when to terminate a node. The idea I tested makes no use of uncertainty and simply makes the decision of whether to abort based on position in the movelist.

I think this is called Late Move Pruning (LMP) or Move Count Based Pruning. Here is a long thread on it.
