If you don't handle repetitions, the humans won't figure this out for a while, but once they do, watch out. And before they figure it out and start exploiting it like crazy, you'll still draw games where you are a rook up and winning effortlessly. Having this stuff in the search allows for some pruning. I don't know if the amount is significant, but as a side-effect, I'll take it. Detecting reps in the search has to be significant tactically, since there are so many positions where perpetual check is an issue. I may not have answered your question. bruce
