Subject: Detecting three-fold repetition?

I've had a number of requests to implement 3-fold repetition detection in TSCP.
It's also clear that TSCP would do better in tournaments (although that isn't
the goal...) if it could detect these draws.

So the question is, is there an easy way to do the detection?

In my "strong" program, I just compare hash keys. But TSCP doesn't keep hash
keys and I have no intention for it to do so. So is there another way to do it?

Thanks in advance.
