This may be the source of my confusion -> Did you mean A) use the main
transposition hash table to detect repetitions, or B) use a seperate, smaller
hash table to detect repetitions, as Bruce does in Gerbil?

I assumed you meant A (not sure why), but I use B. I think that by using a small
hash table, you are safe. Even if there are 600 positions that occured in the
game, if you use a 64-bit key, that is...gosh, really good odds :)
