Subject: Problem with draws by rep and hash table

My search currently decides a position is drawn if it has repeated twice. I
think this is causing my search to sometimes stuff 2nd rep draw values into the
hash table that can be retrieved for positions with different history's. Is this
a problem? What do other people do? Could I just not store any draw values in
the hash table? Should I go to draw by 3rd rep?
