Hi, all. I saw several discussions in the past on hash table replacing schemes, optimal hash table sizes, wich information to store there, etc. But I don't remember any discussion about what positions are the best candidates to store in the HT. What most of us do is to store positions in wich the best move is a fail high or, an exact score, wich is correct for move ordering purposes. I was wondering if someone uses a different criteria for choosing positions to store in the HT. When in some middle game positions I see a drop in the hash table hits (below 15%) of my engine I sometimes think if there is a better way to improve the transposition effect, if such a thing can be done. My best, Alvaro Cardoso
