Have you thought this: Let's assume that the 32-bit version gives 1 collision in every 5 seconds. Now, if you use 64-bit you get probably no collisions at all but you search 1% (or more, or less...) less nodes every second. Which is worse: searching a node and getting a wrong result or not searching those nodes at all?? Not searching might also mean "wrong result" in a sense and might result a wrong PV. And in case of 64-bit keys you will most likely miss more nodes than the 32-bit version actually collides. Just a thought based on speculation. Severi
