My hashtable implementation has separate tables for white and black, and a part of each of these tables is depth prioritized. This works ok in general I think. But I notice that Crafty for one, uses one table, and then inverses the hashkey in case of probes and stores, when it's black to move. There may be other implementations as well. What are the pros and cons of these approaches, and specifically, why does Crafty invert the hashkeys in the case of black to move, instead of just hashing the color into the hashkey? /David (who is deparately trying to find a possible hashing bug in Chezzz...)
