I've cut and pasted your data to follow mine for each position. I don't count the number of probes I do.. maybe I should. Anyway, on positions 1 and 3 I noticed your fail high% is significantly higher than mine. On position 2, my fail low% is significantly higher than yours. Position 2 is more "tactical". How do you interpret that? Is it likely that I have a bug, or is this a consequence of poor (or different) move ordering? My move ordering is horrible right now... but I'm not sure how that affects my hash table usage. BTW - I'm using a combination of depth preferred and always replace. The "tables" are the same size (really one big table so I can do consecutive reads). -- James
