I also think that there is a logarthmic increase in performance with more ram in the TT. In other words, from 64M to 128M will give a much better performance benefit than from 128 to 256M, and that will be much better than 256M to 512M. So at some point, you will clearly be better off to put information in the EGTB cache instead of hash tables. Also, if you play the horrible chess-like game of blitz, it may be expensive clearing the table, and having a broad hash will result in a lot of cache misses -- a *very* expensive operation on the newer intel type architectures. Hash is clearly more important than EGTB cache (I think Deiter's experiment bore that out). But I think if you have 10 gigs of ram, how to dole it out would take some experimentation at the desired time controls.
