Hi Sarah
In my opinion your assumption is not correct.
You could test this by comparing 120'/40 64 MB hash
and 30m/game 64 MB hash and 120'/40 64 MB hash with
120'/40 and 256/512 MB hash. Search depth of moves
with 64 MB will hardly be different to 256/512 MB
hash but in any case much higher than a 30m/game with
512 MB hash. According to my tests, the importance
of hash size is much overestimated.
