I wouldn't worry if this occurs in one or two test positions, although it are seldom exceptions when negative effects of larger hash size are noticable (I think programmers can tell this better). But in general, or in average for a higher number of test positions, larger hash size must be an advantage especially for Fritz and other programs with such a high node rate - under the condition, that the larger hash is utilized (this means, the tests are so difficult, that the solution takes long enough to fill more than the smaller size you compare with). Furthermore it may be necessary to delete the hash tables (content) between the test; see engine dialogue box... I'm not sure if Fritz 6 would keep the hash data even if a new position is loaded. Maybe this affects your results too. Regards, M.Scheidl
