Size of hash tables seem to have much less influence
than I have imagined. This showed a test over 50 games
between Fritz 8 [96 MB hash] against Junior 8 [8 MB hash]
and a second 50 games match Fritz 8 [8 MB hash] vs Junior 8
[96 MB hash]. The final result was in both matches almost
identical [25m+10s].
