I have run several thousands games with Rebel8/9 with auto232 and never seen
anything strange. However for me it is clear that Rebel8/9 plays clearly better
with 28mb hash than 60mb (2h/40) on a "slow" computer like P200MMX. It is
both slower and can play weaker moves with 60mb hash. The manual or helpfile
should include recommendations for hash/time vs computer. For instance on faster
time-controls CM6000 plays better with small hash-tables. Mr de Koning said
that 16mb was more than enough for his program in 2h/40. He also recommended
smaller tables for speed-chess.
