Up to version 4, "Fritz" definitely did it ... Fritz3 didn't do it. If it misses a move, you make some moves after which it sees the critical part of the variation then you take back, then you already see clearly that it didn't clean hashtable. Easy. Perhaps 4 messed up because that was a windows experiment. >Where do you get your knowledge from?

Did you test positions at it and then try to see whether it learns from its hashtable? Frans ain't stupid of course he profits already for years from this not cleaning hash. In diep it speeds up in middlegame at blitz more than 30%, but at slower levels less. Endgame weirdly not more than this 30%, i would expect more, but this ain't the case. Rebel needs to clean them, and i leave it to you why it needs to, because i get otherwise another 20 stupid hatemails from guys knowing shit of computerchess. >=Ernst=
