Afaik the engine used during the "Fritzmark" is always Fritz5.32 - I think this one used to clear its hashtables between every move which probably hurts the performance in this test with very big tables. For real games: many(most)current engines don't clear hashtables between moves anymore - for those the bigger the better is a good rule ( as long as you avoid swapping), even in fast blitz games. pete
