If this is the reason then I expect that at blitz Fritz can do better at engine-engine games but I did not see it. I also know that hash tables are not so important for fritz based on tests of mark young and fritz can do good results against most program even with only 1MB hash tables. I could understand a small difference in the result(if Hiarcs wins 9:7 in engine engine games and draw in regular games but I read better results for Hiarcs in engine-engine games) Uri
