The CD containing info about Hiarcs actually states Fritz, and I believe the manual is flawed. It isn't clear to me why they begin the manual with Fritz at the headng. I find it very difficult to believe Hiarcs uses the same formula for HT requirements as Fritz. I requested information on this matter from Chessbase and am awaiting a response to this and other questions.

Is Hiarcs 7.32 very smart with hashtable memory? > >Eran
