Sorry , but I don't believe this. Can you set up a position and benchmark the eval/ply/score and I will do the same with MY fritz ? Could we take the commercial one to make sure we all use the same engine ? I cannot believe this. Sorry. >- Fritz with e.g. 2 MB hash tables is 3-4 times slower at 40/120 than >Fritz with 100 MB hash tables (which also get sometimes 100% filled on >my P166 at 40/120 time control). Thorsten knows about this, of course >;-) Right. Fritz5 needs big hash. So buy it. And use it. But I will not buy extra hash-tables only for fritz5 when I don't like have the right feeling to do it. Let Feist/Wuellenweber or Moritz buy huge hash-ram. If they have the right feeling, they should do it than. >-> Hiarcs is quite insensitive to less hash tables, also when you use >e.g. Hiarcs 6/DOS on a 16MB RAM machine you get 15 MB HT, with Fritz 5 >on the same machine (Windows also takes some RAM, add some for the >graphical user interface ...) you will maybe get 1 MB HT). Ohhhh ! Thats not my problem, or ? I would say: this is ineffective programming of the Fritz-development-team ! I have tears in my eyes now ... :-) > >- Opening books: Fritz 5 comes with old (throw-away) .FBK books and a >(small, too shallow for comp. vs. comp. games) 100 MB opening tree on CD >which is not optimized for play vs. other programs. They sell a program with an opening book that is only good to throw it away ? I would say this is not my problem too.

Manipulation ? I shall by a program to play chess. It comes with a shit opening book, needs 256 MegaByte RAM to run almost efficient, needs 600 MegaByte HD and your powerbook tree to run half-way strong and you call anybody NOT doing your senseless efforts MANIPULATING ! That is strong ! I had similar threads about crafty ! Guys - you have a problem. Your programs need too many resources. Hiarcs runs very good with 16MByte RAM and 650 Kilobyte HD-space ! >My advice therefore is: Never trust results where the poster doesn't >quote at least: >- CPU used >- RAM allocated for hash tables >- book settings (book type, learning enabled?, book source, ...) >- maybe also some figure like "it takes 20 seconds from initial position >with fixed depth 8 ply to play 1.e4" to verify the correct speed of >other components (2nd level cache, RAM settings and type (EDO, SDRAM, >...)). maybe we have also to post a picture of our girl friend to satisfy you ? Moritz. This is really ... hm... unbelievable. I would call your behaviour a little hardware-materialistic and freaky ! I don't want to be a freak ! I love chess. I love computerchess. But I am not running through the town with a soldering iron and modules-of-ram in my trousers. Also I will not turn arround only because there is a computershop or McDonalds. I turn arround if there is a nice girl or La Tour Eiffel, but not for a computershop. > >It's all slightly technical and complicated, but without sufficient >information you are ill advised to believe *any* results of the >aforementioned kind. Maybe ChessBase should sell a special Fritz5 for Freaks development Kit with 500 MByte Ram, a fireball 3 GigaByte HD, a Gigabyte main-board and a Hamburger from MCDonalds ! :-) > >Moritz > >P.S.: Fritz 4.01 with 64 MB hash tables vs. Hiarcs 6 (Fritz-Engine) with >32 MB hash tables on P166 with Fritz4.fbk and reversed colours from the >same opening: > >result: Fritz got 52% out of 40 games 40/120 with permanent brain >disabled.
