As you stated Uri, 20 points, that is'nt much. I also noticed Deep Fritz often likes to swap down to an endgame and this has backfired on Deep Fritz, as it plays the endgame I feel only marginally better than Fritz6e, in some cases not as well! If you want or actually need Deep Fritz over Fritz6e then you would be wise to buy a dual cpu or even up to 8 if your budget allows, for such a beast. On a duel cpu I'd wager it's between 50 and 60 ELO points, stronger than a single. As you increase the number of cpu's it will continue to rise but more slowly, maybe 8 cpus it would rise up 150 rating points. Maybe? Terry McCracken
