So I went on the net with The King running alone on my system to better judge its performance against some competitors.CM6000 would almost always get crushed by Fritz 6a.CM8000 has a plus record against Fritz6x even for 5 games against someone with twice my hardware.Which thrilled me to death. Then last night on Yahoo I played 5 games against CM7000 and came out ahead 1 ,but there were two draws where CM7000 was ahead on material and The King barely escaped with a draw I was disturbed by this because Fritz will beat CM7000 most times convincingly. Results are still erratic and many tourneys and matches will be necessary to determine ultimate strength. I do know large hash (32MB)? is much weaker at less than 15 min. games. My overall impression strengthwise is that the other latest programs Tiger 13, Shredder 5,Fritz 7? are probably stronger but obviously not as feature packed. This is a subjective opinion, not objective because I do not own the other progs as of this date.It is based on what results and comments I have seen here and elsewhere on the web. Regards,Paul
