I agree with Batgirl's last statement; if a tournament did allow analysis boards, any rating resulting would need to be dissallowed from 'normal' chess ranking. Because one would expect players would play above their level with the electronic assist, they would have an inherent advantage over all other players in all other tounaments without them. After all, it wouldn't be very fair to claim someone set a swimming record in the 100m front crawl if they were wearing swim fins, would it? (Not that I know enough about swimming to know if that would even help, but you get the idea.)
I guess that's the main difference between my argument about the calculator in the math exam and chess; one is competitive and weighted against all participants worldwide, and the other is only weighted within a small controlled population. Still, if it were clearly designed to be a separate event, it might have appeal to certain players over the original. After all, the only real human race is a foot race or a swimming race without assistance. Still, auto racing, boat racing, and a score of other '-assisted' races are incredibly popular because they add elements not seen in races where the unassisted human being alone is involved.
Kasparov, at least at one time, championed the idea of using computers in tournament/match play. I never appreciated the rationale. The idea, at least at high levels, is to rid the player of some of the donkey work of computing variations and doing blunder checks so he can spend more time on the other parts of the game.
*Shrug*
Computing variations is part of the game. A person should take responsibility for every aspect of his/her own game. Then again, I think professional golfers should carry their own golf bags, race car divers should change their own tires, politicians should write their own speeches and musicians should never lip-synch.
If some folks wanna have a computer-assisted tournament, then it should be a separate thing with its own ratings.
