I'm better, of course!
But in all seriousness, this is a question that will be debated until the end of time. Just about everyone can agree that Kasparov and the real Fischer are the 2 greatest chess players of all-time, but there is no consensus on who is better. If you're judging strictly by accomplishments, then Kasparov is better because he held the title for 15 years and took part in 8 World Championship matches. But then again, all one has to do is look at Fischer's brilliant games to see that he has a rightful claim as well.
Who's better? Who knows?!?
Being someone who doesent have the greatest chess history knowledge. I would lilke to know some opinions on who was the better of the two well known grandmasters.
