Bit of fun this.
So, one time you beat player A. Another time, A beat B - who also has beaten C. C beat D, D . . . How long is that chain until you reach Player Z who beat Kasparov? Well, how long is, in fact, your Kasparov Number. And this is the website that will work it out for you.
For instance, Adam FF beat David Howell in 2001. Two years later, Howell beat Speelman - who had in 1996 beat Yermolinksy. And way back in 1975, Yermolinsky beat Kasparov. So Adam has a Kasparov Number of 4. Impressive!
Of course, not every Streatham & Brixton Chess Club player will be on Chessbase Megabase 2005, which IBeatGarry.com use to work out these degrees of separation. I'm not, for instance. But then I beat Antony Cullen earlier this year - and he's there, with a Kasparov Number of 6. So, my Kasparov Number is 7. Dang, I need to work on that!
What's your Kasparov Number?
