edit: oops didn't see it was done. And I'm pretty sure I could beat an IM down a knight. Definitely if he's down a rook. And I'm not very good.
If you're truly "not very good", how can you have any idea what it takes to beat somebody who is very, very good, and therefore how would you know what handicap is fair? Or did you not bother reading the rest of the thread, and notice that durrrr lost a bit of money because he thought the same thing?
I am a huge fav. against Durrr. I am extremely good at chess compared to the average nonstudying player and better than a lot of players who have been playing and studying for a while. Still nowhere near someone like Curtains though.
