I think its 0%. its not that im being rude,, its just impossible. A guy rated 2500+ can still win a game even if he commits lots of blunders, although we can say that there will be very little chance for him to commit such blunder.
But, I can say, a guy with 1100 rating can still improve skills to a 2000+ rating level then beat those guys over 2500 rating in some other time.
Of course, I'm talking about games when both players want to win.
I also don't buy %0 percent chance, because I think I can get a win like 1 out of two million games.
Well i want to know, because i'm guessing my real life rating is 1100 something.
