The U.S. Amateur Team East, which will be played over president's day weekend,
offers a "best upset" prize.  The winner is usually a 700-800 upset, but it's
usually a 1000 rated kid who beats a 1700-1800.  There are probably on the order
of 2500 games played.  I remember seeing something in Chess Life a few years
back where an A-player beat Lev Alburt, possibly when he was U.S. champion.  I
think upset draws are much more than twice as likely as upset wins, but we don't
hear about them as much.
