The 2650 you mention is USCF. Check out the players. USCF (at the top) is typically no more than 50 points above FIDE. Ken Sloan has a detailed list on his web page in the department here... and he did a lot of analysis to correlate FIDE to USCF. the +100 or more is generally wrong. > >>With the above data, how far _ahead_ of Rebel (in terms of time) would you say >>DB-2 is?
