But that is a close >approximation, particularly at 2300 and up... Not really. I have between 24xx and 25xx myself at ICC myself, and when i play blitz. Americans with an USCF rating they positionally play like a beginner, to put it in an understatement, when i compare that rating to what an european player moves with such a rating. So usually i'm very happy to play an American! Weird that there are so many IM's at ICC which play positionally like ****, where **** is something which smells. And it's good to know that here in Netherlands they describe my style as being effective but not too positional. For players above 2500 rating usually becomes very accurate at ICC server. Ratings below this are very inaccurate. And i believe that the lower a rating gets, the bigger the difference x. in USCF = FIDE + x For example 2200 USCF players i'd usually give 1800, and 2400 players more like 2200.
