In the past I played blitz on playchess, ICC and my highest rating there was greater on 150-200 than on chess.com .I think on chess.com the blitz rating of live chess is hard. Another explanation now I play worse. Who has some experience in this issue ?
ICC and playchess ratings might just be inflated. Depending upon the crowd that plays on a site, there will definitely be some discrepancies between sites. Or it could just be you warming up :)
