SL-Mark: I see your point. Its matter of luck:) From this reason there are these new ratings provisional. I am not familiar with USCF ratings, because Czech chess federation is using ELO system (same as FIDE). But also in this system it is similiar - with difference your rating is provisional until you finished 9 (or more -it depends on how many games you play during period in which is rating calculated) games and from these games is you rating counted. It is better to defeat higher rated players in the very begining your career. But it is not good for internet ratings where change must be visible after finishing every game, not after some period.
Rating 1300 is used when two players without any finished game meet each other. If you finish first game, you still see non rated, but system is using your new rating.
(nascondi) Se vuoi giocare contro un avversario del tuo livello, puoi definire un BKR minimo ed uno massimo per ogni nuova partita che intendi creare. In questo modo nessun giocatore che non sia all'interno di questa fascia di rating potrà vedere o accettare il tuo invito. (Katechka) (mostra tutti i suggerimenti)
