Yes that was me. Surely this is advantageous for two reasons. Firstly, playing stronger players improves your game, and secondly, if you win, your rating increases faster than playing same or lower rated players. I`m not really sure what provisional rating has to do with this. Some provisional rated players may have been playing for years before joining the site, and be quite capable of playing a reasonable game against a player with a higher rating. Having a provisional rating of 1200 is therefore meaningless in terms of playing ability.
