Ais,
I have been playing n Stars for the last 15K hands and the games are very tight. As you know tight doesnt mean good. For the most part, they are bad post flop. My stakes are 50 and 100NL and I have to admit they are btter than most other sites, better meaningyou can extract less from them than avg. pl,ayers in other sites.
My adjustments have been limping more hands (VP$IP from 12% to 15-16%,) more preflop raises (from 2% to 4-5%), Contnuation bets even when I missed and it didnt narrow the field (for instance when I raise preflop in Party and the flop comes QJ2 with two spades and there were three callers, I check behind if possible, in stars, i bet and i take it down very very often.
Idint remember the results I've got where in Absolute Poker, very well known for being a rock garden. It seems that it suits my playing style playing the rocks. It also feels great to have the abslute control of the tables. Also, a lower winrate could be acceptable if it's for lower variance and a more active entertaining game.
