yeah, step down for short periods if you need to gain confidence, but I didnt find too much of a transition from $25NL to $50NL, though it is a bigger jump than to $100NL, which is pretty damn fishy if you ask me. But aisle is right, solid, and aggressive poker is the way to go. For example, I'd never limp AQs is a 5/6max game, SB or not. In fact, at places like stars, where I find the players to be weak/tight, if somebody open-raises, I might bump it up to 12-15x pf (depending on the player of course) and hope for a laydown (happens often). But play your good holdings... that's about it. I didn't find the players to be overly sophisticated at 50NL, it's very possible that they have the goods, and aren't putting some plays on you.
