I've generally had success at those kind of tables staying pretty tight in EP and MP but loosening up quite a bit in LP -- on the button, in the cutoff and somewhat in cutoff+1 -- and blind-stealing like crazy with anything that'll give you some decent outs in case of a call or a reraise. Really, most any PP, any A down to about A6 and just about any hand where the lowest card is a 9 if it's been folded around to you.

If there's a limper or two ahead of me, I'll still go ahead and raise with AJ or a suited QJ or some more marginal hands that could be strong with a decent flop.

I generally don't slowplay anything short of a flopped full house because I don't like to take a chance of giving out free cards to any decent draw I might be up against. I'll go ahead and lead out or raise if I flop a set or two pair or something that people tend to want to slowplay until the turn. I think you want to take down a pot as soon as possible with anything that's vulnerable to a decent draw.

The key is to be able to get away from some decent hands if you sense trouble. Being able to lay down top pair/weak kicker or draws without decent pot odds is key to not getting eaten alive at those kinds of tables.

Play the river better than them.
