Actually, after looking at that post (which was quite useful), I'm not way off in my pre-flop play (for 6 max). I'm limping a little bit too much, but not a ton.

I am struggling with the right amount of post-flop aggression in raised pots when I have position but miss the flop and it's checked to me. In a SnG that's often a steal attempt, but these bloody calling stations that I run into just drive me nuts. They call with 2 overs, they call with ace high, etc. I need to adjust better and value bet them to death rather than using ill-advised aggression. I need to watch out for people who can't fold a hand.
