From what I can tell, you may be overplaying your good starting hands after the flop. Take that AK for example. When the flop came out 3 clubs, make a small bet to see if your opponent has it, if he does, fold. It's just AK. With AK you're going to miss the flop 3 out of 4 times anyway. Just cause a hand is good to start off doesn't mean it's going to pay. Unless people fold right then and there. It can be hard, but in NO LIMIT you have to be able to let go of good STARTING hands that don't hit-- unless you're REALLY good at post flop play.

Sounds like you played the T6 correctly.
