I think the turn aggro is a very good point. I had a tendency to give up a little too much on the turn, sometimes becoming a calling station. Good players will exploit your "c-bet and shutdown on the turn" pattern as well. I don't recommend firing a lot of turns with garbage/air, but if I felt my hand was good on the flop, I'm betting it on the turn regardless of what comes UNLESS I chk behind for pot control (basically saying I try to avoid calling so many turns). This also makes it easier to find out if you're behind and get away from the hand.
So, if he went more aggro on the turn, it makes sense for his wtsd to decrease a bit b/c he should have a better idea where he stands after the turn bet if he doesn't take it down.
At least this all seems makes sense in my head? My increased aggression was going pretty well until my asstacular session this morning.
I don't agree with c-betting 100% though. It's spew, imo.
