I noticed I get greedy on a lot of turns and try to fold them if a c-bet or semi-bluff gets called and then checked to me again heads up. Yea - this has to be a leak!

hmmm, the second hand...still not sure what a better line would be. Gotta bet the flop, right? He could have a weaker pair, an OESD, or hes bluffing syndrome with AJ+ (Ive seen that quite a bit). But then what on the turn? I usually do a 1/2 pot bet to try to manage the pot.

At the river there's pretty much 1-2 hands (QQ or AJ) I beat, and a bunch that kill me. I think a check and calling a small bet on the river wouldve been better. But would anyone check the turn or maybe even the flop?
