The big note is to not C-bet this flop. The generally good rule is when you have a PP and there's a higher card on the board, i.e. QQ with a King out there or KK with an Ace on the board, do not c-bet. You're over-repping your hand and will often be called by a lot of hands that beat you.

This is why you got so confused on later streets because you had no idea where you stood. So don't cbet the flop, c/c flop, c/c turn and see what happens on the river. But when you play a second pair hand so aggressively you are going to get in trouble a lot. Think about it -- If you have AJ and the flop comes KJ4, are you going to be hammering that hard with your second pair hand?
