Hand 1: yup Standard. He doesn't want you to call his raise.

Hand 2: Nope. Me no Likey. Check-raise on the flop says strength or I'm pricing out my draw (99, 77, T8s??, AA???). Value bet on the turn says strength, Value bet on the river says please raise me with your TPTK or set! The only thing calling your push on the river will beat you, and he's been betting the entire time (except PF) so he's probably not folding... I don't think you get a fold from this push often enough to have it be +EV. Call his bet down here if you think you are winning, fold otherwise...

Hand 3: Good fold. Now, can you fold AK in this same position??
