hand 1: that's fine. i would have bet a little more on the turn to extract value from flush draws and T's.

hand 2: also fine. i would have considered a c/r all-in on the turn, but probably would have wussed out and check-called. he is pricing you in nicely.

hand 3: i would have either bet 350 and planned on folding a raise or i would have pushed directly. when you bet 600, there's no way you can get away from the hand, and you're going to get more action (that you don't want) by potting it rather than pushing.
