Hand 2: Don't call raises w/ KJo OOP. You told us his preflop stats, but what's he done postflop? Does he min-bet as a probe when he is concerned about his kicker or is this a check-raise? Then he leads after 3-betting the flop. I think you should just call here. There is little chance he's drawing so if he's behind he's probably not catching up, but if he's ahead you just inflated the pot. If a blank falls on the river and he leads half pot you are calling a much larger amount just to see if TPGK is good. Pot control my friend.
