Hand1: Why the weak 3-bet? With those stats + UTG raise he's likely to have something strong enough to call a much stronger 3-bet. I make it $4.50 to go. Post-flop it looks like a battle of the overpairs...doubt a 24/1 is raising 22-88 UTG.

Hand2: More weak betting on every street. 1/4 pot? What's the logic there? I never bet less than 1/2 pot. Should I be? I also don't see the purpose of the river blocking bet. Seems to me you should either bet the river for value, or check to induce a bluff/pot control.

Hand 1: Yeah, weak 30bet pre, then you lead minimum? But yeah, felt here.
Hand 2: Do you really want to c-bet overs 1st to act out of 4 on a drawy board? If you get called you have no clue where you're at.
