Hand 1: I fold pre-flop. But I like the flop CR. I think you get folds here a lot from any hand worse than TPGK. I probably lead the turn for $8, but then it gets tricky if he re-raises.

Hand 2: You can't put him on trips, so after the flop raise the question is whether he has an overpair better than yours (or something you beat, like a T or a flush draw). I might re-raise on the flop, but it's a tough decision. I like the turn and river, a cheap showdown is good here.

Hand 3: I think I bet the turn here, 1/2 pot, but checking behind isn't bad against such a tighty with $30 already in the pot. Definitely check behind on the river.

Hand 4: It's tough to put him on a hand here. TPGK? QQ? Again, with a good-sized pot I don't think you need to value bet the river.

Overall I think you played these hands well.
