Hand 1:
I think folding is bad. I'll probably raise this to kill SB's odds for a gutshot/2pair/overcard draws in addition to gaining value with A-high/overcards/backdoor flush/st draws.

Hand 2:
With loose standards preflop, I'll be 3betting preflop most of the time. Flop is creative, but I think the turn c/f is fine. This might also be a good spot to run a complete bluff, but it's hard to follow up OOP on the river if he calls. The board is pretty moist by the turn, so c/fing might be best.
