Hero ??

Both villains have half stacks and are limping, so they're pretty much fish. Iso size pre? Now what on the flop? b/f seems bad. b/c seems marginal. Check/shove sounds tenable, but he's pretty much calling everything better, so it would be a value shove?

Hand 2)

Like 4 hands in. The PFR is not bought in full and he's already limped a hand, so it's safe to assume he's a fish, but what kind, I have no idea. The BB left to act is a standard 10nl reg (aka, a nit).

3b'ing seems bad since, on the whole, raises from unknown fish are going to be with hands they don't intend to fold preflop, and I have no idea how much pressure it will take to get him to fold postflop.

As for flatting: since I have no idea how to exploit him with marginal hands and air, I kinda feel I'm just nut peddling a short stacker, which doesn't feel great.

Folding seems weak when it only costs 2bb's to see a flop against a fish with a decent hand. Then again, I lean toward this because I like mid SCs because they give you so many options to have such a wide playbook on so many flops, but when I have no idea what types of plays exploit this player's style, then it's like lol who cares.
