I think I like a smallish blocking bet. If villian is fairly week he may just check behind, but may be willing to call a small bet. With his remaining stack being at $37.10 I think somewhere around $20 feels right (to this ring game newbie anyway).

check indending to fold to most bets.

So you don't think our 2 pair is good here?

[Fnord]

If he bets something stupid, call.

Without a read it's hard to tell how light he's calling a big river bet.

If he's a known fish, 35-40ish for value is spiffy.

villain only has 37 behind, you're only move is to shove here. He'll have two pair often enough to make it profitable.

I would have bet $4 more on turn, but if I check it is to check/fold.

Shove > check/fold > check/call

[Deanglow]

I think shoving is our only move here. He still calls with a lot worse.

Misread the effective stack size. Easy shove then.

Recently, my opponents sucked out on river like crazy in my games.
Obviously, he called my shove with Qs9s.

Villain just has $35 left for whoever reads this and is like wtf.

I would bet more on the turn, villain looks like a donk, might as well get your moneys worth.

No need, we've set up a river shove nicely with the $20 bet.
