River bet sizing with 2nd nut

[kb coolman]

Op is 27/13 after about 40 hands.

This is a question about maximum extraction with 2nd nut. I didn't want to scare anyone off, so I put a 2/3 bet in on a small pot on the flop. When he called the PSB on the turn, I figured he had to have something strong playing OOP....AA, AK, or maybe even a weak flush. What would be the best bet size here to extract maximum value, assuming he doesn't have the nuts?

Depending on your read....

You can shove, bet half the pot, or even check to reraise. Really anything here.. no laydown though.

villain's taken such a passive line that i don't think he's betting or getting it all in on the river. i'd prob put in a value bet somewhere around 1/2 pot.

That's what I was thinking, too. I got greedy and shoved. He thought about it for a while, then folded. At that point, I knew he would have called the value bet, so I know I didn't get maximum value for this hand.

I shove this. If you pot the flop shoving the river is even easier since you don't have to overbet.
