I took some abuse for this one. It's not great, but I don't know if it's as terrible as it was made out to be. Maybe you can confirm how bad it was.
Playing 50p/£1 live game with a couple of regs. We're six handed and effective stacks are £500~ versus button, £270~ versus cutoff. Both villains are quite aggro, but villain on the button is clearly comfortable playing in this game whereas I'm under the impression the cutoff is playing with a significant portion of his roll.
I raise

to £4 utg. Cutoff makes it £14, button 4bets to £42. Neither player has to have a hand here. I call the £42 with the intention of getting it in versus the 3bettor in the cutoff if he 5bets. He calls behind. Flop is

. Checked round. The turn is the

giving me a gutshot nut flush draw. I check, cutoff bets £80, button calls pretty quickly. I call (didn't feel like I had a lot of fold equity, also didn't like the idea of passing this hand.) River is

and I give it 10 seconds or so before I check. It felt like the button was calling to take it away on the river, but wasn't sure how he would respond to my overcall. In hindsight, I definitely prefer betting, but how much? What do we think ranges are here?
Sorry if this makes no sense, I'm literally falling asleep as i write this.
