Man if this is live poker my NORMAL open would be MUCH bigger than $10. And we are talking about 5 limpers in front of you? The absolute stone MINIMUM I'd be making it here would be like $25 pre.
The whole hand is kinda messed because of it. We go 5 ways to a flop where we are effectively against limpers' ranges because we didn't raise enough to really let anyone fold anything. (How we got that ONE fold is even beyond me.)
But whatever, we got here, and we have to live with it. The pot is something like $55 (but let's just call it $50 post-rake). Villain leads for $15, folds to us, and we have a mega draw. Flush draw, gutter, two overs. AND the guy is leading with a sizing that screams of weakness on this 5way board. People REALLY tend to bet bigger live with these wet textures when they have something actually good. This feels something like a "set my price" or "I have second pair and a backdoor gutter and have no idea what to do" type bet.
You're not going to find a much bigger slam dunk raise spot with a semi bluff in live poker than this imo. But whatever. We call.
I mean now on the turn when he bets again I'm probably just calling because I'm confused about what's going on and am feeling less confident about getting him to fold frankly. It's probably slightly better to realize our
equity when we face this size, though I'd still contend we have SOME fold equity here.
So we call, the river comes gin for us, and makes us feel like a genius for not raising the flop. We get it in because we made our hand, and villain can have approximately a billion worse
hands, and really SHOULDN'T have better (note the giant SHOULDN'T not CAN'T here).
When he shows up with this hand we note that he's horrible, but also remind ourselves that we protect ourselves from this nonsense by raising to something halfway reasonable preflop.
