3-bet pot. No real history on villain. Pretty sick spot on the river imo because I rarely have a boat there. Villain leads out into 2 deep stacked players so he's obviously pretty strong. I put him on hands like AKQxh or similar or JJxx. Feels pretty sick to fold but at the same time I don't know how often he would turn a strong draw into a bluff on this runout. Thoughts?

His line isn't all that unreasonable with missed draws since we're supposed to have a lot of missed draws ourselves. We actually show up with a strong hand here instead so I think this is a call minus good reads against villain.

I'll give the same answer as I did in the duplicate post.

Try and control Pot sizing until forced to give it up. I can fold this on the flop to a pot size raise of my 1/3 pot size lead.
