This is a tough spot in a super-bloated multiway pot.
I think the preflop raise is a bit too small. I would’ve made it 25-30 here. Accounting for all the limpers and your position.
As played, I think a call on the turn would keep all his bluffs and worst hands in going into the river. Check-raising is very strong and you would not get worst to call. We also checked the flop as the PFR, and then woke up when the King came. Our hand is pretty face up on this dry board.
