a raise on this board is done a lot with lone Ac. depending on the players i probably peel a turn and bet/check riase paired boards if checked to assuming UTG +2 folds
UTG c-bet into 3 players on a monotone board. And MP re-raised with 2 players left to act.
It's clear that one of them has at least the bare Ace of clubs. And when they do have the Ace of clubs, they're much more likely to have the nut flush than the bare Ace (tight ranges found in UTG and MP obviously prefer suited aces).
So it's a clear fold. Yea, you are getting bluffed some % of the time, but they have it often enough. And if they're competent, they'll deny you all of your equity even when they're bluffing.
People who are saying call are being way too optimistic. Your really expect both players to be stone bluffing with no nut blocker in their hand? That's literally the only thing we're hoping for. And yes, I realize that maybe 5-10% of the time both might have nothing. But the other 90-95% of the time you're crushed or they have the nut blocker which will allow them to bluff you out of the pot on later streets, making this a trivial fold.
I'm assuming you're playing at Ignition or ACR. Yes, the players are not great but you should drop down to .25/.50 or .50/1.00. Trust me, the downswings and mistakes will hurt less.
