How much was the buyin for the sng?
Why would this matter?
I think this is a call here, especially without reads on the villain. Most of the time you're looking at TPMK like KJ, K10, etc or a flush draw, maybe nut flush if you're not holding the Ad or worse is TP with a flush draw, giving them a ton of outs if they're called.
A set here is possible as well. The flop is 180 and you over bet by a lot with 275, so you're practically telling everyone at the table to you have a K or better. Knowing you've put that much in, a set might shove here to get max value if they've read you right. And if UTG+1 does have a set, its a good shove to protect against any flush draws.
I don't see 2 pair a lot here from UTG+1. Unless they're a really bad player. Not impossible, but I dont see it a lot. K8, K3, 83 aren't calling a lot of PFRs.
So, without any reads, you're either holding the best hand vs TPMK, or at worse a TP with FD, or just a flush draw so you're still good. Or you're facing a set and drawing to 2 outs or maybe a runner runner flush if you have the Ad. While sets are not impossible, I think you beat far more hands than you lose to, so I would make this call and hope for the best.
