I would not 3bet this preflop...Would you want to see UTG cap this?? Plus a 3bet isnt going to scare anyone away...
On the flop pot odds are 18.5 to 1 and with two outs to your set your odds are 22.5 to 1...but you can expect to win a few more bets if we hit our set on the turn, so I am not sure if its correct but I dont think calling the flop bet is a major error, but I def fold this turn....
