utg has a flush draw, quite likely.

flush draw or set. A better one pair would've 3bet. That's why the dude bets the turn: he is pretty sure he's ahead of BB often enough but doesn't want to get free-carded by UTG.

An alternate line may be to call flop / donk turn. How does that affect your interpretation of the other players' actions on the turn?
