Well UTG doubled up on a BB special by aggressively betting out his two pair, but other than that no reads.

Is there an optimum way to try and take this hand or is it a lost cause?

Edit: Lemme elaborate. So this is probably the 2nd hand I've raised all SnG. I get a limp/call preflop and a check/call on a blank flop. I'm figuring a pair of tens, a PP, or a flush draw at the minimum.

King of spades comes on the turn. Scare card for me, but can it be scarier for him if I fire on the turn as well?
