I just sat down a bit ago, got 4-tables going. 1 orbit max on each. Villain is 'lukieplaya' and is on two of my tables including this one. He seems tight and certainly isn't out of line. He has $101, I cover.

8-handed NL100

UTG short-stacked donk limps, 2 folds, I raise to $5 with Ad Kc. Villain is directly to my left and calls. 3 folds, UTG calls. 3 to the flop.

(Td 3d As)

UTG checks. I bet $11. Villain raises to $31. UTG folds.

Action is on me, what do I do, and what is my plan for the rest of the hand?
