Button steal checkup

[private joker]

Live mid-limit game. You're on the button, and the SB is a tight aggressive pro. He respects your play -- including your ability to lay down and your ability to read hands.

Folded to you, and you raise Q[img]/images/graemlins/diamond.gif[/img]T[img]/images/graemlins/diamond.gif[/img]. SB thinks for a moment and calls. BB folds.

Flop comes A[img]/images/graemlins/club.gif[/img]T[img]/images/graemlins/spade.gif[/img]4[img]/images/graemlins/diamond.gif[/img]. SB checks, you bet, and SB check-raises.

What's your line now? What are the benefits of 3-betting here? If you do 3-bet, do you take a free turn card? Do you bet the turn and take a free showdown? What if your 3-bet gets 4-bet? If you just call, are you raising a diamond turn on a semibluff? If you don't improve, are you calling the turn and folding the river? Calling down? How bad is folding the flop?
