I don't 3 bet OOP with TT vey often (well, like never). I think calling 1.5 from the SB is a better line here HU OOP.

Flop - definitely b/c the flop & see the turn. You are ahead of everything but J/broadway, AA-QQ or a very unlikely small set. What hand do you put him on here?

FWIW, I b/c the miss on the turn & c/r a T on the turn. I might c/c or c/f paint higher than J.
