4-8 Live: 44 flops set against PFR

[Russ M.]

4-8 Live at the Horseshoe in Tunica. 8-handed preflop, I have 44 UTG+1 and my table image is likely to be tight-aggressive (definitely in relation to other players who play around 75% of their hands). The table consists of a couple of moderately tight players and several loose-passive gamboolers, two of which are in this hand.

UTG limps, I limp, folded to SB who raises. BB folds, UTG calls, I call.

Flop: A-9-4r

SB bets, UTG calls, I call.

Turn: 6

SB bets, UTG calls, I raise, SB 3-bets, UTG folds, I call.

River: 3

SB checks, I...?
