Loose steal attempt gets 3-bet

[lstephen666]

Fairly early in session. I have a couple of players down as probably LPPs, but they have folded already preflop. The rest of the table has been tight so far, so I decided to go for a steal here.

Pre-flop: (10 players) Hero is MP3 with A[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/spade.gif[/img]
5 folds, <font color="#cc0000">Hero raises</font>, CO folds, Button calls, <font color="#cc0000">SB 3-bets</font>, BB folds, Hero calls, Button calls.

Flop: A[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/club.gif[/img] 9[img]/images/graemlins/diamond.gif[/img] (10SB, 3 players)
<font color="#cc0000">SB bets</font>, <font color="#cc0000">Hero raises</font>, Button folds, SB calls.

Not sure about this raise. I took the opportunity to get the button out. If I'm 3-bet I call and probably c/f the turn UI.

Turn: 3[img]/images/graemlins/spade.gif[/img] (7BB, 2 players)
SB checks, Hero checks.

Check behind here good?

River: 4[img]/images/graemlins/spade.gif[/img] (7BB, 2 players)

What's a good plan for the river? Bet if checked to, or call one bet?

Comments welcome on all of this hand, as I'm not 100% sure of most decisions in this hand.
