A5o value raise?

[Diplomat]

This is a hand a friend of mine played in a rediculously good 10-20 game. I thought it would fit into this week's theme of value betting.

UTG, 2 MPP's, and an incredibly strong player on the button (ie. me) limp to my friend in the SB who holds A[img]/images/graemlins/spade.gif[/img]5[img]/images/graemlins/heart.gif[/img]. He completes, the big blind checks.

The flop is A [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img]. Checked around.

The turn is the 5 [img]/images/graemlins/diamond.gif[/img]. My friend bets and is called by an aggressive player in middle position.

The river is the 6 [img]/images/graemlins/spade.gif[/img]. My friend bets, the aggressive player raises.

Anyone agree that this is a good spot for a value three-bet?
