Getting CR on river for value betting

[jumbojacks]

BB is an aggro postflop w/ 33.3/18.1 over 204 hands.
3.75/3/3.17 postflop AF
My notes:
bet 6 midpair in front of 2 and pf raiser; raises on flop and bets turn w/ QJo overs on drawless board; raises T low midpair over in mid-position on flop and bets turn
Summary: crazy aggressive w/ midpair on flop

Preflop: Hero is UTG with A[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/spade.gif[/img].

Flop: (4.50 SB) T[img]/images/graemlins/spade.gif[/img], 7[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>

His raise just means he has at least a pair. As low as bottom pair is good enough for him too.

Turn: (4.25 BB) K[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets</font>, <font color="#CC3333">Hero raises</font>, BB calls.

River: (8.25 BB) Q[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
BB checks, <font color="#CC3333">Hero bets</font>, <font color="#CC3333">BB raises</font>, Hero calls.

I value-bet here but once he raised I think he hit two-pair. Against a player like him I'm not sure if a call is good at least ~8% of the time.

Final Pot: 12.25 BB
