Overcall this river?

[mongidig]

20-40 live 9 handed.

HJ: Plays every hand, pretty straightforward and a calling station postflop. He will make ridiculous call downs in situations where he is certainly beat. He will peel with nothing on the flop.

BB: Has TAG qualities, but tonight seems to be playing looser than normal. He sometimes plays passively(Against the better players) and sometimes very aggressive(against the bad players). He has threebet once preflop with AdTd but that was against a loose raiser. He reads hands very well and definately knows the game. He has much respect for me. He doesn't bluff often but I am sure I have seen him do it in the past.

I have TAG image and have not been out of line tonight.

HJ open limps, I raise in cutoff with TdTh, folded to BB who calls, HJ calls.

The flop: Js7s6c

I bet, BB calls, HJ calls

The turn: Js7s6cQc

I bet, BB calls, HJ calls

The river: Js7s6cQc7d

BB bets, HJ calls, and I?
