Weird 5/10 hand; River decision

[mmcd]

All stacks are ~1300. Full game.

MP open limps. CO, who has been playing very LAG preflop makes it 40 to go, and I call on the button with J [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img], blinds fold.

Flop:

T [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img]

Checked to the LAG who bets 80, I make it 180, limper coldcalls and the LAG calls.

Turn:

T [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] Q [img]/images/graemlins/spade.gif[/img]

Checked around.

River:

T [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] Q [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/diamond.gif[/img]

They both check to me again.

Value bet or push?
