Do you fire one more time for value?

[MJL]

$5/10 just sat down. Two key players this hand.Older guy I've seen before seems tight passive (TP)and a young guy just showed down a J6 suited in LP.

I'm big blind. 3 limpers then TP raises. MP calls all including small blind fold to me. I have 8 [img]/images/graemlins/diamond.gif[/img]T [img]/images/graemlins/diamond.gif[/img] I call. The limpers do what I expect and call.

6 to the flop 12BB.
K [img]/images/graemlins/spade.gif[/img]T [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/diamond.gif[/img]

We check to raiser. He bets, LP calls, I call and one limper calls.

I check limper checks TP bets LP calls I raise. The limper and TP folds.

Heads up with LP 13BB

I bet here but questioned if I should. It was very likely LP had a K, but he could have a T with a better kicker or very possibly chased the flush.

Would you have bet for value?
