Thin Value Bet?: NL $400

[Big_Jim]

BB is a 2+2er. Seems to play well. 21/7/2.5 after about 1800 hands. Probably not paying too much attention, though, and plays a bit tight, due to multitabling.
MP is about 30/15/2 after about 100 hands. Haven't noticed anything terribly donking from him.

Hero has been playing fairly LAG.

Is this a bet? How much? What worse hands are paying me off here?

If they have been paying much attention, they should know that I hate getting checked to twice.

EDIT: Somehow... the starting hand was not right....
