Information is worthless here, because all it does is make your decision harder, and lose you chips. Unless you can very surely fold or 3-bet to a flop raise, which would be dumb, IMHO, there's absolutely no reason to bet.

A check = chips, because Villain is going to be contuination betting all those hands that missed, and you're just going to let him hang himself.

With a bet, your opponent gets chips from better hands, can make you laydown on the turn, and is spewing chips in every sense of the word.
