(stud8) how best to handle 4th st?

[RustyBrooks]

What is the best move to try to clear the field a little? I'd prefer that the low draws fold. Bet out as first to act, representing that the A hit me or that I have 4 low cards? Or try to check-raise hoping that the K or the late low will bet?

How much do I lose by trying to check-raise and having it check through?
