Check/fold would be one way, sure. Another would be to come out with a sizeable bet to represent you tripped up on 5s with the hopes that a better hand will fold.
As it played out, sakirpasam made a big mistake just calling the turn - you were afraid of his possible holdings and displayed weakness to him, but instead of attacking that he showed more weakness back at you. I wonder what Hineck had? A weak king perhaps?
