I'm almost completely new to Stud 8 or better, so I really have no idea if I played this hand horribly or not. I thought the player with the 3 spades showing was still drawing after he just called on 5th street, so I check-raised on 6th to make him call a double bet. Was this a bad play? How might I have played this hand?

Sorry I didn't convert this, but the page to the converter I use seems to be down.
