That’s right, I forgot about the CapOne-Orchard merge.
Have you tried applying for an unsecured card at your credit union? You already have a relationship with them, your BK is 8 years old and you have a good credit score (is that a FICO score?). I think you have a good chance.
Check out this thread, apparently this guy was able to get a couple of Amex cards in a similar situation as yours. He was also approved for an unsecured card at Alliant CU. It looks they have a couple of locations in Chicago: http://ficoforums.myfico.com/t5/Credit-Cards/Good-Credit-but-8-yr-old-Bankruptcy/td-p/851746
