A shoe is what they hold the cards in. I'm not a gambler, either, though I did get quite a lot of information by reading the fabulous book "Bringing Down the House: The Inside Story of Six MIT Students Who Took Vegas for Millions." If you haven't read it, DO SO! It's nonfiction that reads like a novel -- a great novel.
I hated this book at the start of the week. It sounded like pulp fiction, clichéd, trite, you name it. But here I am at the last day thinking, "Darn. Another one to put on my library list!" I may yet be disappointed -- I've had that happen a few times with book club titles -- but Suzanne and crew's track record is really good!
