Figuring Out Card Tricks

I love brain teasers, most of all I love trying to figure out magic tricks, I'm getting pretty good at figuring out card tricks, misdirection I have no problem with, trying to work the cards with my fat fingers and lazy nature, now that's the tricky part. Trying to win bets down at the local, even harder, even when you're right on the money with how someone did the trick they don't don't have to admit it, so you lose most of the time every time.
