CP: Can a supple hand curry favor with the judges?
SR: Well, if you have some gnarly looking hands [that could be a detriment], but not necessarily. You can try and play the refs a little bit. Say, "It's an honor to be here. I've heard you're a great referee." But they're well-trained. I'm a certified referee myself. [As a referee], you just say "that's a nice-looking hand," but that's as far as it goes.

This guy will beat you in rock-paper-scissors.
