After John Varner showed down a pair of aces on a board that didn't provide for a low hand, Rich Zhu looked long and hard at the board trying to figure out if he might have a way to beat those aces. He peeked again at his cards, tilted his head, looked over the board, thought about it some more. Finally, when the dealer volunteered to help him figure out what he had if he'd flip over his cards, Zhu grinned, shrugged his shoulders, and tossed his cards in the muck.
