I disagree with
@NotRealNameNoSir statement that is reasonable to believe that no cards in hand and you shouldn't be eligible for the board high hand pot. The whole game is ridiculous and is a complete about-face to most every other card game played, but, it is a game. I put my money in, so, I have a stake in the hand. The game is designed to have a disappearing board. What if everyone in the hand has less than 5 cards including the board, what's the best high hand? Is it a legitimate hand if there are less than 5 cards in it? The usual explanation is "your best 5 card hand on the board for the high," so is everyones high hand void since there aren't 5 cards? Then the low-in-hand is the only winner? If the board is community, I've entered the pot legally and haven't folded, why shouldn't I have a chance at playing the cards on the board as well as my empty hand? I had a hand when I started, played by the rules of the game, I earned a chance at the board as well.
Granted, it would be extremely rare that this would occur, but, it is possible.
