Here is one showing the down side of 72o. I heard about this way back and can't remember who thought of it. Leading with one card to come against a single opponent and no chance to win outright. It's not like you would be betting this hand, but it has always interested me that you can be heads up and have every card remaining in the deck hurt you.
