Hanging around a heads up table may leave you feeling a bit like a pool hustler in an empty bar waiting for your next victim (not that there's anything WRONG with that.) Unlike a multitable event, which begins at a predetermined time, a heads up event is a two player sit and go, which means you are stuck sitting and waiting for another player before you can go. Rather then surfing the Internet or watching your stories, consider jumping into a cash game to maximize your profitability.
It is one of the greatest benefits of playing poker online -- the ring game. Unlike a tournament, where you are locked in for the duration, you can bail in a ring game at any time you decide you are losing too much money, your pot roast is done, or the wife and kids get home and you've got to pretend like you've been working all day. It also allows you to continue playing poker while you wait for someone to take the bait and sit down in your heads up game. Just be sure to keep the heads up table window in view: if the action at your ring game gets hot you may forget and find yourself short stacked before you even get started.
