For players craving action and the ultimate test of their skills, heads-up poker has always been the game of choice. Whether it was Stu Ungar relentlessly destroying all comers in decades past, or the likes of Brian Townsend and Patrik Antonius doing battle at a $300/$600 table online, these confrontations have always been the stuff of legend.

More importantly, heads-up no-limit hold’em is also the most profitable format for a skilled player, because there is nowhere for your opponent to hide. Not only do you have to play almost every hand, but post-flop competence is a must. To an expert player, this means the opportunity to continually exercise his edge by making better decisions than his opponent and gaining more insight into their game than they can into his.
