There's perhaps no more pure test of poker skill than heads-up play. Wide ranges and a single opponent make for the deepest, most decision-intensive form of the game.
So, it's no surprise nearly every player at the top level expects to prevail when playing heads up. That makes it all the more humbling and, at times, frustrating when it doesn't happen. Doubly so when it happens time after time, on the biggest stages possible.
That's the situation in which Daniel Negreanu finds himself after fellow legend of the game Phil Hellmuth handed him another defeat in their series of matches on "High Stakes Duel" on PokerGO.
