Strategy games such as chess have long been considered important ways to measure artificial intelligence. But A.I. researchers at Carnegie Mellon University chose a different, and in some ways, more challenging game: poker.

Doug Polk, 26, is considered the best heads up, or one on one, no limit Texas hold 'em player in the world. He's defeated countless opponents and won millions of dollars. Polk bet his reputation that he could beat Claudico, Carnegie Mellon's artificial intelligence super computer.
