Magnus Carlsen is the world's best chess player. Still, you think it would take him longer than 79 seconds to beat the world's second richest man.

The 23-year-0ld Carlsen—described as the (pre-arrest) "Justin Bieber of chess"—became a chess grandmaster when he was just 13-years-old, which is probably why Gates said the challenge had "a predetermined outcome."

"Wow, that was fast," Gates said after Carlsen beat him in just nine moves, adding that the only time he feels intellectually inadequate is "when I play chess with him (Carlsen)."
