Ok, that's the insufficient material rule. White, despite an overwhelming material advantage, can't win because he ran out of time. But guess what, black can't win either because he only has a K left. Hence, an insufficient material draw. You're probably not buying any of this so I took the liberty of doing a "search forums" for you.

Have noticed this happen several times, but only now was playing on a computer to be able to report. Game should have been a win for me based on time, but game was considered a draw (+0) for insufficient material. Now if you look at the board, the opponent was obviously about to win. That, or what actually happened, they ran out of time. How would insufficient matterial even be an option?
Not sure how to post the game, but it was Dec 9, 2014 vs unseenunseen.
