If you watched 60 Minutes this week there was a segment on a young man named Magcus Carlsen. Beyond description if you play chess on any level. He played an exhibition where he played 10 masters at once...with his back turned. He could not see the moves they made and played each match out using his minds eye. He beat them all.
At 13 he played what was believed to be the best chess player ever in Gary Kasparov...to a draw.
