He cheated.
The "Smartest" Chess Player Ever

I knew before he explained it how he did it because, remember that old comedy "Night Court?" I read a book a long time ago, written by the guy who played the judge. It described a bunch of different scams, and one was where he bet that he could play simultaneously against ten GMs, and win or draw against at least five of them. He explained that all he did was arrange it so they were playing against each other.
Watch as he beat two grandmasters! And please share your thoughts and laugh :)
