James has a really interesting first-hand account of the chess match between Blaine-in-a-box and a homeless man.
The game lasts in the order of six or seven hours. Watching intently, it is possibly to identify a weak, or seemingly inexplicable move. Blaine gives away a bishop very cheaply, relatively early on. Blaine and Greeff, though, are not Grand Masters, and to come along with a full stomach, nitpick the game and depart ten minutes later would be to miss the point. These are two players playing in exceptional circumstances. David Blaine, a third of the way through a feat of endurance, has not eaten for fifteen days. Francois is a homeless guy with a hidden disability.
