A good documentary, and well, it's the first time I've heard of cheating in chess being done that way, but what's incredible is how they use a toy that moves to choose the correct piece. Then, their friend (the remote control) is the mastermind behind it, because they're indicating all the moves to win. In the end, as it rightly says, the important thing isn't the characters but the story they teach us. I'm not a spectacular player, but I can hold my own at chess, so I'll try to find out a little more about the history of the players.
