played it together. He'd just sort of come in while
I was asleep and move a piece. I'd wake up the next day,
move another. Which side are you? Black. So your last move was
knight to queen one? Yeah. How did you know that? It's difficult to explain. It's... It's a type of puzzle
called reverse chess. I invented it actually. You're presented with a board
in the middle of a game but, instead of having to
work out what comes next, you use maths,
probability and reason to deduce what came before. It didn't really catch on. Nobody could ever solve them
