A chess debt

Madonna's hubby, Guy Ritchie owes actor Jason Statham a load of cash. All from playing loads of games of chess.

I played more chess with Guy on that set than I've ever played in my life...He owes me a lot of money because he lost so many times.

From femalefirst.co.uk. As for myself, I think the most of I've ever owed from losing games is a schooner or two.
