Las Vegas chess tournament hopes to make game cool
Chess is not the kind of game traditionally played for high stakes in Las Vegas, but it is getting an image make-over.
This weekend players from all over the world attended a Vegas tournament promising a $1m (£624,000) prize, the biggest in competitive chess.
It was organised by the first-ever African-American grand master and came complete with stretch limos and big screens for the spectators.
The BBC's Alastair Leithead has been watching the new spin being put on an ancient game.
