World chess champion, Norway's Magnus Carlsen retained his title, defeating Indian challenger Viswanathan Anand in the 11th round of their title match at Russia Sunday.
The reigning world champion called off the exchange sacrifice blunder or bluff of Anand on move 24 and wrapped up the 12 game in 45 moves.
Interestingly, Anand went for the misadventure of exchange/sacrifice - giving up his rook for Carlsen's bishop when he was enjoying a slight positional advantage.
Carlsen scored 6.5 points first to retain the title that he wrested from Anand last year.
