Vishy Anand Worst Blunder

World Chess Championship Match, Game 9 November 21 2013 GM Viswanathan Anand vs GM Magnus Carlsen. Vishy Anand makes what I believe is the worst blunder of his professional chess career. It did not take him no more than 28 seconds to make the move. At 0:54 of this video he realizes what just has happened and he knows that the game is over. There is no doubt that Vishy Anand is one of the best World Champions in history. Background Music by Stellardrone: Red Giant Viswanathan Anand vs Veseli
