Anand plays 28.Nf1 here and goes down in a blaze of glory

The tragic 28.Nf1 is possibly going to be the deciding factor in the Viswanathan Anand – Magnus Carlsen Chennai World Chess Championship 2013. Viswanathan Anand went into Game 9 with a determined attack and almost crushed Black with a Kingside pawn onslaught. But for the 28.Nf1 blunder, possibly the game could have even been a draw that is if Carlsen could have survived the scary attack. Fate struck while Anand fans were ready to celebrate a fantastic win. Carlsen wins his third point in the match and just needs 1/2 point from the remaining three games of the 12-match World Chess Championship. Anand will have to win all three just to draw level and force a tiebreak. Read the full report on Chess Blog.
