Game 4 at Chennai World Chess Championship Viswanathan Anand vs Magnus Carlsen 1/2-1/2: Were it not for reigning World Chess Champion Viswanathan Anand's 'Houdini' escape act with clever defence, challenger Magnus Carlsen could have scored the first win of the event.
The World Chess Champion survived the Berlin Defence with an extremely patiently played Game 4 in Chennai. Carlsen tried to push with all his might for a win while playing almost the entire game a pawn up, but it was not to be. Carlsen did not play the Caro Kann as he had done with Black in Game 2.

The Berlin defense became famous after Vladimir Kramnik used it to beat Garry Kasparov in the World Chess Championship Match of 2000 in London. Carlsen deviated from the more popular line of 10...Ke8 with 10...Be7. It's not a novelty, but it has particularly been played lately by Jon Ludvig Hammer - Magnus Carlsen's friend and second. Also, on the 15th move, Carlsen went Be6 instead of the more popular Bc6.
The 64 moves of Game 4 were pure gold. Anand had won a game versus Sergey Karjakin earlier this year by using the 4.d3 sideline. However, he used the main line against Carlsen in Game 4.
Magnus Carlsen went into a long think at the 18th move to decide whether to take the a-pawn or not. Thereafter, the game became a struggle of regrouping pieces while Black had to find a way to activate his Black Rook on a8 despite being a pawn up. White managed to withstand any damage by advancing his Kingside pawn majority and keeping the pressure on Carlsen.
The position became extremely complicated. Anand found a fantastic resource in 35.Ne4! which helped him to finally open up Black's King on the Queenside and equalise. The defending champion remained a pawn down, but as more and more material got exchanged, White came closer to a draw and finally achieved it.
Right till the end, Carlsen even tried all kinds of checkmating threats living up to his promise of playing to the end, but Anand was up to the challenge all through. The game lasted just about six hours.
Eight classical time-control games are still to be played in the 12-game World Chess Championship Match. The score is now tied at 2-2. The last two games have been deadly energy-draining fights to the bitter end. More exciting chess is surely likely after the second rest day on Thursday. -- Rajat Khanna
