World Chess Championship Game 4 - Carlsen exerts pressure, but Anand holds out for draw

Magnus Carlsen (L) and Viswanathan Anand (R)

In a thrilling encounter that lasted longer than six hours, Viswanathan Anand managed to overcome a determined assault from Magnus Carlsen to ensure a fourth consecutive draw at the World Chess Championship 2013 in Chennai.

Anand began with the 1e4 move and Carlsen responded with the Berlin defence that has been popularized by Vladimir Kramnik. After a quick exchange of queens, Carlsen went on an aggressive spree to put the Indian in trouble. The defending champion was forced to call on his considerable experience and defensive skill to bring things back on an even keel.

The game seemed destined for a draw once Anand had defused the immediate threat, but Carlsen refused to give up, forcing his opponent to wage battle right till the bitter end. The Norwegian even managed to put Anand under time pressure, but the Indian knocked off that threat too with a series of quick, accurate moves.

Eventually, after 64 pulsating moves, the two agreed to a draw, leaving the series at a 2-2 stalemate.
