The match has officially been opened. Magnus Carlsen won today to take a 3-2 lead over defending champion Viswanathan Anand in the World Chess Championship in Chennai, marking the first decisive result of the match after four draws to start the match. As I said yesterday, it certainly felt like a win was in the making, as every game had been more interesting and closer to a win than the one before it. The breakthrough finally came as Carlsen switched from 1. Nf3 to 1. c4. Technically, it was an English Opening at that point, but after Carlsen played 2. d4, it transposed into a Semi-Slav position.
In true Carlsen fashion, the young Norwegian pushed through in positions that were technically equal, but in which he had all of the practical chances. He made few - if any - mistakes, and Anand finally cracked in the endgame. Once he had a winning advantage, Carlsen finished the game off without giving Anand a chance to get back in the game. I'll have a complete report on the game up on the site tonight.
The onus is now on Anand to find a way to win a game and get back into the match. And this is the time to do it: Anand will have two consecutive White games in Game 6 and Game 7, as the order of colors will switch at the halfway point in the match. That's a great opportunity to put pressure on Carlsen -- but if Anand lets this opportunity slip, he'll be down to just two games with the white pieces in the final five games of the match, making his task even harder.
White: Magnus Carlsen
Black: Viswanathan Anand
