A nightmare tournament for the World Champion Magnus Carlsen continued as he lost his 4th round game to arch-rival Viswananthan Anand. Anand, playing with the White pieces, swiftly outplayed the World Numero Uno in a Ruy lopez middlegame. The exchange-up ending was more than easy for someone of Anand’s calibre, and as such, Carlsen resigned on move 47.
There were a couple more decisive games, both won by White. Grischuk punished Hammer’s over-ambitious opening play and duly won the game while Topalov convincingly overcame Levon Aronian. The remaining games – Caruana vs MVL & Giri vs Nakamura – resulted in draws.
After 4 rounds, Topalov leads the pack with 3.5/4, closely followed by Nakamura on 3/4. Meanwhile Carlsen has only managed a draw from the four games played so far.
