The most exciting games of the London Chess Classic 2012 would probably be the Round 8 encounter between World Chess Champion Viswanathan Anand and US Chess Champion Hikaru Nakamura. The game diluted to an endgame with a plus for White, but soon enough Nakamura had the tide turn in his favor. However, in the nervous tension, Nakamura handed the chances back to White and had to settle for a draw. Replay the game with Chess King. In the position on the left, Black plays 50. …b2 and hangs in for a draw. Black’s 50. …a3 would have easily secured the win because Black would be threatening to make two not one Queen and would not be worried about a checkmate or Queen promotion by White. However, 50. …b2 changed all that and put the pressure on Black.

Anand, Viswanathan – Nakamura, Hikaru
