Highlights - Magnus Carlsen Chess Tour Final: Nakamura claims set five 4-3 against Carlsen

After the four rapid games ended in draws, with neither player really coming close to victory, Carlsen took the lead by claiming the first blitz game. Nakamura, needing to win to stay in the set, hit back with black pieces after the World champion got into trouble early in the game. He converted his advantage to make it 3-3 and forced the Armageddon game.

Carlsen, looking to deny Nakamura the psychological advantage of playing black for the second straight game, chose white pieces in the Armageddon game.

Armed with five minutes on the clock to Nakamura's four, Carlsen took up the challenge to play for a win. Since a draw was enough for Nakamura to claim the set, it was important for Carlsen to get a good position out of the opening.
