The 2016 Zurich Chess Challenge not only features top level chess, but also mathematical excellence: Today, we were glad to welcome a very special and highly decorated guest. Mr Manjul Bhargava, the 2014 winner of the Fields Medal, the highest honor a mathematician can receive and the correspondant of the Noble Prize, has come to visit the tournament. Not only because he loves chess, but also because he's an ardent supporter of Viswanathan Anand and one of his closest friends.

Who will be the successor of last year's king Hikaru Nakamura - tournament leader Viswanathan Anand, who is one point ahead of his rivals before today's last round and the Blitz? Or maybe Hikaru Nakamura himself, who had already demonstrated his tremendous Blitz skills at the opening day? Or the Russian Vladimir Kramnik, who appears to be gathering pace after his brilliant victory against Giri in Round 4?

The focus of today's round clearly laid on the clash of the leaders: Would Nakamura be able to beat Anand with the white pieces and thus take over the lead? But the Indian stood firm and even took over the initiative, so in the end it was the American who had to force a draw. The draw offered a chance for the rest of the field to catch up - and two of them grabbed it brilliantly.

If all drawn chess games were like this, then no-one would be bothered by them anymore. The third round of the Zurich Chess Challenge had, despite without a decisive game, all that chess can make such a dramatic game - sacrifices, time trouble, amazing moves and miraculous saves. Now the stage is set for the clash of the leaders, Anand and Nakamura, in round 4.

The second and final game of the Exhibition match between Alexander Morozevich and Boris Gelfand followed, just like today's games of the main tournament, a dramatic path: First, Morozevich allowed his opponent to win a pawn and gain a probably decisive advantage, then Gelfand returned the favour and the position became drawish only to see Moro blunder again. But this time for good.
