Michael Adams's first win at the Tata Steel in round ten was a great achievement especially when his opponent was the ultra-solid Sergey Karjakin:

Endgame Symphony

After Carlsen's quick draw against Karjakin in round eight of Tata Steel many believed that the co-leadership between the Norwegian and Fabiano Caruana will stay before the second free day. The American managed to equalize in the opening and seemed to hold on his own until David Navara started his endgame symphony:

Chinese Perfection

The fourth round of Tata Steel was extremely interesting. Fabiano Caruana came very close to increasing his lead even further but slipped in the rook endgame and only drew to Anish Giri.
Somewhat surprising, but fully deserved the pack of followers was joined by the former women world champion Hou Yifan. She played a true masterpiece:
