Crushing the Berlin

Round nine of Tata Steel saw Magnus Carlsen firmly occupying the first place after a win against his second Michael Adams. The other big news were Wei Yi's first win in the event. And what a win that was:

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:

Round two of the World Cup continued with many interesting games. The rating favorite did well in most of the games, but there were a couple of exceptions. Sergey Karjakin lost to Alexander Onischuk with the black pieces, and the other surprise was pleasant for the hosts:

Gruenfeld defense.} Nf6 2. c4 c5 3. Nc3 d5 4. cxd5 Nxd5 5. e3 {In search of
innovation! This line is quite fresh and fashionable. White is mainly pinning
his hopes for an opening advantage with one of the following continuations:} (

Nimtzo-Indian/Tarrasch openings, Tomashevsky,E (2714)-Leko,P (2731) Sochi

play neither of these openings, at least with the black pieces. He is an
expert of the Panov attack, but as White.}) 6. bxc3 Qc7 7. Bb2 $1 $146 {[%csl
