The Chinese Wall?

I do not know about you but for me the first association that comes with China is the Great Wall. Build long time ago to protect against the aggressors it remains one of the world's miracles.
One might expect that the players from this country will play solid chess, build a wall in front of the enemy pieces before doing anything else. Nothing is even close to the truth. Take a look at the first game of the formidable match between Wei Yi and Ding Liren, two of the best Chinese players at the World Cup:

Drama

Not all the Grandmaster games are completely logical. Even those at the top level. GMs remain human beings no matter how high their ratings are and this sometimes prevents them from conducting the game to a logical outcome.
As in the following game from round seven of the Tata Steel tournament.

Fighting Chess in Wijk aan Zee

The Tata Steel tournament remains the best start of New Chess Year. A lot of things are happening as usual, with Magnus Carlsen being on a minus score after 3 rounds, and some of the other top guys suffering.
In round four one of the hidden favorites of the event won his third straight win:
