A mistake by Carlsen that costs him the game. He should have played 44.Kh3 to put up more stubborn resistance.

And Black won the game on move 60.

Fabiano Caruana joined Anish Giri in 2nd place in the Tata Steel Masters after getting revenge for losing to 16-year-old Gukesh at the Chennai Olympiad. Wesley So picked up his first win of 2023 after Vincent Keymer again crumbled in the endgame, while Magnus Carlsen stopped the bleeding with a draw against Jorden van Foreest.

Caruana pointed “for sure a big mistake”.

Fabi said he was “almost winning, because [Gukesh's] pieces are completely uncoordinated”. How would Gukesh defend against White taking twice on f6? He didn’t!

Fabi followed up with the natural 17.h4! and a very quick win looked on the cards, but he didn’t find the cleanest win and ultimately was somewhat puzzled when his opponent resigned on move 36.

In the most eventful round of the 2023 Tata Steel Masters so far, Nodirbek Abdusattorov extended his lead to a full point after obtaining a remarkable win over Arjun Erigaisi. Sharing second place are now four players, as Wesley So and Praggnanandhaa Rameshbabu both scored full points to join Anish Giri and Fabiano Caruana in the chasing pack. In the Challengers, Alexander Donchenko is in clear first place after beating former co-leader Mustafa Yilmaz with the white pieces.
