You can follow the games here as part of our live platform. Besides the official broadcast, daily commentary is provided on GM Hikaru Nakamura's Twitch channel starting at 8 a.m. Pacific / 17:00 Central Europe.
GM Levon Aronian is trailing Carlsen by a point after losing the armageddon game to GM Alireza Firouzja, who shares third place with Caruana. GM Aryan Tari defeated GM Jan-Krzysztof Duda in the armageddon, so both players got rid of their zero on the scoreboard.

Everyone still remembers the 12 draws in the 2018 world championship match between the two Cs. The last game before that match was a draw as well in the 2018 Sinquefield Cup. After the match, they split the point in 2019 at Grenke, Norway Chess, the Croatia Grand Chess Tour, the FIDE Chess.com Grand Swiss, and the Sinquefield Cup and in early 2020 at the Tata Steel Chess tournament.
The last time a game between the world numbers one and two had ended decisively was at the 2018 Norway Chess tournament when Carlsen beat Caruana with the white pieces after 77 moves.
Back then he started with 1.e4, but this time it was 1.d4, and a 4.Qc2 Nimzo-Indian came on the board. Straight from the opening, the players went for an endgame with rooks and one knight each, where the only difference was three pawn islands for Caruana and two for Carlsen.

Commentator GM Vladimir Kramnik correctly predicted that it was not going to be easy for the American player.
Carlsen: "Frankly speaking, I was thinking during the game that this is probably the best position I've had against him since the first game of the match! So it was very sweet to get that win."
The position after 20.Rhc1.
It seems where Caruana first went wrong was move 20, when he voluntarily allowed an isolated c-pawn. Sacrificing it soon after was good, but he should then have traded the knights and tried his chances in the double rook ending.
"It's huge," said Carlsen. "It's almost unbelievable after yesterday. I was struggling and now... it can change very quickly. But I think after the rest day, Fabiano will be back, and he will continue to play well."

The other two standard games ended in draws and can be found in the game viewer below.
For the armageddon game, Firouzja has a miscommunication with the arbiter. As a result, he arrived late at the board and started with five minutes and 22 seconds (instead of seven) vs. Aronian's 10 minutes but won anyway.

Aronian was totally winning in this game and missed both simple and also some harder (but beautiful!) ways to win and then couldn't hold an equal but unpleasant endgame. It should be noted that on move 40, both players had only 16 seconds left when their one-second increment started. This whole game was more about nerves than anything.

"I just decided to go all-in today, to just play something fun," said Tari about the mini-match he won against Duda. The fun part started with playing the Grand Prix in the classical game and ended with a win in the armageddon.
The young Norwegian seemed in control for most of the game but as the computer showed, Duda had a winning position before he lost the thread:
