If the top two matches finished in Armageddon wins by the players with the lower scores instead of the higher scores (as happened), it would have really tightened things up. Even so, it's still a four-horse race with three rounds to go, with Alireza Firouzja in first with 14.5 points, a point ahead of Magnus Carlsen, two and a half points ahead of Levon Aronian and three and a half ahead of Fabiano Caruana.
Firouzja enjoyed an initiative against Aronian in the classical game, but the latter defended extremely well. Firouzja reached a pawn-up rook ending, but never came close to achieving anything. Aronian's defense was so good that it's worth studying and emulating. Their Armageddon was a tragedy or a farce, depending on one's view of the one-second increment. Aronian was fine almost from start to finish, but a pawn up and safe in the final position couldn't physically move fast enough to get the draw his played (more than) merited, and he lost on time.
Caruana had some terrific preparation against Carlsen, and obtained a significant advantage and a very large advantage on the clock as well. But at some point he couldn't find the precise moves he needed to maintain that plus, and Carlsen's fine defense led to a draw. The opening of Armageddon game didn't go as well for Caruana. Carlsen had a winning advantage soon after the opening, and while Caruana fought his way back to equality he was never close to winning. Caruana eventually lost on time (I think), but he had the nominally worse side of an almost hopelessly drawn position. There was no way he was going to win it, so it didn't matter if it was a loss or a draw.
Finally, Jan-Krzysztof Duda won a very short and lively game against Aryan Tari, and is slowly crawling away from the cellar and towards the leading group. It's too late for him to win the event, but not too late to catch one of the top 4 and to score a major upset along the way.
