Are you referring to the odd individual game? Magnus beat Lazavik pretty badly in the SCC and knocked Sindarov out of the Freestyle final.
The ones that specifically come to mind are Lazavik vs. Carlsen, Speed Chess Championship 2025 Semi-Final, Round 3, and Sindarov vs. Carlsen, Freestyle Chess Grand Slam Finals 2025 in South Africa, Round 1 of the Group Stage Finals.
For instance this is why Carlsen was so crushed by his loss to Niemann in 2022 (that led to the cheating claim controversy). Niemann actively avoided a draw and then systematically outplayed Magnus in a very difficult R+N v R+B ending. This is also why players like Erdogmus seem to have so much potential. It's not the tactics - which is basically a prerequisite to high level play, but his ability to just systematically grind down extremely strong players like MVL.
