In the 2023 Tata Steel, Magnus lost 2 classical chess games in a row, namely to Anish Giri and Nodirbek Abdusattorov. It's said that the last time this happened was in 2015. But that's for different players.
If you allow chess960 and focus only on the same player:
In the 2019 WFRCC, Wesley So beat Carlsen 3x in a row in classical world championship games.
Question: Besides that, when was the last time this happened: Magnus lost 2 classical (chess or chess960) games in a row to the same player (focusing only on their games only of course)?
Case 1: Draws counting eg Win-Loss-Draw-Loss-Win means only 1x
Case 2: Draws not counting eg Win-Loss-Draw-Loss-Win means 2x
Note: In either case, I don't mind if it's all chess games, all chess960 games or a mix of chess and chess960 games eg for Case 1 Win any-Loss chess960-Draw any-Loss chess-Win any is ok.
