I think something broke for him while playing Caruana in 2018. The classical games were a snooze fest of defensive plays after defensive plays and everything was settled in the rapid tie break in a fairly unsatisfying manner.
He is not the first to complain about that by the way. Fischer hated the format too.
The freestyle championship was better in pretty much every way.
A lot of it felt like watching engines by proxy. One prepared well on a very complex opening. The other found the best meta counterplay and held until he reached the tie break.
Game 12 is a travesty. It was clear he just wanted to move to rapid.
2. 7. Nd5 line is not boring, it's one of the sharpest things to play against Svehsnikov, with pawns marching on both sides of the board. Mainline Sveshnikov on the other hand can be very drawish, with maneuvering play, where no side has a pawn break in sight.
3. It was the beginning of the Leela era, with many new opening concepts. It was a short-lived golden age, with players excited to try new ideas. After this match Magnus had a second peak, incorporating new knowledge, and won quite a lot of sharp games in Sveshnikov.
4. Well, game 12 was interesting, but EV of extra time to relax and prepare for rapid games with Caruana in 2018 was quite high. Fabi wasn't a very good rapid/blitz player back then.
5. Carlsen-Nepo WCC was a massacre, while the games were quite boring, except a few at the beginning. That match or any of the next matches would be a much better example for a case against classical chess.
I myself quite like chess960, and it's clearly the right direction. Opening prep is absurd now, especially at super GM level.
Without prep Magnus would be vastly less likely to win, and he’s not doing the prep because he’s not competing. How exactly is that different than someone not devoting themselves to the sport 20 years ago?
You're making some pretty bold assumptions about competitive athlete psychology here.
I was pissed I didn’t go to nationals in high school largely because I got no sleep the night before due to a crappy hotel stay. Losing a close game to board 1 while trying to stay awake sucked, but I was hardly the only person off my game, so that’s just how things workout.
