Thanks for the interesting post! Out of curiosity, did you check with an engine how much worse your 17 "misses" were than the moves that Magnus actually played? Whenever I do this exercise, I'm always surprised by how few of my guesses are significantly worse than the GM move. Yet apparently those few moves per game are worth like 700 rating points!
I think the only lemon was 21... d5? But the computer evaluation might not be as important as the moves having some kind of coherence that allows you to put pressure on the opponent. After all, Fabi was only significantly for one move out of 66, but he'd been under a ton of pressure for so long it's not surprising that he eventually made a mistake. I assume that some of my moves with black would have allowed Fabi to build up uncomfortable pressure that would have led me to make a critical mistake long before move 66.

Oh and 18... Rf7 isn't great either - the eval goes from 0.0 to 0.6. That's probably where my position gets awkward and Fabi goes to work on me.
