Wow. I worked my way through it but it still doesn't make sense to me.
Bewildering sequence
I think what's even more wild is that the final position here isn't even all that clear. But if you keep following the plan of the engine you realize it's impossible to stop black from stacking rooks on the c-file, winning either the d or g-pawn, and creating unstoppable passed pawns. This line is freakin' bonkers. Nice find
Reviewing a game with the engine, I just discovered a bewildering tacital sequence. Defnitely not something I was going to calculate correctly.
