That's basically what people were saying about 1.g4, and the reason this game is taking place.

I'm not saying they can be calculated all the way to mate, but that they can be calculated to +7/-7 or better/worse. I tried this with 1.g4 right after I started playing CC and couldn't quite get there. IIRC the best I could get after about a week of analysis was -3.xx or so. This was on 5M-6M nps machine with 16 GB of TT and 6-man EGTBes. I plan on trying this again when I build my new system and, before I increase my ICCF game load significantly. I think this is just a matter of how powerful a machine you use. If I had a dual EPYC 7742 machine with 2 or more TB or RAM, 7-man EGTBs and a week of spare time (2 at the most) I think 1.g4 would be history!
According to this, no matter what white played, it can't stop some -3.xx eval. So you can't say the game was over before it started, unless you claim you couldn't defend 1.g4 yourself.
I did not see a proof that 1.g4 is -3.xx
It may be interesting if somebody post a tree together with analysis that prove it meaning something like
1)stockfish's analysis shows -3.xx against white or worse at all leaves of the tree.
2)If white choose something that is not in the moves of the tree then stockfish's analysis show at least 3.xx for black.

According to Stockfish-dev, both players have recently been playing best moves. But the eval is now -4.12, and is slowly falling with each move.Ovyron wrote: A thing Harvey and me have in common is our dislike for people that drag lost games on and on and on ...]

I hope you're saving those PVs or this game is going back to private
