Yes, I noticed this one too:

https://forum.computerschach.de/cgi-bin ... #pid135137

Cfish 041020 at 22 threads of 12x3GHz Xeon X5670 (SSE4.1) took at two single tries once 1'20" with Use NNUE Pure and once 5'11" with Classical eval.

Not quite sure, if game was already won at this point anyhow, but it's a single best move and maybe a real game changing one yet too.

Before 76...Rg8(?) chances to hold it for Black were much better, There hadn't been any progress since 40th move before that, just shuffling, looked somewhat like a fortress.

77.e5 seems to be not so easy to find for LC0 itself without move history, using somewhat civilized hardware and maybe not the single one very best net, tried just this one:

In the game SF's eval also went up some sooner than LC0's:
