That makes no sense at all because on that hardware you use (2000nps for LC0) and that TC SF is at least 500 Elo stronger, so it would take tens of games before you see a first draw, and a win by LC0 is virtually impossible.

Resignation is too early. In the final position, even thought SF is up two pawns, his Bishop is pinned at a4. If SF plays b5 to defend it, the bishop is permanently trapped there. Just my analysis cuz I'm not using an engine.
