Nice find. That's hilarious....
Picky engine

What is this?
Maybe you haven't analyzed any games yet so here's what is so funny. White promoted to a Q that Black was forced to take to prevent mate. The engine felt that promoting to a rook was a superior move.

Same thing happened in a leela game. Promoted to a rook and it looked like the engine was trolling.Probably has something to do with the search order. I assume you didn't leave it on very long. Stockfish should evaluate as equal after awhile

Leila weirdness I because the reward settings were flawed in the machine learning and so Leela stretches out won games as long a possible. So yes Leela was trolling.
Hmmm....
