That's a great video. I think the full analysis of that board showed that the devil fucked up royally and he's hoping the guy doesn't see it. and the angel is looking at the piece that needs to be moved.
I can't take credit for the analysis, I didn't do one myself. I just read some backstory on that painting before.
Basically glancing at the board it looks really really bad for the guy. But the devil messed up so badly he left an opening for him to win the game, even with the board looking as hopeless as it does. The TL;DR version of something I read once.
no problem
