It’s a speed chess game I just watched. Let me know if I screwed this up. I can’t copy and paste from the site.

I was so fixated on how black was going to win - I didn’t see the danger at all. I only knew black was toast due to the evaluation bar suddenly indicating mate in 2.

      I could go back through my games.
