Hi @eniolw and Congrats @davidlionfish on the solution, this is a real classic!
I making some progress working on my focus and physiology part of my game, in spite of my current low rating. I am looking forward to sharing this progress with the top players in the next tournament (LOL).
Thank you, @rodrook, it's a nice gif! BTW, notice that instead of making a queen, underpromoting to a Knight (yet again) would be mate!
A big problem for me, I often can’t find the best end game moves… But I am working on it :).
