Shortest-proof-game challenge


I haven't seen a proof game for this 12-day old position by EvinSung.
I've tried some but haven't solved it. I think it's time for EvinSung to show a proof game.

I posted this position 17 days ago.
Leither has worked on it and received some hints. If Leither is no longer trying it, I'll post a proof game.

I'll wait to spend more time on it until you try the one I linked at #6223.
