I loaded that fen into my chess.com analysis page, and it gave me the M2 almost immediately?

FWIW I'm pretty sure I would have missed that M2 in an actual game.
Human chess is partly about tactics and strategy, but mostly about memory

I spoke too soon: when the chess.com analysis engine is set to Komodo 3.3, it gets the M2 in a heartbeat. When it's set to Stockfish 16 Lite, it doesn't get it.

Once the solution is seen, it looks obvious. I wish now I'd started with a FEN viewer that doesn't automatically analyse - I somewhat spoiled it for myself.
