Rarest chess move

Game 3347408 features what has to be an extremely rare move, namely Bh1 checkmate.

I wonder how rare this is relative to moves like O-O mate or c8(B) mate

bd5 works ...

Perhaps even an en passant giving mate is rare...

O-O # or O-O-O # would also be rare.

But the rarest chess move is pawn8/B or pawn1/B.

I don't think I'll ever see a move like exd6ep#

Not rare but lovely.

The fork is wonderful. And discovered check!
How often do they both come up?

White responded with 2. hxg6 and yelled 'mate' because he knew the e.p. rule.

This problem has an interesting mating pattern.

White to move and win.

who actually says "mate"?

probably the same people who announce 'Check!" like it's the winning move
