He can take the pawn en passant.

Is this checkmate?
Sort:
en passant
En passant!
Thanks guys. I have a real blind spot for that.
Yep, after 23...axb3 24. axb3+ Na4 and 25. Rxa4#, 25. Nc6#, 25. Qb4#, and 25. b4#. The most beautiful, in my opinion, is 25. Qc7#
Also, I believe that 24. a4 works as well, as Black cannot defend.
Oh, you mean right there...No, he can take en passant.

I won this game by resignation, apparently, but it looks like I should have won by checkmate - am I missing something?
