white mates in 2

A very nice composition! Here's my view on it.

Pros:

- The key move places a piece en prise to multiple opponent pieces (in this case, 5). Very rarely do these compositions include en passant as a capturing piece, so well done!

Cons:

- There are "only" five pieces that capture the pawn, which is not enough considering the economy (how many pieces are on the board). In the composition below, there are 7 pieces for the same economy (however, note that the composition below doesn't include en passant, so good job)!

- An essential requirement for these problems are the distinct changed mates. For example, in the above composition, for each different capture, there was a different mate. On the other hand, yours only has 3 changed mates for all variations. 

- Lastly, I would recommend implementing the knights. For example, in my composition below:

The two knights already add two distinct tries while barely changing the economy.

 If you managed to add them, you could get 7 focus square pieces, which would be amazing!

I hope you don't take me as too redundant or critical. This is already better than 90% of the chess.com forum puzzles!
