1/2 of Rxd5: remove Pd5.
1/2 of Rxf5: remove Pf5.

That wouldn't make it black's turn, and so technically it couldn't even be check yet. To make this valid, it will have to be the second half of an already played first half-move.

When joke problems collide!

Tolosa (year?)

White mates in half a move

Lift wK in the air, discovering check and mate. Do not set the King down, or Black can move out of check.

Well, your intent is to remove Pd5 as the last half of en passant. I like my solution better - in yours, you can't prove Black played ...d7-d5 on the previous turn.

I found it, I found it!!!

The whole move is to turn the board on whole turn, 360 degrees.
Tha half move is to turn it half a turn, 180 degrees and then the black king is already in mate.

Didn't I, didn't I???

the answer was to remove d5. It is the only legal half move leading to checkmate.

Mate in half a move.

Same idea. Less pieces. And ep rights are provable.
