The Knight is pinned by the Rook on b4, so Nxc5 is illegal? Or are there even more additional rules?

Edit: never mind, of course a pinned piece is allowed to capture the piece that is pinning it!

Mate in 0.5

Lift Nf6, discovering check, and watching the g8 and h7 squares still.

Reminds me of another joker:

Mate in half a move

Black

White

Mate in 1/3 move.

The final third of exf8=Q.
The first third is taking the piece, the second is grabbing your new queen, and the final is placing the queen on the board

The first third is taking the piece, the second is grabbing your new queen, and the final is placing the queen on the board

I was thinking f8Q#. The first third is moving the pawn to f8. The second is removing the pawn. I counted grabbing the queen and placing it as the same thing.
