opponent did blunder in the last
and see what a smooth checkmate
Very nice but quite common!
I don't think it is common. A king in the center of the board with a pawn in front and a N blocking the two other squares to ensure mate with the Rook...
Not sure if I ever saw this before, not to mention that this is not even an endgame.
Perhaps it is not the most difficult as it is mate in 1 but certainly quite a unusual one!
Seemed pretty common to me (the real problem being that Black fell into it all rather drastically).
This type of mate always Keswick me remember famous Queen sac by an electrical engineer against Max Euwe!
