What's the rarest kind of checkmate?

is discover checkmate rare cuz i did it just now lol

My thinking is en passant checkmate

A king walk topped with a 'dirty' mate is pretty rare.

OWİE baby😎

This is one of the rarest.

If you like "pinned piece" checkmates, our club had a nice one.

If anyone manages to execute the following checkmate (or something similar) in an actual game, his IQ must be ridiculously high.

When i saw the name of this post i thought of chessman18

chcek mate by peon in the middle of the table..is rarest

The rarest kind of checkmate are the ones that only happen once. A sequence of moves that has only happened once in all of chess history. Can't get any more rare than only happening once.

its about type of check mate...not moves

it's rare because no one plays this way
