Ok, I meant with king by itself. Two kings stare at each other for all of eternity and it's a draw. HOWEVER, the way you obtain the "killer king" award is by the king moving out of the way for a discovered checkmate OR a castling checkmate (which are both very rare).
There's another achievement for castle checkmate.
