Final move of lover from Brno announced (9)

Ross

I believe the answer is:

checkmate

'final move' is the definition.
(chess)

I cannot understand how the rest of the clue works.

(Other definitions for checkmate that I've seen before include "Inescapable attack in chess" , "ending on board" , "defeat on board" , "Declaration of chess victory" , "Chess game ending" .)

I've seen this clue in The Guardian.
