  Checkmate overrides the 50 move rule.
  
  [Fide Handbook Article 9.3](https://www.fide.com/fide/handbook.html?id=171&view=article):
  
  > The game is drawn, upon a correct claim by a player having the move, if:
  >

  The player making the move that mates could claim a, but he of course won't do it because he is about to win. The player losing *does not have the move* after the checkmate, so he cannot claim the draw.
  
  This interpretation is also confirmed by Geurt Gijssen, in his column [An Arbiter's Notebook from 2006](http://arbitri.lombardiascacchi.com/Chesscafe/2006_05.pdf):
  
  > Regarding your remark about the 50-move rule: only the player on move is

  You are allowed to make 50 moves to achieve mate.
  
  If you make 51 moves, your opponent can claim a draw.
  
  You do not make a move to create the move violation, if you have not mated or otherwise ended the game before 50 moves have been made, the player on move may claim a draw.

  The FIDE later [updated](https://www.fide.com/fide/handbook.html?id=208&view=article) the laws, after which a duplicate question was inadvertently [asked](https://chess.stackexchange.com/q/19710/315) (by me) on this site. The answers to the duplicate are interesting, considerate and *contradictory.*
  
  This suggests that, unfortunately, there may exist no common understanding as to what the rule in question actually means.
  
  The irony is that players with opposite interpretations of the rule can perhaps agree that the answer you are now reading were wrong, insofar as each opposite player believes the rule in question to be unambiguous, but unambiguous in opposite ways!
