  What is the shortest known on the board game played between GM rated players that ended with a checkmate? "Shortest" does not mean the game has to be very short.
  
  Note: Edited this question twice clarifying some ambiguity.

  Keres-Arlamowski 1950, comes very close
  
  ```
  [FEN ""]
  [Event "Szczawno Zdroj"]
  [Date "1950"]
  [Result "1-0"]
  [White "Paul Keres"]
  [Black "Edward Arlamowski"]
  
  1. e4 c6 2.Nc3 d5 3.Nf3 dxe4 4.Nxe4 Nf6 5.Qe2 Nbd7 6.Nd6# 1-0
  
  ```
  
  I heard Mr Arlamovski was an IM at the time - but given Keres' level, and the fact that there were many fewer IM's back then - probably puts the game into the GM level category.
