Body: <p>What is the shortest FIDE classical game a grandmaster lost? It can be either resigning or checkmate. The opponent doesn't necessarily need to be GM. Forfeits don't count. Only serious games count, instead of resigning after one or two moves as a form of protest like <a href="https://en.chessbase.com/post/gibraltar-flash" rel="noreferrer">this</a></p>
