There’s something that made me think lately: Theoretically, there could be a position where the move that normally leads to the quickest mate possible would actually be a blunder.
To show this I created a game with the following position:

Usually 51.Rb7+ would be the right move, of course, but here it leads to a draw (in a won position for white) because then the position would repeat thrice. I know this is all very theoretical since no one would ever repeat this move thrice not realizing that they can checkmate immediately after, but I just find it funny that technically 51.Rb7+ is a blunder in this game’s position. And even the Lichess computer-analysis engine doesn’t realize that, showing full advantage for white after this move which leads to a draw.
