Answers.Body: <p>Yes it exists, and there are even many problems created where one side aims at forcing the other one to mate - they are called selfmates problems.</p>
  <p>A simple example:
  White: Kh6,Ph5,Qa7
  Black: Kh8,Qg8</p>
  <p>1.Qg7?? forces Black to mate with 1...Qxg7#</p>

Body: <p>I was wondering if there was a move so bad in chess that if you played it the only move your opponent could do was checkmate you back, through blocking your piece or through moving the king. It would definitely require a discovered check of some sorts but I can't think of any position that would work.</p>

  This reminds me of a game that GothamChess once had in one of his videos:
  [fen "3r4/6Q1/5p1p/4p2p/3PBP2/P3P1Pk/1q5P/2R3K1 w - - 0 1"]
  
  1. Bg2+ Qxg2# {only move} (1. Bf5# {White had mate in 1}) 0-1
  
  White to move could have gone Bf5#.
  But instead, they went Bg2+, which not only was not mate, but also left black with the only move ..Qxg2#.
