Answers.Text: @Universal_learner There are only 3 situations in which the arbiter can intervene 1) 5-fold repetition 2) 75 moves without a pawn move or capture 3) Impossible for either side to checkmate. If there is an increment of even 1 second then neither side is ever going to lose on time. The arbiter better start counting to 75.

Body: <p>I was watching <a href="https://lichess.org/wBoUa9PL" rel="nofollow noreferrer">this game</a> on Lichess.
  Both of the players have the same resource i.e., the king and only a bishop. The bishops on the board are of the opposite color. But the game was continued and one of the players flagged on time.</p>
  <p>I ran a full computer analysis and the engine has shown the position as a draw. But, since the computer allowed the player to continue the game with that resource, my question is whether it is possible to win a game with &quot;ONLY&quot; a bishop, provided your opponent only has the same? If yes, then what should be the checkmate position? and will the result be different if your opponent has the same color bishop?</p>

  I was watching [this game](https://lichess.org/wBoUa9PL) on Lichess.
  Both of the players have the same resource i.e., the king and only a bishop. The bishops on the board are of the opposite color. But the game was continued and one of the players flagged on time.
  
  I ran a full computer analysis and the engine has shown the position as a draw. But, since the computer allowed the player to continue the game with that resource, my question is whether it is possible to win a game with "ONLY" a bishop, provided your opponent only has the same? If yes, then what should be the checkmate position? and will the result be different if your opponent has the same color bishop?

  According to the [FIDE Laws of Chess](https://old.fide.com/fide/handbook.html?id=208&view=article):
  
  > 5.2.2 The game is drawn when a position has arisen in which neither player can checkmate the opponent’s king with any series of legal moves. The game is said to end in a ‘dead position’.
  
  The game position you show is not a draw because there are series of legal moves ending in checkmate for either side.
  
  ```
  [FEN "8/1k1b4/8/2B5/8/K7/8/8 w - - 0 1"]
