Forced Checkmate vs Time Out

@CalbernandHowbe Ok, so the rule explicitly mentions the word opponent. That clears things, so it will be a draw. Btw, what I meant when I said “it may seem strange” is that it may seem strange to grant white (not black) the win after white ran out of time. Anyway, thanks for the clarification!

"The second rule regards the arbiter's possibility of ending a game as drawn due to a player's lack of effort in winning the game by "normal means". Occasionally it happens in a sudden death time control without increments that a player has trouble in physically executing an indefinite series of moves in the time remaining. The opponent could try playing on this, and continue to play on in the hopes of winning by time forfeit, rather than by winning the position on the board. To prevent this FIDE allows tournament organizers to apply the guidelines in articles III.4 or III.5.[4] A tournament played with article III.4 allows a player with less than two minutes remaining to summon the arbiter and request that a five-second increment be introduced. Invoking III.4 constitutes a draw offer which the opponent may accept. Otherwise, if the arbiter agrees to introduce the increment, the opponent is awarded two minutes in addition to the increment. In a tournament played with article III.5 a player with less than two minutes may summon an arbiter and request that the game be declared drawn "on the basis that his opponent cannot win by normal means, and/or that his opponent has been making no effort to win by normal means". The arbiter may accept the claim (which ends the game immediately as a draw), reject the claim (after which the game continues, with the opponent receiving two additional minutes), or postpone the decision. In this case the opponent may be given two minutes extra, and the game continues until the arbiter makes a call or the claimant's flag falls after which the arbiter makes a decision." - Wikipedia (https://en.wikipedia.org/wiki/Time_trouble)

I guess this answers your question @Spinglass but be in the know though in Lichess (and basically every other chess server) if you have a mate in 1 and your clock runs out the game ends with your opponent taking the victory.

Here's a demonstration how it works on lichess, I modified your position a bit so I got some extra moves to start the clock:

White's only move is Ra1# but as time runs out, Black wins.

This is a constant source of error. Some want even a forced mate in 15 moves „auto-executed“.

Simply no, you have to move it yourself. Otherwise you lose in most cases or draw when there is no way to win (see #1).

So what all the fuzz about?

Sometimes with timeout it is draw it is weird though

It is a draw per FIDE Laws of Chess, but lichess records it as a win for black because of difficulty to code it.

@SPARIMI If for example you're playing a game and your opponent is left with only his king while you still have a pawn or more pieces... If you get flagged (If your time runs out) It'll be a draw since your opponent had no way of checkmating you...
There is nothing weird in the draw timeout.
