Who wins in this scenario:

What if: i promote pawn into queen in the wrong square so it will not be captured but my opponent captures it anyways. So it makes my opponent move illegal.

Then i call the arbiter for complaint.

You cant make an illegal move.

Yes you can’t make an illegal move. But this happens in real life. Like what happened in an over the board tournament that I cannot recall. Both players didn’t notice the illegal move. They just found out during analysis. The illegal move was castling. How? The king had moved already.

If they didn't notice until multiple moves after, then you go with the illegal move. There was a GM game where one player castled twice, they discovered afterwards so it was just a part of the game. It's up to the players to notice in time, if they don't the illegal move doesn't get reversed they play on. Depending on the situation, that's generally what happens.

Was it blitz or classical? Was it a FIDE event or run by the local Chess Federation?

@RisingFire i saw this in video. Man vs Woman. The man intentionally make illegal move by promoting his pawn to queen to another square. So it will not be captured. The woman makes her move, capturing the queen by her queen and placing it on the right square. Then the man calls illegal move. The woman argues that his queen was supposed to be on the right square.

If I remember right, by USCF rules you have 10 moves to catch a mistake in play and can correct it. The game resumes at the move where the mistake was corrected. If it is not caught with in 10 moves then the move stands and the game is completed. FIDE rules are more strict. If a mistake is noticed on any move during the continuing of the game. It must be corrected and replayed from that point forward.

Visualize this. White has queen and pawn, Black has pawn about to promote. Black to move. Let's say: 1....d8=Q 2. QxQ this is legal moves and white will win because of extra pawn about to promote queen also. But in the game, black intentionally promote to wrong square, e8=Q so it will not be captured. But white captures it anyways and placing queen to d8. Then black calls arbiter for illegal move. White reasons black makes illegal move first.

I believe someone tried a similar thing against magnus... And they went back fixed the position and moved on.
