How to castle properly in chess960 (otb)

I am pretty sure you guys are highly misunderstanding sargon here. The whole point of the rules of chess is that the rules are separated into chess rules and tournament chess rules. Not sure how it is translated in english, because I studied the rules in german, but there is a solid difference between having made a move and having completed a move. When the rules specify whose turn it is and who made the last move, clocks aren't introduced yet because we are in the chess rules part, not in the tournament chess part. No matter what the clock says, after you let go of the piece you wanted to move (i.e. the king, because castling is considered a king move), the opponent is allowed to move. I agree that this is an inconsistency in the rules. However, I cannot imagine that any arbiter would decide against reconstructing the position and allowing 0-0 to happen.
No, the castling hasn't been made until both the king and the rook have moved (and been released), see the rules I quoted in #14.
Thx, @hairbeRt and @Dr_King_Schultz

You can explain it a hundred times that according to Article 1 one has the move if the other one has moved. It has nothing to do with the completion of the move. Do you understand? No clocks, no touch-move, and so on. Please read #2 (again)!

Which castling? @RapidVariants 1.Kf1-g1 full-stop. A legal move.

Find the rule that says when a move has been made when it's just a regular move. It doesn't exist,all we know is that it happens sometime before you press the clock, so the rule about castling takes precedence.
The problem presented by Sargon is in my opinion valid.
The FIDE rule are:
You release a piece -> made your move (you opponent is allowed to move
You press the clock -> you completed the move

If you watch Otb Blitz games, this will occure quite often when players are in time trouble.
I think to put the king of the board is a good idea to handle this.
@Sarg0n After white moves Kf1 the white player still possesses castling rights so black is not allowed to do anything until white has pressed the clock. White can move Kf1 and think as long as he want because he still possesses castling rights.

In the Nepomniachtchi - Wesley So FRC game with the castling incident. There was actually a loophole that
could in theory have been exploited. Imagine the h2 pawn was removed and Rh8 will be checkmate okey. The arbiter said that Nepo had to move his rook somewhere, so if mate through the h-file was possible that could in theory had happened.

Nepo: Rf1 - Kg1 (Arbiter oblige mandatory move with the rook) Rh8 mate 🤣

Yet another weird rule, yet another one who hasn’t got it either.
To sum things up: the castling rules for FRC is not clear OTB.
