The overall arrangement of the pieces in Chess960 seems so weird that I have a question about it: should there be castling at all?

    @RewanDemontay You edited out precisely why I thought the question was OK...the narrowing of his basic premise. I want to edit it back some to include his supporting prose. Jan 29, 2020 at 22:07
  • The headline question is now very different from the one in the body of text. Which should I respond to?

  • The headline question is not “too broad” (although I can understand the temptation to classify it like that, given that once it is hit with that description it is fair game for moderatorial blocking) any more than the question “is the pope catholic?” too broad. Instead, it’s a question where the answer is too obviously “yes” in most cases

Yes, castling is good, especially when you are about to be attacked by say, a knight and queen, a king castling to the other side is very good.

  • I heard a guy say that there is no center o chess 960. If there is no fighting for control of the center, then most of the action is on the wings? Or the action can happen equally on the center and wings, except for positions where the bishops are on the wings?

Another reason why castling is good in 960 chess (and classical chess) is that it connects the rooks.

In the following example, Black quickly castled and connected his rooks, while White did not. This is not the only reason for White's defeats, but it is part of it.

In chess870, the answer is that the principles of castling in regular chess still apply. This is similar to asking if you should still control the centre, develop knights before bishops, etc.

What I haven't found to be discussed online (or even in Wesley So's chessable course) however is for the 90 positions of chess960 where castling on one side requires moving (or removing by a capture) a rook on the other side.

Sure the principles still apply, but I haven't yet found some article or video that gives some examples explaining whether or not you should give up castling rights on 1 side by moving that side's rook in order to castle on the other side.
