A chess variation

I'm not sure what to call this variation; possibly Royal Chess.  The idea is to keep the royal family as just a king and a queen.  In order to win you must capture both the king and the queen.  Now since this is true a check would only be called if just the king or just the queen is left.  Also since the queen is so difficult to actually trap a rule will be set in place that once the king is gone, the queen becomes sticken with grief and is only able to move one square at a time, just as the king ussually does.  Now here is where it gets really interesting.  When a pawn promotes. it can't just promote to anything it wants.  If both the king and queen are still alive then the pawn must promote to something else (knight, bishop, rook), however if one is dead they can promote to the other: If you have a king but no queen you can promote to a queen as well, and if you have a queen but no king you can promote to a king.  If you promote to a king, then the queen becomes happy again and can move like normal.  Please comment with ideas or request for clarification if anything is unclear.

It sounds interesting. Does it mean a player would be able to use their King as a "normal" piece, e.g. to go to a square where he would be checked? I think so for it has to be possible to capture the King.

Yes that would be a legal move as long as the queen is still on the board. If only 1 of them is one the board (the king or the king) checking(and checkmating) would work like normal.

I think that game would work on a computer but playing it on a board would be funny since you would have to remember every time what kind of move you can make with the queen. Interesting though.

As long as you kept track it should be fine. Though a computer would definitely be easier since it would keep track of it for you.

I had the same idea last night as this, with exception that you actually just replace the queen with king piece when king is captured.

Idea of promoting to pawn king to relinquish the command back to the new king is interesting too, especially if this is forced that you cannot have second queen before new king is reinstated.

Compared to regular rules, I believe this would allow quite different strategies with king sacrifices and require safeguarding your queen when king gets into trouble.

EDIT: This should be in Chess variants though.
