Checkmate the queen

The rules are simple--the QUEEN is the most valuable piece, it is one's goal to checkmate her. Pawns can only promote to KINGS. The queen bosses the king around and moves in any direction she wants.

Yeah, another variant with a 99.9% draw rate...

Then Tai Shogi is designed better. There the royal piece is an Emperor, which can teleport directly to any square. The only restriction is that it is not allowed to capture anything that is protected. So there a bare Emperor always loses, as on the next move you would take it with your Emperor, as he has nothing to protect it with.

What counts as protected is a bit complex; basically the termination rules in order of precedence, applied at the start of a turn, are:

1) The side to move wins when he captures an Emperor that just made a capture with a non-Emperor.

2) The side to move loses if he has no Emperor

Thanks for that memo--I have edited it to say what I meant it to say initially (that she bosses the king around). But pawns can only promote to kings.

But I still don't get it. How can pawns promote to kings?

Actually I have seen a clever solution to that, in a variant called 'Caissa Britannia'. There the royal piece is also a Queen. But the trick is that this royal Queen is not allowed to pass through check! This makes it possible to confine one Queen with another, just like you would confine a King with a Queen, and makes it easy to win end-games like QRQ.
