> They are saying those players will see a scenario with two queens of one color on the board every year or two

That makes sense.

It seems to me that you've used a lot of truism reasoning out of frustration. I tried to head these off with my original assumption that it was a question of identity.

>> I anticipate the argument being one of identity, such as "a rook is a rook whether it is right side up or upside down." This is an argument of convention.

Since the reliance is on convention, and an inverted rook is conventionally treated as a promoted queen, the FIDE Arbiters' Manual describes a policy of not following this convention. I'm sure someone knows why this is the guidance. I was curious about that reasoning. It seemed interesting and worthy of discussion.

> You are probably the only person in history from the founding of FIDE until now who has pretended not to know what a rook or a queen is.

You ascribe to pretend ignorance what is in fact interest in the history of a thing. This seems unreasonably antagonistic.

I believe you've misunderstood my original comment and I do not know why, but I think I will be done with this thread. If you find out why this was the adopted guidance for the FIDE Arbiters' Manual I'd enjoy reading about it and I imagine others may too, but it should be put under the original question, not here.
