Pieces get relativity when they move long ranges
Einstein chess

Pieces, when they are queens, can ONLY transform to lower valued pieces. Kings can't transform, when castling, your rook will transform after you have castled.

There really are no clear rules except in #5, can I suggest some?
Knights and pawns cannot transform
A piece that moves exactly one square transforms from B->R or R->Q
A piece that moves 3+ squares transforms from Q->R or R->B
All transformations occur immediately after the move and determine checks.
Some that I'm not as sure about: Knights flip to Alibaba, King flips to General, pawn promotions are permanent, pawns flip to sergeants
Pieces get relativity when they move long ranges
What if we go explore on this more?

Here is the rules:
Pieces transform into more or less powerful pieces when they move.
