(NB: I could not verify the solution)

* A generic term for a problem where each side plays a different variant.

** Units ‘shrink’ when they capture (Q⇨R⇨B⇨N⇨P⇨P) and ‘grow’ when they move without capturing (P⇨N⇨B⇨R⇨Q⇨Q). A white Pawn on its 7th rank cannot promote by moving to its 8th rank. If it captures it remain an immobilized Pawn on its 8th rank. If it moves without capturing it ‘grows’ into a Knight on its 8th rank. (For example: wPg7 and bNf8---the white Pawn has only two moves: 1.Pg8N and 1.Pxf8P). The Pawn on 1st rank can make 1, 2 or 3 step non-capturing move and will ‘grow’ into a Knight, as well as two capturing moves and remain a Pawn. An en passant capture is possible after the Pawn’s 2 or 3 step moves. The Pawn also ‘grows’ into Knight. ( For example: wPg1 and bPh4---after 1.Pg4(wSg4) Pxg3(bPg3) e.p.)

*** When a piece (Pawn excluded) leaves a square outside the first and last rows, it leaves a Pawn of the color of the side that played unless 8 Pawns in this color are already on the board.
