Anyway, the new variant that was inspired by the preceeding episode is as follows. Place a new piece on each new edge file making a 10 x 8 board. Place a pawn in front. The new piece can move like a king but can not capture. When the left most piece and the current right most pawn are on the same square they become a much more powerful piece. It is the same for the right most piece merging with the left most pawn. The new piece does not impede own sliders, but does impede the enemy.
Maybe someone with a 10 x 8 chess engine can give this a try!
rules open for modification!
