Rook

Rook had to watch as his king was captured and black took over, now he will infiltrate the fortress where the white king  is being held and break him out. The rules  of war don't apply here so no one will be taking turns here you just have to attack the enemy when they aren't attacking you, plus if the pawns get to the outer wall they will be promoted to a queen and will take Rook. The fight isn't over yet.
