for people who confused about how the game work
as far as i know the main pieces is still black and white
but when a main piece step on a colored tile, the piece with that color will be controlled by the player with the piece on the tile until that piece goes away
you can only have 1 piece on each color
and when a side is controlling a specific color, the tile with that color can't be access by the other side
pawn go to around the middle will turn into queen and i don't really know exactly how
