A chess game made by me, goal is to kill every single piece. But, the king has a ability to hop on pieces and do a chain hop like a checkers piece but you can do it in horizontal,vertical and diagonal, but it cant kill pieces that are blocked by the other pieces or the outside of the board or smt. Idk i think theres no new openings because its just the king having a ability so maybe its just the same as chess openings just maybe so tell it in the comments if there is a new opening or not.
