Zones of Action

Inspired from Lines of Action.

Setup

For starting position, Stones must be placed on the first row closest to that player. King may be placed in any arrangement on any empty square.

White Stone: a1 b1 c1 d1 e1 f1 g1 h1 White King: any empty square

Black Stone: a8 b8 c8 d8 e8 f8 g8 h8 Black King: any empty square

Pieces

Each player has One King and Eight Stones.

King may jump to any empty square without attacked.

For captruing Opponent's King or moving to an empty square, Stone would make a (x, y) jump as any any-owner stones or Friend's King is in the fomer's {x, y} relative coordinate. (x=0, 1, -1, or 2; y=0, 1, -2, or 2)

Rules

1. Players alternate move one of their own pieces.

2. The object of the game is to checkmate Opponent's King.

For example

d4 Stone lets f5 Stone jump like a Knight. f6 Stone lets f5 Stone step like a Wazir.
