Go (game)
Two players, "Black" and "White", take turns placing a "stone" (game piece) of their own color on a vacant "point" (intersection) of the grid on a Go board. Black plays first. If there is a large difference in skill between the players, the weaker player typically uses Black and is allowed to place two or more stones on the board to compensate for the difference (see Go handicaps). The official grid comprises 19×19 lines, though the rules can be applied to any grid size. 13×13 and 9×9 boards are popular choices to teach beginners, or for playing quick games. Once placed, a stone may not be moved to a different point.
Hasami shogi
In this variant each player starts the game with 18 pieces occupying their two nearest ranks. Since most shogi sets have only 9 pawns for each side, this game is usually played using black and white Go stones. Additionally, one-quarter (9×9 grid) of a Go board can be used in lieu of a shogi board. All the move and capture rules of Variant 1 apply, but the winning objective is different, and a jumping move is possible.
