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.
Gonnect
Games between skilled players often end up temporarily deadlocked, since the square Go board allows a "four corners" configuration where neither side can strongly connect; however, since players cannot pass, they eventually must start filling in the internal liberties of their groups. The player who has gained the smallest amount of territory usually loses, so building more territory than your opponent is a means of forcing a connection and winning.
