2 If the opening is required, three-handed exchange: at the beginning of the game, black 1 Tianyuan, white 2 plays at one of the eight points around black 1, and black 3 plays with the ball to form one of the above 24 openings. At this time, it's time for the white side. The white side weighed the current situation before hitting the white 4, and can ask for an exchange with the black side, so it becomes black and white 4, and you become. If there is no intention to exchange, put a white 4 on the chessboard. After five hands and two strokes, and four moves in white, when black moves down at 5: 00, choose two points on the chessboard and place the opposite sunspot. White thinks about these two points and asks to remove the points that pose the greatest threat to itself. Three-handed exchange and five-handed play are all for the benefit of white chess. Through five hands and two blows, the opening of some of the above formulas can be transformed into a balanced game.
