In the opening game, strategy lies in structure. The board must be shaped with discipline. One must first establish positions in the four corners, then extend diagonally to secure influence. Placing a single stone sets the stage; a two-stone formation allows for a three-space extension, three stones enable a four-space expansion, and when aligned with key positions, one may extend by five. Proximity should not be too rigid; distance should not be too erratic. These are the principles laid down by the masters, the guiding rules for later generations. To abandon them and innovate without understanding is to walk an unknown path. As the ancient verse says: "Many begin well, but few see it through to the end."
