Picture a Knight at one corner of a rectangle three squares by two: its move lands at the diagonally opposite corner. How does that curious leap fit into the battle for a King? In this early-20th-century guide, Edward Lasker begins with the contest’s precise laws: how the pieces move, how a King escapes check, and what it means to be checkmated. From the opening formation of sixteen forces on each side, he leads into the language players use to record a game and the principles that make sound judgment more valuable than memorized moves. Every square offers a choice; every move can change the balance of the fight. How can a player learn to see not just the next move, but the plan taking shape across the board?
