Two Minor Pieces: The W-Maneuver
Win against perfect defense
Waking the engine…
The theory
The trickiest phase of the bishop and knight mate is the wrong corner. The king dives into a corner the bishop cannot reach, and you must relocate it without ever letting it break free.
Why it is hard. Mate happens only in a corner of the bishop's color. If the king sits in the opposite corner, no checkmate exists there, so you have to march it across the edge.
The W-maneuver. The knight zigzags in a W pattern, controlling the squares just ahead of the king while the bishop and king form a moving cage that shepherds the defender toward the correct corner.
In this drill the defender clings to the safe corner and squirms toward the center at every chance. Execute the W cleanly and the win is guaranteed inside the fifty-move limit.
