Corresponding Squares on Defense
Hold the draw against perfect play
Waking the engine…
The theory
When the pawns are frozen, the outcome depends on a hidden map: each square for one king corresponds to a specific square for the other.
Read the pairs. Work out which of your squares answers each enemy king square. Hold the correct pairing and you always have a safe reply.
No wandering. Straying from the correspondence, even to win a pawn, breaks the system and lets the enemy king penetrate.
In this drill the attacker knows the map cold. Match every move on the corresponding square and hold the draw.
