About this position
In Spanish it is called the kick mate, because the knight delivers it like a horse’s kick against a king hemmed in by its own pieces. It is a very old pattern: it already appears in Luis Ramírez de Lucena’s book, published around 1497. In English, one of its best-known versions is called Philidor’s Legacy, although Lucena recorded it centuries earlier. It usually happens to a king that has gone to the corner after short, with the pawns in front unmoved and its own pieces blocking the exits. The signs to look for are a king with no free squares and an enemy knight that can reach a checking square. To defend, give your king a way out in time: one pawn moved in front of the castled king is often enough to stop the knight from finishing.
