Kling and Horwitz: The King Blockades

White to play and draw, after Kling and Horwitz, 1851

Play

Connected passers on g5 and h6 usually win, but the black king has already sat down in front of them on g6. This is the most important drawn position of the connected-pawns family, and it is worth memorizing from both sides.

The theory

Connected passers are strong because they advance. A king planted in front of them stops that, and the whole advantage evaporates.

The blockade. With the defending king on the square ahead of the pawns, neither pawn can move and neither can be defended forward. A lone rook cannot drive that king away.

Kling and Horwitz, 1851. This is the reference position for the whole theme. If you can reach it as the defender you draw, and if you allow it as the attacker you have thrown away the win.

In this drill you play the stronger side and learn to see the drawn blockade for what it is instead of pushing into a loss.
