Two Horses Drinking is the classic example of mating with "weak" pieces. Neither horse is strong alone, but together they check alternately and cover each other's squares, and the general runs out of room.

1. What it is

Two horses working together near the enemy palace:

  • one horse occupies the key square and seals the general's escapes;
  • the other checks and drives the general in a chosen direction;
  • they take turns, so the defender is always on the back foot.

2. What the mate requires

  1. Both horses can move freely, not tied down by enemy pieces;
  2. Their squares protect each other, so neither can be picked off;
  3. The defender's advisors and elephants are incomplete, with no way to answer;
  4. The general has no spare escape squares.

3. A typical sequence

  1. Red's first horse jumps to the flank and controls one escape;
  2. Red's second horse jumps to a checking square, and the general must move;
  3. The first horse checks again and the general retreats once more;
  4. After a few repetitions the general has nowhere to go — mate.

The key: the two horses' squares must overlap, creating a cycle of control.

4. How to defend

  • Occupy the key squares so neither horse can settle;
  • Block the horse leg to stop the approach;
  • Trade a horse — remove one and the mate collapses;
  • Keep advisors and elephants to give the general a spare square.

5. Why it matters

This pattern shows up in reduced middlegames and endgames, and the horses grow in value once the chariots and cannons are gone. It belongs to the horse-mate family alongside the cannon-behind-horse and crouching horse; what sets it apart is the partnership between the two horses.

How to practise: set up two horses against a lone general and drill the alternating checks, then add advisors for the defender and work out how to strip them first.
