In endgames many players assume that full advisors and elephants means an automatic draw. With the right coordination, however, cannon plus a high soldier can force a win. This guide explains the key ideas and the order of play.

1. Why the high soldier matters

A soldier's value changes dramatically with its position:

  • Before crossing the river it can only move forward and does little;
  • Just across the river it can move sideways and starts to threaten;
  • A high soldier (near the enemy back rank) presses on the palace, seals the general's escapes and can even check directly.

Cannon plus high soldier beats full advisors and elephants precisely because of the soldier's pressure on the general combined with the cannon's long-range binding. In other words, the soldier's position is the lifeline of this endgame.

2. How cannon and soldier cooperate

The cannon and soldier are an excellent pair:

  • The cannon captures over a screen: using the soldier or the enemy's advisors and elephants as a screen, it threatens the general from a distance and makes the defenders afraid to move;
  • The soldier closes in step by step: each advance squeezes the general's room and creates more space for the cannon;
  • The general joins in: Red's general takes the central file at the right time to restrict the black general, completing a three-piece net.

The core: the cannon binds, the soldier seals, the general controls the general.

3. The typical winning order

  1. Push the soldier high first. The further forward, the bigger the threat — this is the precondition.
  2. Use the cannon to control the central or rib file. Occupy the key points, restrict the general and advisors, and look for chances to hit an elephant or advisor.
  3. Force an elephant or advisor off its post. Use the cannon's threat and the soldier's advance to make the defenders crowd each other.
  4. Strike through the gap. The moment the shell cracks, check with the cannon or soldier and mate.

4. Key points for both sides

Attacker:

  • Keep pushing the soldier — do not leave it stranded halfway;
  • The cannon must always threaten the general, never make empty moves;
  • Bring the general to the central file in time to increase control.

Defender:

  • Block the cannon's lines with advisors and elephants as far as possible;
  • Use the general to drive back or restrain Red's soldier;
  • Keep the defenders connected so they cannot be picked off one by one.

5. Common mistakes

  • Advancing the soldier too slowly: the moment passes, the defence reorganises and the game is drawn;
  • The cannon acting alone: checking with the cannon without support from the soldier or general rarely wins;
  • Ignoring the general: without it on the central file the attacking power is insufficient, and a won position slips away.

6. How to practise

Set up cannon and high soldier against full advisors and elephants in our endgame editor and drill it:

  1. Aim to win in the fewest moves and feel the rhythm of "soldier first, cannon binding after";
  2. Move the soldier to different heights (high and low) and compare the results;
  3. Once comfortable, try variants such as cannon and low soldier to understand how position changes the outcome.
