In the opening, soldiers are mostly blockers and screens. In the middlegame, one question starts to matter more and more: can I get a soldier across the river safely? A crossed soldier gains sideways movement, gets closer to the enemy palace, and often becomes the extra unit that wins the endgame. But soldiers never retreat, so every advance is a permanent decision.
What changes when a soldier crosses
Before the river, a soldier moves only forward. After crossing, it can also move one point sideways. That turns it from a slow blocker into a piece that:
- controls three points instead of one,
- approaches the palace from different angles,
- restricts the enemy general once it stands near the palace,
- supports other pieces' landing points near the palace,
- provides screens for cannons in enemy territory.
That is why many players count a crossed soldier as roughly twice a soldier at home.
When to advance a soldier across the river
When it is safe
The most basic condition: the soldier must not simply be captured. On the enemy side of the river it will face chariots, cannons and horses. Before advancing, check what attacks the point it will land on and whether you can defend it.
When it gains something concrete
Good reasons to cross:
- It attacks a piece — a horse, cannon or an unprotected soldier.
- It opens a file for your chariot when it advances or is exchanged.
- It takes a key point from which the opponent's horse would like to jump.
- It prepares the endgame by creating an extra unit close to the palace.
When the opponent cannot easily attack it
A crossed soldier that the opponent must spend two or three moves to win is often worth the investment, even if it eventually falls — the time gained can be used elsewhere.
How to support a crossed soldier
A lone crossed soldier is a target. Typical support:
- A chariot behind it on the same file protects it and also pushes forward if the soldier is captured.
- A horse covering its point makes capturing it costly.
- A second soldier beside it — two crossed soldiers side by side protect each other when they have both crossed.
- A cannon on the file can recapture through the soldier's attacker in some positions.
Where crossed soldiers belong
The best posts for a crossed soldier are usually near the enemy palace but not on the last rank:
- the rank in front of the enemy palace, where it attacks palace points,
- the rank level with the front of the palace, where it restricts the general and supports attacks,
- beside the palace, where it takes escape points away from the general.
The last rank is usually a poor post: the soldier can only move sideways there and no longer threatens the palace from the front. Players call such a soldier an "old soldier". Stop your soldiers before they get old. See soldiers in xiangqi.
Crossed soldiers in attack
In the late middlegame, a crossed soldier near the palace is a powerful helper:
- It takes away escape points from the general, so your chariot or horse can mate with fewer moves.
- It supports a chariot landing on the second rank.
- It blocks the enemy's horse legs or elephant eyes near the palace, reducing the defense.
- It provides a screen for your cannon to check along a rank or file.
Many mating attacks in real games include a soldier as the quiet partner that nobody paid attention to.
Crossed soldiers and the endgame
When pieces come off, crossed soldiers become even more valuable. Endgames like chariot plus soldier against chariot, or horse plus soldier against a weakened defense, are often winning where the same material without the soldier would be drawn. A player who crosses a soldier safely in the middlegame is often preparing a winning endgame without the opponent noticing.
Stopping the opponent's soldiers
- Block them before the river. A soldier at home is easy to attack. Chariots and cannons on your own river bank discourage advances.
- Use elephants. Elephants cover the points in front of your palace where crossed soldiers want to land.
- Trade them. Capturing or exchanging an advanced soldier early is often cheaper than dealing with it later.
- Keep your general mobile. A soldier next to your palace often attacks escape points. Leaving your general room to move prevents mating patterns.
An example in words
In a quiet middlegame, Red's chariot stands on file 3, a few points behind Red's soldier on the same file. Red advances the soldier two steps and it crosses the river. Black's horse wanted to use the point the soldier now attacks, so the horse must stay back. Black tries to win the soldier with its cannon, but Red's chariot behind the soldier protects it. Red then brings a horse to support the soldier's next step.
Ten moves later, after several exchanges, Red has a horse and a crossed soldier near Black's palace against Black's horse and a palace missing one elephant. The soldier takes away one escape point; Red's horse and general do the rest. The game was decided by a soldier move that looked modest at the time.
Common mistakes
Advancing without support. A crossed soldier with nothing behind it is usually lost.
Advancing too many soldiers. Each advance weakens the points behind it and uses time. One or two well-supported crossed soldiers are better than four loose ones.
Pushing to the last rank. Old soldiers are weak. Stop one step earlier.
Ignoring the opponent's crossed soldier. It looks harmless until it takes your general's last escape point.
Practice
Play games against the computer on the home page with the goal of getting one soldier across the river by move twenty, supported by a chariot or horse. Watch how it affects the endgame. More middlegame ideas are in how to make a plan and the middlegame section.
Frequently asked questions
How much is a crossed soldier worth?
A common rough guide counts it at about twice a soldier at home. Near the enemy palace and well supported, it can be worth even more.
Should I cross soldiers early in the game?
Usually not in the first few moves. In the middlegame, cross when it is safe and gains something concrete.
Why not push the soldier all the way to the end?
On the last rank it can only move sideways and loses most of its attacking power.
What is the best piece to support a crossed soldier?
A chariot behind it on the same file is the most common and effective support.
Can a crossed soldier be protected by a cannon?
Sometimes. A cannon on the same line can recapture only if exactly one piece stands between the cannon and the capturing enemy piece, so check the screen count before relying on it.
