What is the best defence against the chariot crossing the river?

Offering a trade of chariots at the right moment. It takes the most dangerous attacker off the board while Black's defensive structure stays whole.

Is this attack sound or just scary?

It is sound and it is standard. Against accurate defence it leads to a balanced middlegame rather than a forced win, which is still an excellent practical result for Red.

Why does crossing the river matter so much in xiangqi?

Pieces in the opponent's half attack more and are harder to chase, and soldiers that cross gain the ability to move sideways. The river is a real dividing line, not decoration.

Central Cannon, Chariot Crosses the River

中炮过河车 · zhōng pào guò hé chē

This is what the Central Cannon was building toward. Red lines up the chariot and sends it across the river to press Black's horse while the screen is still settling, and suddenly every one of Black's moves has to answer something. It is the most direct attacking plan in the game, it wins an enormous number of club games outright, and it has one honest answer that every Black player needs to know.

Why crossing the river is so strong

A chariot in the opponent's half attacks soldiers, horses and defenders at once, and it does so from a distance where very few pieces can chase it away. In xiangqi there are no pawns that shoulder rooks aside; an intruding chariot usually has to be met by another chariot.

That is exactly why the plan works so well against an unprepared defence. If Black's second chariot is still at home when Red's arrives, Black is defending with pieces that were never meant to defend.

The attack, move by move in plain terms

Put the chariot on the file where it can travel without being harassed.
Cross the river and attack the horse that holds Black's structure together.
Bring the second attacker, normally the other chariot or the cannon that is not in the middle.
Break on the file where Black has one defender fewer than Red has attackers.

How Black defends

Offer the trade of chariots. This is the main answer and it is not cowardice, it is the point: every trade removes an attacker and leaves the defence intact.
Do not move the screen horses to escape. Breaking your own structure is how a pressure position becomes a lost one.
Develop the last chariot before it is forced. A defender that arrives on its own terms is worth two that arrive in check.

Practise it on a real board

This structure rewards repetition more than any other opening in xiangqi, because the attacking and defending patterns repeat almost move for move from game to game. Play it from both sides, twenty times each, and it becomes instinct.

Try it on a real board

Reading an opening and playing one are different skills. Set this line up against the computer, get it wrong a few times cheaply, then take it into a rated game.
