# What is the technique for two cannons versus a lone chariot?

These answers restate the rules implemented by our open-source engine, which follows the WXF laws and is regression-tested against the official 110-diagram repetition casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it against the engine before publishing.

> Direct answer
>
> Two **coordinated cannons** are roughly comparable in fighting power to a single chariot, and with careful play they can hold their own or even win, because they can use **one cannon as the other's screen** and create threats on two lines at once, something a single chariot cannot always answer simultaneously.

## Why the coordination matters more than the raw count

Two disorganised cannons that never support each other are considerably weaker than their combined point value suggests, since neither can use the other as a screen and the chariot can pick them off individually. Deliberately stacking or aligning them so one supports the other's line of fire is what actually makes the pairing dangerous.

## What the chariot side should be trying to do

The chariot side generally wants to prevent the two cannons from ever aligning usefully, picking them off separately or forcing trades before they can coordinate a real threat. If the cannons do manage to align against the chariot's general, the position can become genuinely dangerous for the side with the single major piece.

## Related questions

Is this considered a roughly even material fight?

Close to it in points terms, though the practical outcome depends heavily on which side coordinates its pieces better.

Should the cannon side avoid trading one cannon off?

Generally yes, since losing one cannon usually reduces the pair to a single piece clearly weaker than the opposing chariot.
