# How do I convert two chariots against a chariot and a cannon?

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
>
> The side with two chariots holds a real, generally winning material edge, but the defending side's cannon is not nothing, it provides genuine tactical counterplay a bare extra chariot against nothing would not have to deal with. The practical technique is to **trade off the defender's chariot** when a clean opportunity appears, since **two chariots against a lone cannon** converts far more simply than the mixed material does.

## Why the cannon makes this harder than a simple piece-up endgame

Unlike a bare extra chariot against nothing, here the defender has an active piece that can create real threats, particularly if it finds a screen near your own general or an uncoordinated piece. Treating the position as automatically simple, the way a plain material count might suggest, is the main way this kind of advantage gets thrown away.

## Why simplifying to two chariots versus one cannon is the target

Once the defending chariot is gone, the remaining lone cannon has no way to generate serious resistance against two coordinated chariots, and the technique becomes close to a standard mating exercise. See [converting two chariots against one](https://xiangqimaster.com/blog/converting-two-chariots-versus-one-chariot) for the closely related simpler case this position is usually trying to reach.

## Related questions

Should I avoid all trades to keep more attackers on the board?

No, the opposite is usually true here: trading the defender's most active piece, the chariot, is what actually simplifies the win.

Is the cannon dangerous to my king in this endgame?

It can be if you are careless about screens near your own general, so keep that in mind even while you are the side pressing for the win.
