> **屏風馬** — "folding screen horses" — is the standard answer to the Central Cannon. Both horses come to the points beside the central file, **defending the central soldier** and standing side by side like a screen. It defends and develops with the same moves, which is why it is the most played defence in the game.

## Why it answers the Central Cannon so well

A Central Cannon's first threat is the central soldier. 馬8進7 defends it *and* develops a piece, so Black loses no time answering — which is the whole problem with every other reply. The second horse follows, and Black has two developed pieces and a solid centre.

## What comes after

Black opens a file for a chariot and contests the centre. The resulting middlegames are the most heavily analysed in xiangqi, and they are the reason this pairing is what most players should learn first: between Central Cannon and Screen Horses you learn both how attacks are built and how they are stopped.
