What is the technique for a horse and soldier endgame?
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
Use the soldier to restrict the defence while the horse manoeuvres patiently toward a square that actually threatens something. Horse and soldier is one of the combinations that forces mate against a bare general, and the practical skill is keeping the horse's legs clear while the soldier does the quieter work of denying the general options.
Why the horse needs patience
A horse takes several moves to reach any specific square and can be blocked by a single piece on an adjacent point, including the defending general itself in a bare endgame. Route it around obstacles rather than forcing a blocked path.
What the soldier contributes
Beyond any material value, a soldier near the palace covers escape points the horse cannot reach on its own, which is frequently what turns a horse check into an actual mate. Treat it as part of the mating net, not a separate asset, the same way it does in any crossed soldier endgame.

Is this easier or harder than a chariot mate?
Harder in general, because neither piece controls a whole line the way a chariot does.
Does this technique work against a real defence?
Against a full defence of advisors and elephants it is much harder and often not forcing at all.
