◇ Just read — no move neededThe slowest kill in the book
马擒单士 — the horse catches the lone advisor — is the classic patience test: two pieces only, and the win is real but measured in dozens of careful moves. The idea is a hunt across the whole board: the horse drives the advisor out of the corner, the king cuts the return path, and each retreat costs the defender one more square. Most losses here come from impatience — from trying to mate in three when the technique wants twenty. Settle in; the engine scores this a clear win, and the technique is older than any engine.
