What is 江湖排局, the street hustler's xiangqi trap positions?
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
江湖排局 ("rivers and lakes set positions") are trick endgame positions set up by park hustlers to win small bets from passersby. They are built to look completely winning for whoever sits down to play them, while the setter, who has memorised the one narrow path through, actually holds a draw or a win.
How the trick works
A hustler sets a position on a portable board, usually showing the challenger a large material lead or an apparently forced mate. The challenger takes the bet because the position looks overwhelming. The real defence is a single narrow sequence the setter has drilled through repetition, often turning on a stalemate trick, a repetition-rule technicality, or a resource the challenger has no reason to expect.
How they differ from the classic composed endgames
Collections like 夢入神機 and 適情雅趣 are honest, published, and meant to teach: the material and the solution are stated plainly. Street 排局 circulate informally, are sometimes altered from known compositions, and are designed to deceive a first-time viewer rather than instruct one. That said, collectors and strong players also study 排局 purely as a genre, appreciating the composition on its own terms once the gambling context is stripped away.
Related questions
Is this considered cheating?
Not in the sense of an illegal move. It is persuasion about a position's true evaluation, similar to a rigged card trick, and it preys on misjudging the position rather than on breaking any rule.
Are these positions ever legitimate puzzles?
Yes. Enthusiasts and composers study the genre for its ingenuity alone, entirely apart from any betting context.
