What is a gambit in xiangqi, and is an early sacrifice ever sound?
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.

Direct answer
A gambit is an early, deliberate material offer in exchange for faster development, a stronger attack, or control of key lines. A handful are genuinely sound with correct follow-up play, but most opening sacrifices in practice only succeed because the opponent does not find the best defence, not because the material is truly compensated.
What makes a gambit actually sound
A sound one gives you something concrete and lasting in return, such as a permanently exposed enemy general, a piece that stays passive for the rest of the game, or an attack that keeps generating threats faster than the opponent can consolidate. If the compensation depends purely on the opponent making a mistake, it is a practical try rather than a genuinely sound idea.
Why beginners should be cautious with them anyway
Evaluating whether compensation is real requires exactly the calculation and judgement skills that are still developing early on, which makes it easy to play a gambit, lose the material, and never actually get the attack that was supposed to justify it. Playing solid, principled openings until your tactical calculation is reliable is the safer route.
Related questions
Are gambits common in top-level xiangqi?
Less common than in club-level or fast games, since strong opponents defend accurately enough to blunt most unsound sacrifices.
What should I do if my opponent offers a gambit I don't understand?
Decline material you cannot safely hold only if accepting clearly loses control; otherwise take the material and defend carefully rather than assuming the sacrifice must be correct.
