Solution move by move

  1. 1. Red R4+1 (captures the Advisor, check, sacrifices the Chariot, threatens mate next move, the only legal reply)
    Why it works
    • Forcing: the opponent has only one reply, so the line cannot be avoided.
    • Wins material: takes the Advisor.
    • Creates an immediate mating threat that must be answered.
    What to watch out for
    • Gives up the Chariot; the follow-up must be exact or the sacrifice is wasted.
