18. Push open the window, view the moon
Secrets of the Golden Roc: 18 classical compositions
11 moves
Composition 18: 推窗觀月, "Push open the window, view the moon". Red to move; the printed verdict is 勝. The line is the book's printed solution, kernel-verified.
The block prints 相五進變 here: the 變 marks the printed variation, and the move itself is 相五進三, a deflection sacrifice. The elephant leaves e3 so that the flying-general rule seals e9.
Checkmate on the board, exactly as the book's 勝 claims.
