Composition 2: 五虎靠山, "Five tigers lean on the mountain". Red to move; the printed verdict is 勝. The line is the book's printed solution, kernel-verified. This leaf omits the closing 勝 character; the line ends in checkmate on the board regardless.
Checkmate on the board, exactly as the book's 勝 claims.
