How to recognize this tactic
A hanging piece is one that is attacked and not defended, or defended too few times. Count attackers against defenders on each enemy unit; where attackers win, take it — often with an in-between move or a check to gain the extra tempo.
General method: before you move, list the forcing candidates — every check, every capture, every direct threat — and calculate those first. The solution to a tactic is almost always among them.
棋盘上的局面
白方：王 g1, 后 d1, 车 a1 f1, 象 e3 c4, 马 f5, 兵 a2 b2 f2 g2 h2 c3。
黑方：王 h8, 后 b6, 车 a8 f8, 象 c5 c8, 马 c6, 兵 f6 a7 b7 c7 g7 h7。
棋盘上有13枚白棋和13枚黑棋；该题局面出现在第16回合之后。
The position in numbers
Material is level — 34 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g1, the black king on h8.
It is Black to move on move 16, with 33 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 6. Files fully open (no pawns of either colour): d, e — natural highways for the rooks and queen.
The Black king has 0 empty squares to step to right now — the fewer they are, the closer a mating net.
解答与讲解
主要变着
16... Bxf5 17. Bxc5 Qxc5
为何奏效
- 好棋！象到f5保持压力（+4.5）。
- 好棋！后到c5保持压力（+4.6）。
- 你赢得一子——象。
- 若改走Bxc5，则Qxc5，你赢得象。
Move by move
- 16… Bxf5 — 象 to f5 (capture)
- 17. Bxc5 — 象 to c5 (capture)
- Qxc5 — 后 to c5 (capture)
本题的题型
制胜一击
找到那记强制得子的妙击。
制胜一击：强制赢得子力，却不归入任何单一的教科书主题。通用的战术配方在此适用：找出无保护的棋子、站位别扭的国王、超载的线路。按力度顺序枚举强制着法：将军、吃子、威胁——绝大多数组合正是从其中之一开始。不要凭感觉评估：把具体变化算到结果确凿无疑为止。
