黑方走棋——找出最佳续着
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 b3, 车 a1 e1, 象 c4 f4, 马 g6, 兵 a2 b2 f2 g2 h2 c3 d4。
黑方：王 g8, 后 e7, 车 b8 f8, 象 f5 d6, 马 f6, 兵 c6 e6 h6 a7 b7 f7 g7。
棋盘上有14枚白棋和14枚黑棋；该题局面出现在第14回合之后。
The position in numbers
Material is level — 35 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 g8.
It is Black to move on move 14, with 40 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 7. No file is fully open, so the heavy pieces have to be pried in. Half-open for Black: d.
The Black king has 1 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
14... Bxg6 15. Bxd6 Qxd6
为何奏效
- 好棋！象到g6保持压力（+5.1）。
- 好棋！后到d6保持压力（+5.1）。
- 你赢得一子——象。
- 若改走Bxd6，则Qxd6，你赢得象。
Move by move
- 14… Bxg6 — 象 to g6 (capture)
- 15. Bxd6 — 象 to d6 (capture)
- Qxd6 — 后 to d6 (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。
