白方走棋——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 h2, 后 d6, 车 a1 f1, 象 f2 f3, 马 h4, 兵 c3 h3 a4 c4 e4 g5。
黑方：王 g8, 后 f7, 车 d8 f8, 象 b7, 马 e5 g7, 兵 f4 c5 h5 a6 b6 g6。
棋盘上有13枚白棋和13枚黑棋；该题局面出现在第26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 h2, the black king on g8.
It is White to move on move 26, with 49 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 — natural highways for the rooks and queen. Half-open for White: b, f.
White hold the bishop pair, an edge in open lines. The White king has 3 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
26. Qxe5 Rde8 27. Qd6
为何奏效
- 好棋！后到e5保持压力（+3.2）。
- 好棋！后到d6保持压力（+3.5）。
- 你赢得一子——马。
- 若改走Rde8，则Qd6，你赢得马。
Move by move
- 26. Qxe5 — 后 to e5 (capture)
- Rde8 — 车 to e8
- 27. Qd6 — 后 to d6
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。
