黑方走棋——找出最佳续着
How to recognize this tactic
A pin freezes a piece in front of a more valuable one behind it. Scan the ranks, files and diagonals your bishop, rook or queen controls: if an enemy piece cannot move without exposing its king or queen, it is pinned and can be piled on or bypassed.
Here the task is defensive: one of your pieces is under attack and must be rescued without losing more. Look for a move that saves it with tempo — a counter-check, an equal counter-attack or an interposition — rather than a passive retreat.
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 h3, 后 e4, 象 c7, 兵 a2 h2 c3 f3 d4 g4。
黑方：王 g6, 后 e2, 马 e3, 兵 g5 b6 f6 a7 h7。
棋盘上有9枚白棋和8枚黑棋；该题局面出现在第36回合之后。
The position in numbers
White are ahead by 1 points of material (18 against 17; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h3, the black king on g6.
It is Black to move on move 36, with 5 legal replies to weigh — only the line that keeps the advantage solves the puzzle. Black are in check right now, so every reply must answer the check.
White keeps 6 pawns, Black 5. Files fully open (no pawns of either colour): e — natural highways for the rooks and queen. Half-open for Black: c, d.
The Black 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
36... Kh6 37. Qxe3 Qxe3
为何奏效
- 好棋！王到h6保持压力（+7.3）。
- 好棋！后到e3保持压力（+7.3）。
- 你赢得一子——后。
- 若改走Qxe3，则Qxe3，你赢得后。
Move by move
- 36… Kh6 — 王 to h6
- 37. Qxe3 — 后 to e3 (capture)
- Qxe3 — 后 to e3 (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。
后残局
开放棋盘上的皇后大战——精确高于一切。
后残局阴险难测：后无处不达，一个不准就把胜势变成长将和棋。主题特征：兵很少、王暴露、连环将军的味道飘在空中。提前把王藏好，并利用自己的将军带节奏地调后靠近、或推进通路兵。错误做法是只顾吃兵，把王丢给无穷无尽的将军。
救子
被攻击的子不但能救，还能顺手赚一笔。
救子：你的棋子被攻击，任务是别白白送掉它。办法有几种：带节奏地撤退、加以保护、垫挡攻击，或制造更凶的对攻威胁。机械后撤之前，先找带反击的撤退——既救了子又赚了时间。典型错误是惊慌失措逃到随便一个格子，结果棋子又被抓住。
