黑方走棋——找出最佳续着
How to recognize this tactic
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 h1, 后 e7, 车 g1 b7, 马 h2, 兵 a2 f3 e4 d5。
黑方:王 h4, 后 e3, 车 c2 f4, 兵 e5 d6 g6 h6 a7。
棋盘上有9枚白棋和9枚黑棋;该题局面出现在第32回合之后。
The position in numbers
White are ahead by 2 points of material (26 against 24; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h1, the black king on h4.
It is Black to move on move 32, with 4 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 4 pawns, Black 5. Files fully open (no pawns of either colour): b, c — natural highways for the rooks and queen. Half-open for Black: f.
The Black king has 2 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
32... Kh3 33. Qe6+ Rf5 34. Rg3+ Kxg3
为何奏效
- 好棋!王到h3保持压力(+5.0)。
- 好棋!车到f5保持压力(+5.2)。
- 好棋!王到g3保持压力(+5.4)。
- 你赢得一子——车。
- 若改走Qe6+,则Rf5,你仍占优。
Move by move
- 32… Kh3 — 王 to h3
- 33. Qe6+ — 后 to e6 with check
- Rf5 — 车 to f5
- 34. Rg3+ — 车 to g3 with check
- Kxg3 — 王 to g3 (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。
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。
王的撤离
王迈开自己的脚步走出危险区。
国王撤离:掩体既已坍塌,王就徒步走出攻击区——有时要横穿半个棋盘。一连串精确的王着把他带出火力圈,对手的攻势随之消散。识别特征:没有一种直接防守管用,但存在一条经过安全格、通往棋盘僻静角落的路线。要提前算好全程——半路抛锚的王通常就死在半路。
