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 d1, 车 e2, 象 c2。
黑方:王 f2, 车 d4, 兵 d2 g3。
棋盘上有3枚白棋和4枚黑棋;该题局面出现在第66回合之后。
The position in numbers
White are ahead by 1 points of material (8 against 7; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on d1, the black king on f2.
It is Black to move on move 66, with 3 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 0 pawns, Black 2. Files fully open (no pawns of either colour): a, b, c, e, f, h — natural highways for the rooks and queen.
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
66... Kf3 67. Bb3 g2 68. Rxg2 Kxg2
为何奏效
- 好棋!王到f3保持压力(+4.6)。
- 好棋!兵到g2保持压力(+4.4)。
- 好棋!王到g2保持压力(+5.1)。
- 你赢得一子——车。
- 若改走Bb3,则g2,你仍占优。
Move by move
- 66… Kf3 — 王 to f3
- 67. Bb3 — 象 to b3
- g2 — 兵 to g2
- 68. Rxg2 — 车 to g2 (capture)
- Kxg2 — 王 to g2 (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。
通路兵
通路兵已无人能挡——护送它冲到底线。
通路兵:前方和相邻两列都没有敌兵的兵——能拦住它的只有棋子。查一查谁能堵在它路上、谁的王能追上它——如果谁也不能,它就值一整个子。推进通路兵要有棋子支援,车要放在它身后。新手的错误是毫无支援地把兵直推到对方嘴边。
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。
