黑方走棋——找出最佳续着
How to recognize this tactic
A fork is one piece attacking two targets at once. Look for a knight, pawn or queen move that lands where it hits the king (or a bigger piece) and a second undefended unit on the same turn — the opponent can save only one.
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 c1, 后 d6。
黑方:王 a3, 车 h3, 马 b4, 兵 a4。
棋盘上有2枚白棋和4枚黑棋;该题局面出现在第83回合之后。
The position in numbers
Material is level — 9 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on c1, the black king on a3.
It is Black to move on move 83, with 15 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 0 pawns, Black 1. Files fully open (no pawns of either colour): b, c, d, e, f, g, h — natural highways for the rooks and queen.
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
83... Rc3+ 84. Kd2 Rd3+ 85. Qxd3+ Nxd3
为何奏效
- 好棋!车到c3保持压力(+5.2)。
- 好棋!车到d3保持压力(+5.7)。
- 好棋!马到d3保持压力(+10.2)。
- 你赢得一子——后。
- 若改走Kd2,则Rd3+,你仍占优。
Move by move
- 83… Rc3+ — 车 to c3 with check
- 84. Kd2 — 王 to d2
- Rd3+ — 车 to d3 with check
- 85. Qxd3+ — 后 to d3 (capture) with check
- Nxd3 — 马 to d3 (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。
