黑方走棋——找出最佳续着
How to recognize this tactic
A discovered attack fires when one piece steps aside and unmasks the piece behind it. Look for your own units that block a rook, bishop or queen: moving the front piece — ideally with a threat of its own — springs two attacks in one move.
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 g1, 后 e7, 车 d1, 兵 f2 h2 g3 d6。
黑方:王 h8, 后 d7, 车 d8, 兵 b6 h6 a7 g7。
棋盘上有7枚白棋和7枚黑棋;该题局面出现在第31回合之后。
The position in numbers
Material is level — 18 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g1, the black king on h8.
It is Black to move on move 31, with 27 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 4. Files fully open (no pawns of either colour): c, e — natural highways for the rooks and queen. Half-open for Black: d, 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
31... Qxe7 32. dxe7 Rxd1+ 33. Kg2 Re1
为何奏效
- 好棋!后到e7保持压力(+6.9)。
- 好棋!车到d1保持压力(+7.1)。
- 好棋!车到e1保持压力(+7.6)。
- 你赢得一子——后。
- 若改走dxe7,则Rxd1+,你赢得后。
Move by move
- 31… Qxe7 — 后 to e7 (capture)
- 32. dxe7 — 兵 to e7 (capture)
- Rxd1+ — 车 to d1 (capture) with check
- 33. Kg2 — 王 to g2
- Re1 — 车 to e1
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。
简化
换掉重子,把局面导入赢定的残局。
简化是兑现优势的技术:兑掉后和车,你就掐灭了对方的反扑,把对局引入赢定的残局。规则简单:子力占优的一方兑子,但保兵。当子力已经赢到手、对手还在虚张声势时,就去找兑换。错误做法是回避兑后,任由对手用没完没了的威胁搅浑水。
