黑方走棋——找出最佳续着
How to recognize this tactic
Mate in two usually opens with a forcing move — a check, a capture or an unstoppable threat — that strips the king of squares or defenders, so the follow-up mate becomes unavoidable. Look for the first move that leaves the opponent only losing replies.
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, 后 e6, 车 e8, 兵 a2 b2 g4 f5。
黑方:王 h7, 后 g3, 象 g5, 兵 d5 a6 c6 h6 b7 g7。
棋盘上有7枚白棋和9枚黑棋;该题局面出现在第39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 d1, the black king on h7.
It is Black to move on move 39, with 34 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 6. Files fully open (no pawns of either colour): e — natural highways for the rooks and queen. Half-open for Black: f.
The Black king has 0 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
39... Qd3+ 40. Ke1 Bh4#
为何奏效
- 好棋!后到d3保持压力(#1)。
- 好棋!象到h4保持压力(#)。
- 该变着以2步强制将杀结束。
- 若改走Ke1,则Bh4#,即被将杀。
Move by move
- 39… Qd3+ — 后 to d3 with check
- 40. Ke1 — 王 to e1
- Bh4# — 象 to h4 and it is checkmate
本题的题型
两步杀
两步之内的强制将杀。
两步杀:你走一步,对方任意应一步,然后是致命一击。从最强制的首着开始:将军和弃子,把对手的选择压到最少。对他的每一种应法,你都必须备好将杀——所有回应都要检查,一个不漏。常见的失误是算清了漂亮的防守,却忘了那个平淡无奇的。
解杀
杀棋已成威胁——化解它并保持优势。
解杀:对手离将杀只差一步——但现在轮到你走,这改变了一切。寻找既解除杀棋威胁又保住你优势的防守:常常是一步将军或反威胁,让对方腾不出手来做杀。先准确说出对方要在哪个格子将杀你——否则就是蒙着眼防守。错误做法是走一步实际并没有解除威胁的「防守」。
