黑方走棋——找出最佳续着
How to recognize this tactic
Deflection drags a defender away from its duty. Identify the enemy piece that guards a key square or mate, then force it to move — with a check, a capture or a threat it must answer — and strike where it no longer defends.
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 a6, 象 b7, 兵 c5。
黑方:王 b8, 马 e8, 兵 a7。
棋盘上有3枚白棋和3枚黑棋;该题局面出现在第65回合之后。
The position in numbers
Material is level — 4 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on a6, the black king on b8.
It is Black to move on move 65, with 5 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 1 pawns, Black 1. Files fully open (no pawns of either colour): b, d, e, f, g, h — natural highways for the rooks and queen. Half-open for Black: c.
The Black king has 1 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
65... Nc7+ 66. Ka5 Kxb7
为何奏效
- 好棋!马到c7保持压力(+6.7)。
- 好棋!王到b7保持压力(+6.7)。
- 你赢得一子——象。
- 若改走Ka5,则Kxb7,你赢得象。
Move by move
- 65… Nc7+ — 马 to c7 with check
- 66. Ka5 — 王 to a5
- Kxb7 — 王 to b7 (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。
轻子残局
象与马的对决——几何决定胜负。
轻子残局:盘上只剩象、马和兵,几何决定一切。象喜欢开放的棋盘和两翼作战,马喜欢固定的兵和支撑点。看看兵都站在什么颜色的格子上,马来不来得及赶到关键区域。实用建议:对付马就把战火引向两翼——短腿跑不过来。
