白方走棋——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 h1, 后 g4, 车 d1 g1, 象 e3, 兵 b2 f2 h2 a3 e5。
黑方:王 h8, 后 d7, 车 a4 f5, 马 e8, 兵 d5 b6 h6 b7 c7 g7。
棋盘上有10枚白棋和11枚黑棋;该题局面出现在第25回合之后。
The position in numbers
Black are ahead by 1 points of material (27 against 28; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h1, the black king on h8.
It is White to move on move 25, with 46 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 6. No file is fully open, so the heavy pieces have to be pried in. Half-open for White: c, d, g.
The White 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
25. e6 Qxe6 26. Qxa4
为何奏效
- 好棋!兵到e6保持压力(+4.1)。
- 好棋!后到a4保持压力(+4.3)。
- 你赢得一子——车。
- 若改走Qxe6,则Qxa4,你赢得车。
Move by move
- 25. e6 — 兵 to e6
- Qxe6 — 后 to e6 (capture)
- 26. Qxa4 — 后 to a4 (capture)
本题的题型
引离
把防守者从岗位上引开——再攻击它守护的目标。
引离:你迫使守卫离开岗位——用弃子或交换把它从它保护的棋子或格子旁拽走。先找出关键的看守者:少了它,防杀或保子的体系就会崩塌。然后找一步它无法置之不理的棋——最常见的是吃子。别心疼子力:如果守卫离开后你能做杀或吃后,这笔投资会加倍收回。
静着
既不将军也不吃子——但正是这步不起眼的棋决定了胜负。
静着:既不将军也不吃子,却恰恰是它决定胜负——制造无法招架的威胁,或夺走国王最后的格子。这是最难的一类着法:眼睛总在搜寻轰鸣的重击,赢棋的却是一次低调的挪动。线索:所有强制尝试都撞上防守——那就找那步单纯加强威胁或抢占格子的棋。训练自己发问:如果不吃不将,只是静静地加强,会怎样?
