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 c2, 车 a1 f1, 象 f4 b5, 马 f3, 兵 f2 g2 h2 a3 e4 d5。
黑方:王 g8, 后 d6, 车 a8 e8, 象 g4, 马 e5 b6, 兵 a7 b7 c7 f7 g7 h7。
棋盘上有13枚白棋和13枚黑棋;该题局面出现在第16回合之后。
The position in numbers
Material is level — 34 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 g8.
It is Black to move on move 16, with 52 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 6. No file is fully open, so the heavy pieces have to be pried in. Half-open for Black: d, e.
White hold the bishop pair, an edge in open lines. 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
16... Nxf3+ 17. gxf3 Qxf4
为何奏效
- 好棋!马到f3保持压力(+4.7)。
- 好棋!后到f4保持压力(+4.8)。
- 你赢得一子——象。
- 若改走gxf3,则Qxf4,你赢得象。
Move by move
- 16… Nxf3+ — 马 to f3 (capture) with check
- 17. gxf3 — 兵 to f3 (capture)
- Qxf4 — 后 to f4 (capture)
本题的题型
引入
用弃子把王或某个子引到致命的格子上。
引入是引离的镜像兄弟:你用弃子把国王或棋子拖到致命的格子上。经典手法是弃后或弃车:对方一吃,国王就落入马的捉双、闪将或杀网。先找到目标将被下一击命中的格子,再准备一份它无法拒绝的礼物。要把组合算到底:只有后续着法是强制的,引入才能成立。
腾挪
带着先手把自己的子挪开,为决定性一击腾出线路。
让路:决定性打击被你自己的棋子挡住了——那就把它挪开,甚至干脆送掉。关键是带节奏地让路:闪开时带着将军、吃子或威胁,让对手来不及重新布防。识别特征:你看到后或车有一记好杀招,但需要的线路或格子被自己的棋子占着。别舍不得——让路的弃子通常比错失的攻势便宜得多。
