白方走棋——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 c1, 后 a4, 车 d1 h1, 象 e4 h4, 马 c3 f3, 兵 a2 b2 c2 f2 g2 h2。
黑方：王 g8, 后 c7, 车 a8 f8, 象 g4 g7, 马 c6 e7, 兵 e5 g6 h6 a7 b7 f7。
棋盘上有14枚白棋和14枚黑棋；该题局面出现在第14回合之后。
The position in numbers
Material is level — 37 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on c1, the black king on g8.
It is White to move on move 14, with 49 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 6. Files fully open (no pawns of either colour): d — natural highways for the rooks and queen. Half-open for White: e.
The White 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
14. Bxc6 Nxc6 15. Qxg4
为何奏效
- 好棋！象到c6保持压力（+3.0）。
- 好棋！后到g4保持压力（+3.3）。
- 你赢得一子——象。
- 若改走Nxc6，则Qxg4，你赢得象。
Move by move
- 14. Bxc6 — 象 to c6 (capture)
- Nxc6 — 马 to c6 (capture)
- 15. Qxg4 — 后 to g4 (capture)
本题的题型
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。
