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 g1, 后 h3, 车 e6, 马 g6, 兵 a2 b2 c2 f2 g2 h5。
黑方：王 c8, 后 b4, 车 d8 g8, 马 a5, 兵 b5 d5 g5 a6 c7。
棋盘上有10枚白棋和10枚黑棋；该题局面出现在第29回合之后。
The position in numbers
Black are ahead by 4 points of material (23 against 27; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g1, the black king on c8.
It is White to move on move 29, with 43 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 5. Files fully open (no pawns of either colour): e — natural highways for the rooks and queen. Half-open for White: d.
The White king has 3 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
29. Re4+ Kb7 30. Rxb4
为何奏效
- 好棋！车到e4保持压力（+4.8）。
- 好棋！车到b4保持压力（+5.3）。
- 你赢得一子——后。
- 若改走Kb7，则Rxb4，你赢得后。
Move by move
- 29. Re4+ — 车 to e4 with check
- Kb7 — 王 to b7
- 30. Rxb4 — 车 to b4 (capture)
本题的题型
闪将
移动的子闪出将军——它自己趁机可以随便吃子。
闪将：棋子走开，露出身后远程棋子的将军。在国王忙于应将的时候，刚才移动的棋子可以为所欲为、毫发无损——哪怕顺手吃掉皇后。寻找与敌王同线的己方远程棋子，且两者之间恰好隔着一枚你的棋子。规则很简单：在所有可选的闪开方式中，挑那个能吃到或攻击到最贵目标的。
