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.
A pin freezes a piece in front of a more valuable one behind it. Scan the ranks, files and diagonals your bishop, rook or queen controls: if an enemy piece cannot move without exposing its king or queen, it is pinned and can be piled on or bypassed.
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 b1, 后 d3, 车 g1 h1, 象 h4, 兵 b2 c2 a3 h3 f4 g5。
黑方:王 g8, 后 d5, 车 a8 f8, 象 e6, 兵 c6 h6 a7 b7 f7 g7。
棋盘上有11枚白棋和11枚黑棋;该题局面出现在第22回合之后。
The position in numbers
Material is level — 28 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on b1, the black king on g8.
It is White to move on move 22, with 39 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, e — natural highways for the rooks and queen.
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
22. gxh6 Qxd3 23. Rxg7+ Kh8 24. cxd3
为何奏效
- 好棋!兵到h6保持压力(+3.8)。
- 好棋!车到g7保持压力(+4.0)。
- 好棋!兵到d3保持压力(+4.1)。
- 你获得制胜局面(+4.1)。
- 若改走Qxd3,则Rxg7+,你仍占优。
Move by move
- 22. gxh6 — 兵 to h6 (capture)
- Qxd3 — 后 to d3 (capture)
- 23. Rxg7+ — 车 to g7 (capture) with check
- Kh8 — 王 to h8
- 24. cxd3 — 兵 to d3 (capture)
本题的题型
弃子攻击
舍弃子力,发动决定性的攻击。
弃子攻王:你有意送出子力,为的是掀开王城、发动决定性攻势。当你换来的是实实在在的资产——通向国王的开放线路、赢得的节奏、随时杀入的棋子——弃子才是正确的。识别特征:敌王掩体单薄,你的兵力对准他的老巢,而防守者远水难救近火。铁律是靠计算而不是靠指望:子力一旦送出,就再没有回头路。
简化
换掉重子,把局面导入赢定的残局。
简化是兑现优势的技术:兑掉后和车,你就掐灭了对方的反扑,把对局引入赢定的残局。规则简单:子力占优的一方兑子,但保兵。当子力已经赢到手、对手还在虚张声势时,就去找兑换。错误做法是回避兑后,任由对手用没完没了的威胁搅浑水。
围猎被牵制子
被牵制的子逃不掉——再次攻击它,把它拿下。
被牵制的棋子无法逃跑——这意味着只要再攻击它一次,就能整个赢下它。数一数攻击者和防守者:如果进攻方更多,这个子就是你的了。最好的「第二攻击者」是兵:它比它能吃到的任何东西都便宜。别急着立刻吃——先加强压力,然后再收割。
