How to recognize this tactic
This position hides a concrete tactic that wins material or mates. Start with the most forcing candidate moves — checks, captures and threats — and calculate each to a clear end before choosing; the winning line is usually the one the opponent cannot meet.
In Chess960 the pieces start on unfamiliar squares, so tactics appear earlier and from unusual angles. Do not trust classical patterns — read the actual lines of the bishops, the rooks and the queen from where they really stand in this position.
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 c5, 车 g1, 象 d1 e1, 马 d2, 兵 a2 b2 h2 h3 f5。
黑方:王 g8, 后 c6, 车 h6, 象 e8, 马 d4, 兵 a7 b7 g7。
棋盘上有11枚白棋和8枚黑棋;该题局面出现在第20回合之后。
The position in numbers
White are ahead by 5 points of material (28 against 23; 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 g8.
It is White to move on move 20, with 6 legal replies to weigh — only the line that keeps the advantage solves the puzzle. White are in check right now, so every reply must answer the check.
White keeps 5 pawns, Black 3. Files fully open (no pawns of either colour): c, d, e — natural highways for the rooks and queen. Half-open for White: g.
White hold the bishop pair, an edge in open lines. The White king has 0 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
20. Qxc6 Bxc6+ 21. Rg2 Rxh3 22. Bg3
为何奏效
- 好棋!后到c6保持压力(+3.4)。
- 好棋!车到g2保持压力(+3.3)。
- 合理的出子:象到g3。
- 你获得制胜局面(+3.2)。
- 若改走Bxc6+,则Rg2,你仍占优。
Move by move
- 20. Qxc6 — 后 to c6 (capture)
本题的题型
后的捉双
皇后落在一个能同时攻击两个目标的格子上。
后沿直线、横线和斜线出击,因此她比任何棋子都更容易形成捉双。寻找这样的格子:后从那里同时攻击两个无保护的目标——最常见的是将军外加一个悬子。斜线打击尤其致命:斜向将军同时瞄准角落里的车,是这一主题的经典。请记住:两个目标都必须无保护,否则你的「捉双」只是放空枪。
唯一着法
其他任何一步都会输——找到唯一撑得住的那一步。
唯一着法:除了独一无二的那步棋,其余全输的局面。这里不能「顺手」下棋:把原则上不同的防守都过一遍——逃跑、垫挡、兑换、反击——再淘汰被驳倒的。这类题目的标志:显而易见的着法很快就输,而正解常常看起来古怪。先弄清威胁你的究竟是什么——那步唯一的防守自会现身。
