黑方走棋——找出最佳续着
How to recognize this tactic
Deflection drags a defender away from its duty. Identify the enemy piece that guards a key square or mate, then force it to move — with a check, a capture or a threat it must answer — and strike where it no longer defends.
A skewer is a pin reversed — the valuable piece stands in front and, when it moves, the piece behind falls. Line your rook, bishop or queen up against the king or queen and win whatever is hiding behind it.
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 h3, 后 h8, 兵 a2 b2 h2 g3 e5。
黑方：王 f7, 后 e2, 兵 d5 g5 a7 b7。
棋盘上有7枚白棋和6枚黑棋；该题局面出现在第27回合之后。
The position in numbers
White are ahead by 1 points of material (14 against 13; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h3, the black king on f7.
It is Black to move on move 27, with 28 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 4. Files fully open (no pawns of either colour): c, f — natural highways for the rooks and queen. Half-open for Black: e, h.
The Black 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
27... g4+ 28. Kh4 Qxh2+ 29. Kxg4 Qxh8
为何奏效
- 好棋！兵到g4保持压力（+8.9）。
- 好棋！后到h2保持压力（+9.2）。
- 好棋！后到h8保持压力（+9.1）。
- 你赢得一子——后。
- 若改走Kh4，则Qxh2+，你仍占优。
Move by move
- 27… g4+ — 兵 to g4 with check
- 28. Kh4 — 王 to h4
- Qxh2+ — 后 to h2 (capture) with check
- 29. Kxg4 — 王 to g4 (capture)
- Qxh8 — 后 to h8 (capture)
本题的题型
串击
线路攻击逼走价值高的子，暴露出它身后的目标。
串击是反过来的牵制：贵重的棋子站在前面，便宜的躲在它身后。大子被迫让开——你就吃掉躲在它影子里的那个。搜寻与另一枚己方棋子同线（直线、横线或斜线）的敌方国王或后。最凶狠的版本带将军：国王一让开，它身后的车就没命了。
后残局
开放棋盘上的皇后大战——精确高于一切。
后残局阴险难测：后无处不达，一个不准就把胜势变成长将和棋。主题特征：兵很少、王暴露、连环将军的味道飘在空中。提前把王藏好，并利用自己的将军带节奏地调后靠近、或推进通路兵。错误做法是只顾吃兵，把王丢给无穷无尽的将军。
突破
弃兵撕开兵链，让通路兵冲出去。
突破：一次兵的牺牲撕开对方兵链，制造出无法阻挡的通路兵。到兵与兵顶死的地方寻找它：常常是送掉两个兵，让第三个溜过去。核对方格：对方的王追不追得上新通路兵——追不上就大胆牺牲。错误做法是在敌王就站在旁边、能通吃一切时强行突破。
