白方走棋——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 e4, 车 h8, 兵 g4 e5。
黑方：王 h3, 象 h2 e6, 兵 h6 f7。
棋盘上有4枚白棋和5枚黑棋；该题局面出现在第49回合之后。
The position in numbers
Black are ahead by 1 points of material (7 against 8; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e4, the black king on h3.
It is White to move on move 49, with 14 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 2 pawns, Black 2. Files fully open (no pawns of either colour): a, b, c, d — natural highways for the rooks and queen. Half-open for White: f, h.
Black hold the bishop pair, an edge in open lines. The White king has 4 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
49. Rxh6+ Kxg4 50. Rxh2
为何奏效
- 好棋！车到h6保持压力（+4.7）。
- 好棋！车到h2保持压力（+5.1）。
- 你赢得一子——象。
- 若改走Kxg4，则Rxh2，你赢得象。
Move by move
- 49. Rxh6+ — 车 to h6 (capture) with check
- Kxg4 — 王 to g4 (capture)
- 50. Rxh2 — 车 to h2 (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。
残局战术
残局里同样有战术——子力稀少时照样出击。
战术不会随着后的兑换而退休：捉双、牵制和双重攻击在残局里照样活跃。子力所剩无几，因此这里每一次战术损失几乎都直接定胜负。特征还是老几样：无保护的棋子、王与棋子同线、即将升变的兵。建议：即使在「纯技术」残局里，每步棋前也要搜一遍战术——自己的和对方的。
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。
