黑方走棋——找出最佳续着
How to recognize this tactic
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 c5, 车 g5, 兵 h3 g4。
黑方：王 g3, 车 a6, 兵 c6。
棋盘上有4枚白棋和3枚黑棋；该题局面出现在第56回合之后。
The position in numbers
White are ahead by 1 points of material (7 against 6; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on c5, the black king on g3.
It is Black to move on move 56, with 15 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 2 pawns, Black 1. Files fully open (no pawns of either colour): a, b, d, e, f — natural highways for the rooks and queen. Half-open for Black: g, h.
The Black king has 7 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
56... Ra5+ 57. Kxc6 Rxg5
为何奏效
- 好棋！车到a5保持压力（+4.8）。
- 好棋！车到g5保持压力（+4.8）。
- 你赢得一子——车。
- 若改走Kxc6，则Rxg5，你赢得车。
Move by move
- 56… Ra5+ — 车 to a5 with check
- 57. Kxc6 — 王 to c6 (capture)
- Rxg5 — 车 to g5 (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。
车残局
最常见的残局——一切取决于子力的活跃度。
车残局是实战中最常见的残局：盘上是车和兵。第一法则是积极性：站在通路兵身后的车，胜过消极守兵的车。正确计划的标志——你的车在攻击什么，而不是在看守什么。错误做法是把车锁死在护兵岗位上：常常宁可丢一兵，也要保住活跃的车和活跃的王。
