How to recognize this tactic
A hanging piece is one that is attacked and not defended, or defended too few times. Count attackers against defenders on each enemy unit; where attackers win, take it — often with an in-between move or a check to gain the extra tempo.
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 g1, 后 f4, 车 e1, 象 b6, 兵 b2 f2 g2 c3 h3 a4。
黑方：王 h8, 车 e5 d7, 象 g7, 兵 f5 a6 g6 b7 e7 h7。
棋盘上有10枚白棋和10枚黑棋；该题局面出现在第34回合之后。
The position in numbers
White are ahead by 4 points of material (23 against 19; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g1, the black king on h8.
It is Black to move on move 34, with 26 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 — natural highways for the rooks and queen. Half-open for Black: c.
The Black king has 1 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
34... Rxe1+ 35. Kh2 Be5 36. Qxe5+ Rxe5
为何奏效
- 好棋！车到e1保持压力（+7.1）。
- 好棋！象到e5保持压力（+7.2）。
- 好棋！车到e5保持压力（+7.6）。
- 你赢得一子——后。
- 若改走Kh2，则Be5，你赢得车。
Move by move
- 34… Rxe1+ — 车 to e1 (capture) with check
- 35. Kh2 — 王 to h2
- Be5 — 象 to e5
- 36. Qxe5+ — 后 to e5 (capture) with check
- Rxe5 — 车 to e5 (capture)
本题的题型
消除保护者
先吃掉守卫——再拿下它保护的目标。
消灭守卫是最直白的计划：先干掉看守，再拿走它守护的东西。与引离不同，守卫不是被支走的——而是被就地兑掉或消灭。盯着你想吃的目标问：谁在保护它？这个保护者能不能被划算地吃掉？要计算整串吃子的最终得失，而不是只看第一步——这笔交换必须以最后的战利品回本。
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。
