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.
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 f1, 后 d6, 车 c1, 象 g3, 兵 b2 f2 c4 g4。
黑方：王 h7, 后 c6, 车 f7, 马 h2, 兵 c5 a6 e6 g6 h6。
棋盘上有8枚白棋和9枚黑棋；该题局面出现在第33回合之后。
The position in numbers
Black are ahead by 1 points of material (21 against 22; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on f1, the black king on h7.
It is White to move on move 33, with 4 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 4 pawns, Black 5. Files fully open (no pawns of either colour): d — natural highways for the rooks and queen. Half-open for White: a, e, h.
The White 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
33. Bxh2 Qh1+ 34. Bg1
为何奏效
- 好棋！象到h2保持压力（+2.4）。
- 好棋！象到g1保持压力（+2.4）。
- 你赢得一子——马。
- 若改走Qh1+，则Bg1，你赢得马。
Move by move
- 33. Bxh2 — 象 to h2 (capture)
- Qh1+ — 后 to h1 with check
- 34. Bg1 — 象 to g1
本题的题型
制胜一击
找到那记强制得子的妙击。
制胜一击：强制赢得子力，却不归入任何单一的教科书主题。通用的战术配方在此适用：找出无保护的棋子、站位别扭的国王、超载的线路。按力度顺序枚举强制着法：将军、吃子、威胁——绝大多数组合正是从其中之一开始。不要凭感觉评估：把具体变化算到结果确凿无疑为止。
