白方走棋——找出最佳续着
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 g1, 后 b1, 车 c1 e2, 兵 b2 f2 g2 a3。
黑方：王 h8, 后 h3, 车 c5 d8, 象 c6, 马 c7, 兵 b6 g6 h7。
棋盘上有8枚白棋和9枚黑棋；该题局面出现在第32回合之后。
The position in numbers
Black are ahead by 5 points of material (23 against 28; 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 White to move on move 32, with 32 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 3. Files fully open (no pawns of either colour): c, d, e — natural highways for the rooks and queen. Half-open for White: h.
The White 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
32. gxh3 Rg5+ 33. Kh2
为何奏效
- 好棋！兵到h3保持压力（+1.9）。
- 好棋！王到h2保持压力（+2.5）。
- 你赢得一子——后。
- 若改走Rg5+，则Kh2，你赢得后。
Move by move
- 32. gxh3 — 兵 to h3 (capture)
- Rg5+ — 车 to g5 with check
- 33. Kh2 — 王 to h2
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。
解杀
杀棋已成威胁——化解它并保持优势。
解杀：对手离将杀只差一步——但现在轮到你走，这改变了一切。寻找既解除杀棋威胁又保住你优势的防守：常常是一步将军或反威胁，让对方腾不出手来做杀。先准确说出对方要在哪个格子将杀你——否则就是蒙着眼防守。错误做法是走一步实际并没有解除威胁的「防守」。
