白方走棋——找出最佳续着
How to recognize this tactic
A mate in one hides among forcing checks. Run through every check you can give: does it cover all the king's escape squares, is the checking piece safe or supported, and can nothing block or capture it? If yes, that is the mate.
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 h2, 后 h4, 车 b7, 象 c1 h3, 兵 c3。
黑方：王 e6, 后 a1, 车 f6, 象 g6, 兵 e4 a5 c5 f5 d6 a7 g7。
棋盘上有6枚白棋和11枚黑棋；该题局面出现在第48回合之后。
The position in numbers
Black are ahead by 3 points of material (21 against 24; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h2, the black king on e6.
It is White to move on move 48, with 41 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 1 pawns, Black 7. Files fully open (no pawns of either colour): b, h — natural highways for the rooks and queen. Half-open for White: a, d, e, f, g.
White 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.

本题的题型
肩章杀
王的两侧被自己的子像肩章一样夹住——杀着迎面而来。
肩章杀：国王站在自己两个棋子中间，像戴肩章的军官——最常见的是两侧的双车。两旁的格子被自己人占据，身后无路可退——后从正面贴脸将杀。识别特征：国王在边线横排上，同排两侧的相邻格都被己方棋子占据。请记住：紧贴国王的多余保镖，有时比没有保镖更致命。
一步杀
一步将杀——把它找出来。
一步杀：组合已经落幕，只剩最后一发精准的子弹。方法很简单——列出你所有的将军，对每一个检验国王的三条生路：逃跑、垫挡、吃掉将军者。三条都行不通，那就是将杀。典型错误是爱上找到的第一个将军，漏掉那扇唯一的逃生小窗。
反击
别忙着防守——用更大的威胁回敬对手。
反击：面对威胁你的回应不是防守，而是自己的威胁——更强的那种。趁对手吃你的兵，你宣布将杀：这笔账算在你这边。当直接防守都不好时寻找反击：你有没有将军、攻后的手段、做杀的威胁？新手的错误是对每个威胁都条件反射地防守，从不先查一查对攻资源。
