How to recognize this tactic
An uncastled king in the centre is a standing target. Look for ways to open the central files and diagonals against it with checks and threats before it can shelter — every tempo the king spends in the middle is a chance for a combination.
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.
In Chess960 the pieces start on unfamiliar squares, so tactics appear earlier and from unusual angles. Do not trust classical patterns — read the actual lines of the bishops, the rooks and the queen from where they really stand in this position.
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 d1, 后 g8, 车 c1 h1, 象 d2 b3, 马 f4, 兵 c2 g2 h2 e3 f3。
黑方：王 d8, 后 a2, 车 c8, 象 e8, 马 d7, 兵 b4 g5 f6 a7 e7 h7。
棋盘上有12枚白棋和11枚黑棋；该题局面出现在第19回合之后。
The position in numbers
White are ahead by 7 points of material (33 against 26; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on d1, the black king on d8.
It is White to move on move 19, with 43 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 6. Files fully open (no pawns of either colour): d — natural highways for the rooks and queen. Half-open for White: a, b.
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
马杀
马以它独一无二的角度送出致命一击。
马杀：最后一击由马完成——它是唯一无法用垫挡化解将军的棋子。正因如此，马对被挤住的国王格外致命：只有走王或吃掉马本身才有救。识别特征：国王周围的格子被占据或受控，而存在一个马能安然无恙地跳过去将军的格子。提前把马调往前线：它比远程棋子慢，但它的打击无法招架。
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。
未易位之王
王在中路磨蹭——惩罚这种拖延。
惩罚未易位的王：对手拖延易位——他的王困在出发格上挨打。在 Chess960 中这比古典棋更危险：王可能站在中央，也可能靠边，习惯的防守套路统统失灵。识别特征：受害者还保有易位权，而通向他王的直线已半开。要赶在国王藏好之前打开线路。
