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.
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 c2, 象 f5, 兵 c3 d4 g4。
黑方:王 c4, 象 b7, 兵 c5 d5 g5。
棋盘上有5枚白棋和5枚黑棋;该题局面出现在第59回合之后。
The position in numbers
Material is level — 6 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on c2, the black king on c4.
It is White to move on move 59, with 13 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 3 pawns, Black 3. Files fully open (no pawns of either colour): a, b, e, f, h — natural highways for the rooks and queen.
The White king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.

本题的题型
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。
轻子残局
象与马的对决——几何决定胜负。
轻子残局:盘上只剩象、马和兵,几何决定一切。象喜欢开放的棋盘和两翼作战,马喜欢固定的兵和支撑点。看看兵都站在什么颜色的格子上,马来不来得及赶到关键区域。实用建议:对付马就把战火引向两翼——短腿跑不过来。
