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 d6, 车 e7 e8, 兵 b4 b5。
黑方:王 b6, 车 c3 h3, 兵 d3 g6。
棋盘上有5枚白棋和5枚黑棋;该题局面出现在第46回合之后。
The position in numbers
Material is level — 12 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on d6, the black king on b6.
It is White to move on move 46, with 24 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 2 pawns, Black 2. Files fully open (no pawns of either colour): a, c, e, f, h — natural highways for the rooks and queen. Half-open for White: d, g.
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
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。
车残局
最常见的残局——一切取决于子力的活跃度。
车残局是实战中最常见的残局:盘上是车和兵。第一法则是积极性:站在通路兵身后的车,胜过消极守兵的车。正确计划的标志——你的车在攻击什么,而不是在看守什么。错误做法是把车锁死在护兵岗位上:常常宁可丢一兵,也要保住活跃的车和活跃的王。
