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.
This position hides a concrete tactic that wins material or mates. Start with the most forcing candidate moves — checks, captures and threats — and calculate each to a clear end before choosing; the winning line is usually the one the opponent cannot meet.
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 c1, 后 h1, 车 b1 d1, 象 g1 g2, 马 a1 d3, 兵 c2 d2 e2 h2 g3 a4 f4 a5。
黑方：王 c8, 后 a3, 车 b8 d8, 象 d5 f8, 马 e8, 兵 f5 g6 a7 b7 c7 d7 e7 h7。
棋盘上有16枚白棋和15枚黑棋；该题局面出现在第9回合之后。
The position in numbers
White are ahead by 3 points of material (39 against 36; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on c1, the black king on c8.
It is White to move on move 9, with 2 legal replies to weigh — only the line that keeps the advantage solves the puzzle. White are in check right now, so every reply must answer the check.
White keeps 8 pawns, Black 8. No file is fully open, so the heavy pieces have to be pried in. Half-open for White: b.
The White king has 0 empty squares to step to right now — the fewer they are, the closer a mating net.

主要变着
9. Nb2 Ba2 10. c3 e5 11. fxe5
为何奏效
- 好棋！马到b2保持压力（+3.4）。
- 合理的出子：兵到c3。
- 最佳着法。兵到e5正是引擎的选择（+3.6）。
- 你获得制胜局面（+3.6）。
- 若改走Ba2，则c3，你仍占优。
Move by move
- 9. Nb2 — 马 to b2
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。
挡将救局
带先手挡将——一举扭转局面。
垫将：你用棋子挡住将军，但不是消极地挡，而是带节奏地挡——垫挡的棋子自己制造威胁。这样的垫挡把防守变成进攻。被将军时比较全部三种应法：吃、走王、垫挡——并在垫挡中寻找带反威胁的那一步。错误做法是本可用积极垫挡扭转局面时，机械地走王了事。
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。
