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 d1, 后 d4, 车 a1 g1, 象 b1, 马 g7, 兵 b2 a3 e3 f3 c4 h4 e5。
黑方：王 d8, 后 c7, 车 a8 f8, 象 e8, 马 e7, 兵 a5 f5 h5 e6 b7 d7。
棋盘上有13枚白棋和12枚黑棋；该题局面出现在第21回合之后。
The position in numbers
White are ahead by 1 points of material (32 against 31; 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 21, with 41 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 6. Files fully open (no pawns of either colour): g — natural highways for the rooks and queen. Half-open for White: d.
The White king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.
解答与讲解
主要变着
21. Nxe6+ Kc8 22. Nxc7 Kxc7 23. Qd6+
为何奏效
- 好棋！马到e6保持压力（+7.8）。
- 好棋！马到c7保持压力（+8.2）。
- 最佳着法。后到d6正是引擎的选择（+8.4）。
- 你赢得一子——后。
- 若改走Kc8，则Nxc7，你赢得后。
Move by move
- 21. Nxe6+ — 马 to e6 (capture) with check
本题的题型
王室捉双
带将军的捉双：王必须躲开，另一个子就丢了。
王家捉双是带将军的捉双：两个目标之一是国王本身。国王必须首先应将，因此没有人、也没有时间去救第二个棋子。寻找这样的格子：你的棋子从那里将军，同时攻击无保护的后或车。这是最可靠的捉双——对手根本没有选择的余地。
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。
