How to recognize this tactic
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 g1, 后 f3, 车 c1 f1, 象 e3, 马 d1, 兵 a2 b2 g3 f4。
黑方：王 d7, 后 f7, 车 d8 f8, 象 b7, 兵 b6 d6 g6 e7 h7。
棋盘上有10枚白棋和10枚黑棋；该题局面出现在第21回合之后。
The position in numbers
White are ahead by 2 points of material (29 against 27; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g1, the black king on d7.
It is White to move on move 21, with 38 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 5. Files fully open (no pawns of either colour): c — natural highways for the rooks and queen. Half-open for White: d, e, h.
The White king has 4 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. Qxb7+ Ke6 22. Bd4 Qxf4 23. gxf4
为何奏效
- 好棋！后到b7保持压力（+10.3）。
- 合理的出子：象到d4。
- 好棋！兵到f4保持压力（#9）。
- 你赢得一子——后。
- 若改走Ke6，则Bd4，你赢得象。
Move by move
- 21. Qxb7+ — 后 to b7 (capture) with check
本题的题型
悬子
有个子没人保护——直接吃掉它。
悬子就是没有任何保护、可以白吃的棋子。听起来太初级，可业余棋局的多数胜负正是这样决定的。养成习惯：每步棋之前扫一遍全盘，标出所有无保护的棋子——自己的和对方的。典型的错误是在只需弯腰捡礼物的地方，苦苦寻找华丽的组合。
