How to recognize this tactic
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.
Early Chess960 traps punish natural but careless development. Look for a forcing move that exploits a piece the opponent has just placed on a poor square — a fork, a pin or a threat that wins material before either side is fully developed.
From some Chess960 setups a bishop or queen rakes a long diagonal straight from move one. Trace those long-range lines into the enemy camp: a single opened file or diagonal can create an immediate pin, skewer or mating threat.
Mate in two usually opens with a forcing move — a check, a capture or an unstoppable threat — that strips the king of squares or defenders, so the follow-up mate becomes unavoidable. Look for the first move that leaves the opponent only losing replies.
A set-up fork needs one preparing move before the fork lands — a check that drives the king onto the forking square, or a capture that lines the targets up. Find the preparation first, then the fork it makes possible.
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.
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.

The position in numbers
Material is level — 39 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on b1, the black king on b8.
It is White to move on move 4, with 32 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 8 pawns, Black 8. No file is fully open, so the heavy pieces have to be pried in.
The White king has 0 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
4. Qxb7+ Nxb7 5. Na6#
为何奏效
- 好棋!后到b7保持压力(#1)。
- 好棋!马到a6保持压力(#)。
- 该变着以2步强制将杀结束。
- 若改走Nxb7,则Na6#,即被将杀。
Move by move
- 4. Qxb7+ — 后 to b7 (capture) with check
- Nxb7 — 马 to b7 (capture)
- 5. Na6# — 马 to a6 and it is checkmate
本题的题型
闷杀
王被自己的子埋住——只有马能够到它。
闷杀:国王被自己的军队活活闷死——周围的格子全被己方棋子占据,而将杀由不需要开放线路的马完成。经典流程:马将军,国王躲进角落,弃后逼车堵死最后一格——马跳出,将杀。寻找被自己人围住的角落之王,以及一跳可达的马位。别心疼后:在这个图案里她只是替马开门。
远程首发
远程子力从不寻常的初始格出发,一击横贯整个棋盘。
远程首发:象、车或后直接从出发区域打穿整个棋盘。在 Chess960 中远程棋子站在陌生的位置上,一步兵着就可能打开直捣敌营深处的火线。开局阶段用目光描一遍每枚远程棋子的斜线和直线——自己的和对方的。错误做法是推兵之前不检查:这一步打开的是谁的线路?
两步杀
两步之内的强制将杀。
两步杀:你走一步,对方任意应一步,然后是致命一击。从最强制的首着开始:将军和弃子,把对手的选择压到最少。对他的每一种应法,你都必须备好将杀——所有回应都要检查,一个不漏。常见的失误是算清了漂亮的防守,却忘了那个平淡无奇的。
关于这个局面
这些棋子来自起始局面 #958。
SP-958 · RampartGuard — 两只马都从内侧线起始,而国王位于翼侧 (b/g);镜像孪生在本家族中始终成对。
王起始于 b1,两车在 a1 与 c1,后在 h1。
从 b1 出发,王走出 Chess960 短易位所能有的最长路程:五格到 g1。
两只象位于 f1 与 g1;只要 e 线兵与 f 线兵让路,它们的长斜线便可直达 a6 与 a7。
有一个第二横线的兵开局时完全无人保护:d2。
该摆法属于 RampartGuard 家族;从右往左读,它就成为第 4 号局面。
引擎主变以 e4 开始,一步把兵推入中心。
