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.
In a mate in three every move must be forcing; the defender should never get a free tempo. Find the check or threat that herds the king, calculate the single defence to each, and confirm the net closes on the third move.
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.
棋盘上的局面
白方:王 e1, 后 c4, 车 b1 g1, 象 a1 d1, 马 e3 h5, 兵 a2 d2 e2 f2 g2 h2 b4。
黑方:王 e8, 后 c8, 车 b8 g8, 象 a8 d8, 马 g6 h8, 兵 e5 f6 a7 c7 d7 g7 h7。
棋盘上有15枚白棋和15枚黑棋;该题局面出现在第7回合之后。
The position in numbers
Material is level — 38 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on e1, the black king on e8.
It is White to move on move 7, with 53 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 7. No file is fully open, so the heavy pieces have to be pried in. Half-open for White: c.
The White king has 2 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
7. Qxg8+ Nf8 8. Nxg7+ Ke7 9. Nef5#
为何奏效
- 好棋!后到g8保持压力(#2)。
- 好棋!马到g7保持压力(#1)。
- 最佳着法。马到f5正是引擎的选择(#)。
- 该变着以3步强制将杀结束。
- 若改走Nf8,则Nxg7+,你赢得车。
Move by move
- 7. Qxg8+ — 后 to g8 (capture) with check
- Nf8 — 马 to f8
- 8. Nxg7+ — 马 to g7 (capture) with check
- Ke7 — 王 to e7
- 9. Nef5# — 马 to f5 and it is checkmate
本题的题型
马杀
马以它独一无二的角度送出致命一击。
马杀:最后一击由马完成——它是唯一无法用垫挡化解将军的棋子。正因如此,马对被挤住的国王格外致命:只有走王或吃掉马本身才有救。识别特征:国王周围的格子被占据或受控,而存在一个马能安然无恙地跳过去将军的格子。提前把马调往前线:它比远程棋子慢,但它的打击无法招架。
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?
三步杀
三步之内的强制将杀。
三步杀是一道强制的阶梯:你的每一步都收窄对手的选择,第三步画上句号。到将军和弃子中寻找开局之着:杀题里安静的首着虽少见,却格外阴险。脑中要有变化树:每种防守对应自己的分支。别在第二步就停下——最终的将杀图景必须亲眼算到。
关于这个局面
这些棋子来自起始局面 #785。
SP-785 · ThroneScout — 国王位于底线中央,已有一只马被带到角上。
王起始于 e1,两车在 b1 与 g1,后在 c1。
王车易位的终点一如既往:短易位王到 g1、车到 f1;长易位王到 c1、车到 d1。
一只象起始于角落 a1:它只有一条斜线,由 b 线兵打开,直通 h8。
有一个第二横线的兵开局时完全无人保护:a2。
该摆法属于 ThroneScout 家族;从右往左读,它就成为第 171 号局面。
引擎主变以 b4 开始。
莫罗佐夫均衡指数:6/100 — 等级 D — 优势最大。 引擎对起始局面的评估:白方 +48 厘兵(深度 43,400 000 000 节点)。
