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.
This is a forced mating attack. Start from the enemy king: which of its squares are already covered, and which move takes away the rest while keeping the king in check? Forcing moves — checks and captures — are what turn an attack into mate.
A mate in four is a longer forced net: each of your moves is a check or an irresistible threat, and the king is driven step by step to a square where it is finally trapped. Verify that the defender has exactly one reply at every branch.
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 e2, 后 c5, 车 b2, 象 h1, 兵 f2 h2 a4 g5。
黑方:王 e8, 后 e5, 车 g8, 兵 a5 h6 b7 f7。
棋盘上有8枚白棋和7枚黑棋;该题局面出现在第31回合之后。
The position in numbers
White are ahead by 3 points of material (21 against 18; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e2, the black king on e8.
It is White to move on move 31, with 8 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 4 pawns, Black 4. Files fully open (no pawns of either colour): c, d, e — natural highways for the rooks and queen. Half-open for White: b.
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
31. Qxe5+ Kd8 32. Qd6+ Ke8 33. Bc6+ bxc6 34. Rb8#
为何奏效
- 好棋!后到e5保持压力(#3)。
- 最佳着法。后到d6正是引擎的选择(#2)。
- 最佳着法。象到c6正是引擎的选择(#1)。
- 最佳着法。车到b8正是引擎的选择(#)。
- 该变着以4步强制将杀结束。
- 若改走Kd8,则Qd6+,你赢得后。
Move by move
- 31. Qxe5+ — 后 to e5 (capture) with check
- Kd8 — 王 to d8
- 32. Qd6+ — 后 to d6 with check
- Ke8 — 王 to e8
- 33. Bc6+ — 象 to c6 with check
- bxc6 — 兵 to c6 (capture)
- 34. Rb8# — 车 to b8 and it is checkmate
本题的题型
四步以上杀
一段长长的强制杀王组合。
四步以上的将杀是一场强制着法的马拉松,一刻也不能松手。依靠仍是那些工具:将军、双重威胁和弃子,不给对手一个自由的节奏。别想同时抱住整棵变化树:先把主线算到将杀,再核对旁支。如果对手在某处找到一步不丢子的安静防守——说明你的第一步就错了。
关于这个局面
这些棋子来自起始局面 #603。
SP-603 · ThroneGuard — 两只马都在内侧线 (b–g),国王居中于 d 或 e——本家族共 204 个局面之一。
王起始于 d1,两车在 a1 与 f1,后在 b1。
王翼车已经站在 f1,所以短易位只动王:由 d1 到 g1。
一只象起始于角落 h1:它只有一条斜线,由 g 线兵打开,直通 a8。
有一个第二横线的兵开局时完全无人保护:h2。
该摆法属于 ThroneGuard 家族;从右往左读,它就成为第 257 号局面。
引擎主变以 d3 开始。
莫罗佐夫均衡指数:86/100 — 等级 A — 最均衡。 引擎对起始局面的评估:白方 +15 厘兵(深度 47,400 000 000 节点)。
