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 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.
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 b3, 车 a1 d4, 兵 d2 g2 e3 h5 a6 a7。
黑方:王 g8, 后 f2, 车 f3, 象 d7, 马 f6, 兵 c6 h6 f7 g7。
棋盘上有10枚白棋和9枚黑棋;该题局面出现在第34回合之后。
The position in numbers
White are ahead by 1 points of material (25 against 24; 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 g8.
It is White to move on move 34, with 2 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 6 pawns, Black 4. Files fully open (no pawns of either colour): b — natural highways for the rooks and queen. Half-open for White: c, f.
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
34. Kh1 Nxh5 35. a8=Q+
为何奏效
- 好棋!王到h1保持压力(+2.7)。
- 好棋!兵到a8保持压力(+3.9)。
- 你赢得决定性子力(+3.9)。
- 若改走Nxh5,则a8=Q+,你赢得兵。
Move by move
- 34. Kh1 — 王 to h1
- Nxh5 — 马 to h5 (capture)
- 35. a8=Q+ — 兵 to a8 with check
本题的题型
升变
兵冲到底线升变为后——一锤定音。
升变:兵抵达底线变成后,整个局面的评估瞬间改写。在战术中,通路兵很少能白白走到底——通常要靠弃子为它开路。计算节奏:兵到升变格还差几步,防守方来得及拦截吗?还要盯住升变格本身——它必须在敌子够不着的地方,或能被你的组合强行夺下。
关于这个局面
这些棋子来自起始局面 #438。
SP-438 · RampartGuard — 国王在翼侧 (b/g),两只马都在内侧线。
王起始于 g1,两车在 a1 与 h1,后在 e1。
王已经站在易位后的格子上,所以短易位只动车:由 h1 到 f1。
两只象位于 c1 与 f1;只要 d 线兵与 e 线兵让路,它们的长斜线便可直达 h6 与 a6。
有一个第二横线的兵开局时完全无人保护:c2。
该摆法属于 RampartGuard 家族;从右往左读,它就成为第 710 号局面。
引擎主变以 d4 开始,一步把兵推入中心。
莫罗佐夫均衡指数:26/100 — 等级 C — 优势明显。 引擎对起始局面的评估:白方 +34 厘兵(深度 47,400 000 000 节点)。
