黑方走棋——找出最佳续着
How to recognize this tactic
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.
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 h1, 后 a6, 车 f1, 兵 c2 g2 b3 h4 d5 f5。
黑方：王 g8, 后 d8, 马 g4, 兵 c3 b4 h5 d6 g6。
棋盘上有9枚白棋和8枚黑棋；该题局面出现在第36回合之后。
The position in numbers
White are ahead by 3 points of material (20 against 17; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h1, the black king on g8.
It is Black to move on move 36, with 26 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 5. Files fully open (no pawns of either colour): a, e — natural highways for the rooks and queen. Half-open for Black: f.
The Black 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
36... Qxh4+ 37. Kg1 Qh2#
为何奏效
- 好棋！后到h4保持压力（#1）。
- 好棋！后到h2保持压力（#）。
- 该变着以2步强制将杀结束。
- 若改走Kg1，则Qh2#，即被将杀。
Move by move
- 36… Qxh4+ — 后 to h4 (capture) with check
- 37. Kg1 — 王 to g1
- Qh2# — 后 to h2 and it is checkmate
本题的题型
护卫后杀
皇后贴脸将杀，身后有自己人保护。
有保护的贴身后杀是最常见的将杀图案：后紧贴国王落子，因为有己方棋子或兵保护而成杀。国王无处可逃：吃后不行——那格有保护，而周围所有格子后亲自看管。寻找敌王旁边受保护的格子：有马、象或兵控制它，后的登陆就成了将杀。只需核实一件事：那个格子真有保护，否则国王会直接吃掉后。
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。
