黑方走棋——找出最佳续着
How to recognize this tactic
A discovered attack fires when one piece steps aside and unmasks the piece behind it. Look for your own units that block a rook, bishop or queen: moving the front piece — ideally with a threat of its own — springs two attacks in one move.
A double attack threatens two things at once so the opponent cannot parry both. Look for a single move — often a queen or knight — that creates two separate threats, such as a check plus an attack on a loose piece.
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 f6, 车 a1 f1, 马 f4, 兵 a2 b2 f3。
黑方:王 g4, 后 c4, 车 h8, 象 b6, 马 d4, 兵 h6 a7 h7。
棋盘上有8枚白棋和8枚黑棋;该题局面出现在第27回合之后。
The position in numbers
White are ahead by 2 points of material (25 against 23; 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 g4.
It is Black to move on move 27, with 2 legal replies to weigh — only the line that keeps the advantage solves the puzzle. Black are in check right now, so every reply must answer the check.
White keeps 3 pawns, Black 3. Files fully open (no pawns of either colour): c, d, e, g — natural highways for the rooks and queen. Half-open for Black: b, f.
The Black king has 1 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
27... Nxf3+ 28. Kh1 Qxf4 29. Qxf4+ Kxf4
为何奏效
- 好棋!马到f3保持压力(+2.6)。
- 好棋!后到f4保持压力(+2.9)。
- 好棋!王到f4保持压力(+2.7)。
- 你赢得一子——后。
- 若改走Kh1,则Qxf4,你赢得马。
Move by move
- 27… Nxf3+ — 马 to f3 (capture) with check
- 28. Kh1 — 王 to h1
- Qxf4 — 后 to f4 (capture)
- 29. Qxf4+ — 后 to f4 (capture) with check
- Kxf4 — 王 to f4 (capture)
本题的题型
闪击
一个子闪开,让后面的子发起第二重攻击。
闪击就像拉开幕布:一个棋子离开直线,露出身后的远程棋子发动打击。妙处在于,走开的那个棋子自己还能攻击第二个目标——一步棋,两记重拳。检查你的叠置组合:马或兵的身后站着象或车,透过它们瞄准对方值钱的东西。前面的棋子要跳到最有攻击性的格子——没有第二威胁的闪击损失一半威力。
反击
别忙着防守——用更大的威胁回敬对手。
反击:面对威胁你的回应不是防守,而是自己的威胁——更强的那种。趁对手吃你的兵,你宣布将杀:这笔账算在你这边。当直接防守都不好时寻找反击:你有没有将军、攻后的手段、做杀的威胁?新手的错误是对每个威胁都条件反射地防守,从不先查一查对攻资源。
双将
两个子同时将军——只有走王才能应对。
双将:两个棋子同时将军——刚走的那个,加上它身后闪出的那个。垫子和吃掉将军者都无济于事——面对两路将军,唯一的解法是走王。寻找这样的闪将:前面的棋子自己也能将军。这是国际象棋中最具强制性的一步:哪怕把后送到对方嘴边也没关系——没人有空吃它。
