白方走棋——找出最佳续着
How to recognize this tactic
A skewer is a pin reversed — the valuable piece stands in front and, when it moves, the piece behind falls. Line your rook, bishop or queen up against the king or queen and win whatever is hiding behind it.
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 c1, 后 b2, 车 h1, 象 c3, 马 a2, 兵 e3 b4 c5。
黑方:王 g8, 后 e7, 车 a7, 象 c7, 马 g4, 兵 e4 d5 c6 g6。
棋盘上有8枚白棋和9枚黑棋;该题局面出现在第37回合之后。
The position in numbers
Black are ahead by 1 points of material (23 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 c1, the black king on g8.
It is White to move on move 37, with 33 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 3 pawns, Black 4. Files fully open (no pawns of either colour): a, f, h — natural highways for the rooks and queen. Half-open for White: d, g.
The White king has 4 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
37. Rh8+ Kf7 38. Rh7+ Ke8 39. Rxe7+
为何奏效
- 好棋!车到h8保持压力(+4.9)。
- 好棋!车到h7保持压力(+5.1)。
- 好棋!车到e7保持压力(+5.3)。
- 你赢得一子——后。
- 若改走Kf7,则Rh7+,你仍占优。
Move by move
- 37. Rh8+ — 车 to h8 with check
- Kf7 — 王 to f7
- 38. Rh7+ — 车 to h7 with check
- Ke8 — 王 to e8
- 39. Rxe7+ — 车 to e7 (capture) with check
本题的题型
串击
线路攻击逼走价值高的子,暴露出它身后的目标。
串击是反过来的牵制:贵重的棋子站在前面,便宜的躲在它身后。大子被迫让开——你就吃掉躲在它影子里的那个。搜寻与另一枚己方棋子同线(直线、横线或斜线)的敌方国王或后。最凶狠的版本带将军:国王一让开,它身后的车就没命了。
连将追击
步步将军——把王一路追到必败之地。
连将追击:你的每一步都是将军,对手连一秒钟都腾不出来实施自己的计划。国王被赶着满盘跑,直到丢子或撞上致命一击。这类变化最容易计算:每次将军,王只有寥寥几种应法——全部枚举即可。养成习惯:任何尖锐局面的计算都从将军开始,它们是棋盘上最强制的着法。
