白方走棋——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.
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 g5, 象 f1, 兵 g2 h2 c3 e3 d4 e5。
黑方:王 f7, 后 a5, 车 f8, 象 b3, 兵 c4。
棋盘上有9枚白棋和5枚黑棋;该题局面出现在第38回合之后。
The position in numbers
Material is level — 18 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g1, the black king on f7.
It is White to move on move 38, with 25 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 1. Files fully open (no pawns of either colour): a, b, f — natural highways for the rooks and queen.
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
38. e6+ Kxe6 39. Qxa5
为何奏效
- 好棋!兵到e6保持压力(+7.0)。
- 好棋!后到a5保持压力(+7.1)。
- 你赢得一子——后。
- 若改走Kxe6,则Qxa5,你赢得后。
Move by move
- 38. e6+ — 兵 to e6 with check
- Kxe6 — 王 to e6 (capture)
- 39. Qxa5 — 后 to a5 (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。
腾挪
带着先手把自己的子挪开,为决定性一击腾出线路。
让路:决定性打击被你自己的棋子挡住了——那就把它挪开,甚至干脆送掉。关键是带节奏地让路:闪开时带着将军、吃子或威胁,让对手来不及重新布防。识别特征:你看到后或车有一记好杀招,但需要的线路或格子被自己的棋子占着。别舍不得——让路的弃子通常比错失的攻势便宜得多。
