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.
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 e2, 象 c5, 兵 a2 c2 g2 b3 h3。
黑方:王 e5, 象 e3, 兵 d4 f4 h5 a6 c6。
棋盘上有7枚白棋和7枚黑棋;该题局面出现在第37回合之后。
The position in numbers
Material is level — 8 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on e2, the black king on e5.
It is Black to move on move 37, with 13 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 5. Files fully open (no pawns of either colour): e — natural highways for the rooks and queen. Half-open for Black: b, g.
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
37... d3+ 38. Kxd3 Bxc5
为何奏效
- 好棋!兵到d3保持压力(+5.4)。
- 好棋!象到c5保持压力(+5.3)。
- 你赢得决定性子力(+5.3)。
- 若改走Kxd3,则Bxc5,你仍占优。
Move by move
- 37… d3+ — 兵 to d3 with check
- 38. Kxd3 — 王 to d3 (capture)
- Bxc5 — 象 to c5 (capture)
本题的题型
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。
轻子残局
象与马的对决——几何决定胜负。
轻子残局:盘上只剩象、马和兵,几何决定一切。象喜欢开放的棋盘和两翼作战,马喜欢固定的兵和支撑点。看看兵都站在什么颜色的格子上,马来不来得及赶到关键区域。实用建议:对付马就把战火引向两翼——短腿跑不过来。
