How to recognize this tactic
A hanging piece is one that is attacked and not defended, or defended too few times. Count attackers against defenders on each enemy unit; where attackers win, take it — often with an in-between move or a check to gain the extra tempo.
Here the task is defensive: one of your pieces is under attack and must be rescued without losing more. Look for a move that saves it with tempo — a counter-check, an equal counter-attack or an interposition — rather than a passive retreat.
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, 车 f1, 马 d6, 兵 a2 b2 c2 h2 g3 f6。
黑方:王 c7, 车 d8, 象 b7, 兵 a6 c6 e6 g6 h6。
棋盘上有9枚白棋和8枚黑棋;该题局面出现在第26回合之后。
The position in numbers
White are ahead by 1 points of material (14 against 13; 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 c7.
It is Black to move on move 26, with 20 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): d — natural highways for the rooks and queen. Half-open for Black: b, f.
The Black 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
26... Kxd6 27. Rd1+ Kc7
为何奏效
- 好棋!王到d6保持压力(+4.2)。
- 好棋!王到c7保持压力(+4.2)。
- 你赢得一子——马。
- 若改走Rd1+,则Kc7,你赢得马。
Move by move
- 26… Kxd6 — 王 to d6 (capture)
- 27. Rd1+ — 车 to d1 with check
- Kc7 — 王 to c7
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。
唯一着法
其他任何一步都会输——找到唯一撑得住的那一步。
唯一着法:除了独一无二的那步棋,其余全输的局面。这里不能「顺手」下棋:把原则上不同的防守都过一遍——逃跑、垫挡、兑换、反击——再淘汰被驳倒的。这类题目的标志:显而易见的着法很快就输,而正解常常看起来古怪。先弄清威胁你的究竟是什么——那步唯一的防守自会现身。
王的行军
残局中王就是战斗力——大胆带它上前线。
王的进军:在残局里王是战斗单位,取胜的常常正是他的向前远征。当后已兑掉、将军不足为惧时,就该进军了:王攻击兵、护送通路兵、抢占格子。主题特征——连续好几步都是王在走。按方格法则提前算好路线,别让对方的王抢到对王。
