白方走棋——找出最佳续着
How to recognize this tactic
Deflection drags a defender away from its duty. Identify the enemy piece that guards a key square or mate, then force it to move — with a check, a capture or a threat it must answer — and strike where it no longer defends.
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 e2, 车 a1 a8, 象 d5, 兵 b2 c3。
黑方:王 h8, 车 g3 f8, 象 d3, 兵 b3 c5 e5 d6 h7。
棋盘上有6枚白棋和9枚黑棋;该题局面出现在第35回合之后。
The position in numbers
Black are ahead by 3 points of material (15 against 18; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e2, the black king on h8.
It is White to move on move 35, with 3 legal replies to weigh — only the line that keeps the advantage solves the puzzle. White are in check right now, so every reply must answer the check.
White keeps 2 pawns, Black 5. Files fully open (no pawns of either colour): a, f, g — natural highways for the rooks and queen. Half-open for White: d, e, h.
The White king has 3 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
35. Kd2 Kg7 36. R1a7+ Kh6 37. Rxf8
为何奏效
- 好棋!王到d2保持压力(+3.8)。
- 好棋!车到a7保持压力(+3.7)。
- 好棋!车到f8保持压力(+3.7)。
- 你赢得一子——车。
- 若改走Kg7,则R1a7+,你仍占优。
Move by move
- 35. Kd2 — 王 to d2
- Kg7 — 王 to g7
- 36. R1a7+ — 车 to a7 with check
- Kh6 — 王 to h6
- 37. Rxf8 — 车 to f8 (capture)
本题的题型
绝对牵制
一个子被牵制在王前——按规则它根本不能动。
绝对牵制:一个棋子被冻结在自己国王与你的远程棋子之间的直线上——按规则它根本不许移动。特征是三个单位排在一条直线上:你的象、车或后,敌方棋子,以及它身后的敌方国王。被牵制的棋子既不能进攻也不能防守,就当它不在棋盘上。放心地再次攻击它,最好用兵——它无权逃跑。
残局战术
残局里同样有战术——子力稀少时照样出击。
战术不会随着后的兑换而退休:捉双、牵制和双重攻击在残局里照样活跃。子力所剩无几,因此这里每一次战术损失几乎都直接定胜负。特征还是老几样:无保护的棋子、王与棋子同线、即将升变的兵。建议:即使在「纯技术」残局里,每步棋前也要搜一遍战术——自己的和对方的。
救子
被攻击的子不但能救,还能顺手赚一笔。
救子:你的棋子被攻击,任务是别白白送掉它。办法有几种:带节奏地撤退、加以保护、垫挡攻击,或制造更凶的对攻威胁。机械后撤之前,先找带反击的撤退——既救了子又赚了时间。典型错误是惊慌失措逃到随便一个格子,结果棋子又被抓住。
