黑方走棋——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.
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 e5, 象 g4 d6, 兵 a2 f2 c3 d7。
黑方：王 f7, 象 d5 d8, 兵 c4 b5 g5 c6。
棋盘上有7枚白棋和7枚黑棋；该题局面出现在第47回合之后。
The position in numbers
Material is level — 10 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on e5, the black king on f7.
It is Black to move on move 47, with 15 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 4. Files fully open (no pawns of either colour): e, h — natural highways for the rooks and queen. Half-open for Black: a, d, f.
The Black 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
47... Bf6+ 48. Kf5 Be6+ 49. Ke4 Bxg4
为何奏效
- 好棋！象到f6保持压力（+5.6）。
- 好棋！象到e6保持压力（+5.7）。
- 好棋！象到g4保持压力（+5.9）。
- 你赢得一子——象。
- 若改走Kf5，则Be6+，你仍占优。
Move by move
- 47… Bf6+ — 象 to f6 with check
- 48. Kf5 — 王 to f5
- Be6+ — 象 to e6 with check
- 49. Ke4 — 王 to e4
- Bxg4 — 象 to g4 (capture)
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。
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。
