Jingxian Shuang Cheng Chess · 景县双承棋
Seven points, two pieces each, one shared between you. On the family's smallest board there is no such thing as a quiet move.
七个点、各两枚子，外加一枚共用——家族里最小的盘，没有一步是闲棋。
两子围堵，棋盘最小
Two pieces each on the smallest board in the family
玩法要点
- 棋子：双方各 2 枚，另有 1 枚公用
- 棋盘：7 点
- 获胜：让对手无棋可走
Quick start
- A player who has no legal move at all — not even the shared piece — loses right away. With so few pieces on such a small board, every move counts.
- Take turns moving one of your own pieces, or the shared piece on the right, one step along a line to an adjacent empty point. No jumping, no capturing.
- If the shared piece was just moved, the other player cannot move it on their very next turn — it becomes movable again once that player has taken one turn with a different piece.
快速上手
- 轮到某一方却无棋可走——连公用棋子也没法动——就算输了。棋子少，棋盘也小，每一步都要想清楚。
- 双方轮流选一枚自己的棋子，或者选右侧那枚公用棋子，沿连线走一步到相邻的空棋点。不能跳跃，也不能吃子。
- 如果刚才走的是公用棋子，下一回合对方不能马上再走它，要等对方走完一步别的棋子之后，公用棋子才能再被动。
Rules
Board and Setup
The board has 7 points: two top corners, two bottom corners, a midpoint above and below, and the shared piece's own point on the right.
One player's 2 pieces start on the top corners, the other player's 2 pieces start on the bottom corners. One more piece — shared by both players — starts on the right.
Movement and the Shared Piece
Take turns moving one of your own pieces, or the shared piece on the right, one step along a line to an adjacent empty point. No jumping, no capturing.
If the shared piece was just moved, the other player cannot move it on their very next turn — it becomes movable again once that player has taken one turn with a different piece.
Winning
A player who has no legal move at all — not even the shared piece — loses right away. With so few pieces on such a small board, every move counts.
The core idea is to use the shared piece together with your own pieces to trap the other side's pieces in a corner.
Timer
Each turn lasts 60 seconds. When time runs out, the turn passes to the other side automatically.
You can change the difficulty anytime in Game Settings.
规则详解
棋盘与开局
棋盘有 7 个棋点：上边两角、下边两角，上下各有一个中点，公用棋子在右侧。
一名玩家的 2 枚棋子摆在上边两角，另一名玩家的 2 枚棋子摆在下边两角。右侧另外放一枚谁都能用的棋子。
行棋与公用棋子
双方轮流选一枚自己的棋子，或者选右侧那枚公用棋子，沿连线走一步到相邻的空棋点。不能跳跃，也不能吃子。
如果刚才走的是公用棋子，下一回合对方不能马上再走它，要等对方走完一步别的棋子之后，公用棋子才能再被动。
谁赢
轮到某一方却无棋可走——连公用棋子也没法动——就算输了。棋子少，棋盘也小，每一步都要想清楚。
围堵的思路：用公用棋子和自己的棋子一起把对方的棋子堵在角落里。
计时
每步限时 60 秒，时间到了会自动换对方走。
可以在"对局设置"里换一个难度，随时都能换。
