小动物的家 🏠
小兔子住在森林里，它需要一个安全的家来躲避大灰狼。如果小兔子的家有两扇门，大灰狼堵住一扇，小兔子还能从另一扇逃跑——这个家就是安全的！
但如果小兔子的家只有一扇门，大灰狼把门一堵，小兔子就无处可逃了——这个家就是危险的！
给小朋友：围棋里的棋子就像小动物，它们的家就是"眼"。有两只真眼的家 = 活棋（永远安全）；只有一只真眼的家 = 死棋（最终会被吃掉）！
活棋与死棋的概念
在围棋中，判断一块棋是活是死，是最核心的技能之一。
- 活棋 = 一块棋有两只或两只以上的真眼。对方永远吃不掉，因为对方每次只能堵一个眼，另一个眼永远通着。
- 死棋 = 一块棋被包围住了，做不出两个真眼，也无法和对手形成"双活"。最终会被对方吃掉。
核心口诀：两只真眼是活棋，一只真眼是死棋！
为什么两只眼就死不了？
这是围棋中最神奇的规则之一。想象一下：
- 大灰狼（白棋）想要抓住小兔子（黑棋）
- 小兔子有两个洞（两个真眼）
- 大灰狼每次只能堵住一个洞
- 小兔子从另一个洞逃走了！
无论大灰狼怎么努力，它永远不可能同时堵住两个洞。所以有两只真眼的棋，永远活着！
关键点：这两只眼必须是真眼（完全连通、没有断点）。如果有一只眼是假的，坏人就能从缺口钻进去！
活棋的例子
下面这块黑棋有两只真眼，所以它是活棋。白棋永远吃不掉它。
活棋 ✓
这块棋有两个独立的眼（中间两个空点），所有黑子连成一片。无论白棋怎么下，都不可能同时堵住两个眼。
死棋的例子
下面这块黑棋只有一只真眼，所以它是死棋。白棋最终可以吃掉它。
死棋 ✗
这块棋只有中间一个真眼。白棋只需要慢慢收紧外面的气，最后把唯一的眼睛填掉，整块棋就被吃掉了。
如何做出两眼活棋？
既然两只真眼就能让棋子永远活着，那我们就要学会做活——在自己的棋子里做出两个真眼。
- 第一步：先做出第一个真眼（围出一个空点，周围全是自己的连通棋子）
- 第二步：在附近再做出第二个真眼（两个眼之间要有自己的棋子隔开，不能相通）
两个眼之间的黑子就像一堵墙，把两个眼隔开。这样对方永远不可能同时占据两个眼。
做活口诀：先做一个眼，再做第二个眼。两个眼要分开，中间用棋子隔开！
题目 1：左右两块黑棋分别是活棋还是死棋？
请判断下面左右两块黑棋是活棋还是死棋。
左边
点击查看答案
死棋 ✗ — 只有一个眼（中间空点），是死棋
右边
点击查看答案
死棋 ✗ — 看似有两个眼，其实都是假眼！白墙紧贴在眼位旁边（上下两颗白棋顶住中间空点），白棋可以先下进上面的空点破掉一眼，再吃掉整块。这就是"假两眼"陷阱
题目 2：左右两块黑棋分别是活棋还是死棋？
请判断下面左右两块黑棋是活棋还是死棋。
左边
点击查看答案
活棋 ✓ — 黑棋有两个独立的真眼（左、右两个空点）。白棋下任意一个眼都是自杀（四周全是黑），所以怎么下都吃不掉，是活棋
右边
点击查看答案
死棋 ✗ — 黑棋只有一个真眼（左边那个空点）。按照"一眼是死棋"的定理，如果被白完全包围，最终会被白吃掉
做眼小练习
现在你已经学会了分辨活棋和死棋，试着在棋盘上给自己做出两眼活棋吧！记住口诀：
两只真眼是活棋，一只真眼是死棋！

The Little Animal's Home 🏠
A little bunny lives in the forest and needs a safe home to hide from the big bad wolf. If the bunny's home has two doors, when the wolf blocks one, the bunny can escape through the other — this home is safe!
But if the bunny's home has only one door, the wolf blocks it and the bunny has nowhere to go — this home is dangerous!
For kids: In Go, stones are like little animals and their homes are "eyes." A home with two true eyes = alive (safe forever); a home with only one true eye = dead (will be captured eventually)!
Life and Death Concepts
Judging whether a group is alive or dead is one of the most essential skills in Go.
- Alive = A group with two or more true eyes. The opponent can never capture it, because they can only fill one eye at a time, and the other eye remains open.
- Dead = A group that is surrounded and cannot make two true eyes, nor form a "seki" (dual life). It will eventually be captured.
Core Mantra: Two true eyes = alive, one true eye = dead!
Why Are Two Eyes Unkillable?
This is one of the most magical rules in Go. Imagine:
- The big bad wolf (White) wants to catch the bunny (Black)
- The bunny has two holes (two true eyes)
- The wolf can only block one hole at a time
- The bunny escapes through the other hole!
No matter how hard the wolf tries, it can never block both holes at once. So a group with two true eyes lives forever!
Key Point: Both eyes must be true eyes (solidly connected, no gaps). If one eye is false, the bad guy can sneak in through the gap!
Example of a Living Group
The Black group below has two true eyes, so it is alive. White can never capture it.
Alive ✓
This group has two independent eyes (the two empty points in the middle), and all Black stones are connected. No matter how White plays, both eyes cannot be filled at once.
Example of a Dead Group
The Black group below has only one true eye, so it is dead. White can eventually capture it.
Dead ✗
This group has only one eye in the center. White can slowly reduce the outside liberties and finally fill the only eye, capturing the entire group.
How to Make Two Eyes?
Since two true eyes make a group live forever, we need to learn how to live — making two true eyes within our own stones.
- Step 1: Make the first true eye (surround an empty point with your connected stones)
- Step 2: Make a second true eye nearby (the two eyes must be separated by your stones — they cannot connect)
The stones between the two eyes act like a wall, separating them. This way the opponent can never occupy both eyes at once.
Making Life Mantra: Make one eye first, then make a second. Two eyes must be separate, with stones in between!
Quiz 1: Alive or Dead?
Look at the two Black groups below. Is each alive or dead?
Left
Click to reveal answer
Dead ✗ — Only one eye (the center empty point), so it is dead
Right
Click to reveal answer
Dead ✗ — It looks like two eyes, but both are false eyes! The white wall sits tight against the eye points (top and bottom white stones press into the empty spaces). White can play into the top space first to destroy one eye, then capture the entire group. This is the "fake two eyes" trap
Quiz 2: Alive or Dead?
Look at the two Black groups below. Is each alive or dead?
Left
Click to reveal answer
Alive ✓ — Black has two independent true eyes (left and right empty points). Any White stone placed in either eye is suicide (all four neighbors are black), so the group cannot be captured. Alive
Right
Click to reveal answer
Dead ✗ — Black has only one true eye (the empty point on the left). By the "one eye is dead" theorem, this group will eventually be captured if surrounded
Practice Making Two Eyes
Now that you know how to tell alive from dead groups, try making a two-eyed living group on the board! Remember the mantra:
Two true eyes = alive, one true eye = dead!
You can also open the Tactics Training on the homepage to practice making eyes interactively.
