After learning about liberties and capturing, you're ready to learn one of the most common terms in Weiqi:
Atari.
An atari occurs when a stone or group has only one liberty remaining.
It means the group is one move away from being captured.
Recognizing atari is one of the first tactical skills every beginner should develop.
If you can spot atari quickly, you'll avoid losing your own stones and create opportunities to capture your opponent's.
What Does Atari Mean?
A stone is in atari when it has exactly one liberty left.
If the opponent occupies that final liberty on their next move, the stone or group is captured.
Think of atari as a warning.
Your stones are still alive, but they are in immediate danger.

Atari Applies to Groups Too
Many beginners think atari only applies to a single stone.
It doesn't.
Connected stones share liberties, so an entire group can be in atari.
Whether the group contains one stone or twenty, the rule is exactly the same.
If the group has only one liberty remaining, it is in atari.

How Do You Respond to Atari?
When one of your groups is in atari, don't panic.
Instead, look for ways to create more liberties.
Common responses include:
Extend
Play on the last liberty to give your group more breathing space.
Connect
Join your endangered group to another friendly group that has additional liberties.
Capture First
Sometimes you can capture your opponent's stones before they capture yours.
If doing so creates new liberties, your group survives.
Learning to find these saving moves is an important step toward stronger reading skills.

Giving Atari
Just as you want to avoid atari, you'll also learn to create it.
Putting an opponent into atari forces them to respond.
In many situations, this gives you the initiative because your opponent must deal with the immediate threat.
However, experienced players don't give atari automatically.
Sometimes giving atari actually helps your opponent escape or become stronger.
A good question to ask before playing is:
"What happens after my opponent responds?"
Thinking one move ahead is a habit that will help you improve quickly.
Why Beginners Miss Atari
One reason beginners lose stones unexpectedly is that they stop counting liberties.
Instead, they focus on where they want to attack.
Before every move, make it a habit to ask:
- How many liberties does my group have?
- How many liberties does my opponent's group have?
- Is either group already in atari?
This quick check only takes a few seconds and prevents many simple mistakes.
Atari Is a Warning, Not a Capture
One of the most common misconceptions is that a stone in atari has already been captured.
That isn't true.
A group in atari still has one liberty remaining.
As long as that liberty exists, the group is still alive and may be able to escape.
Capturing only happens after the final liberty is removed.
Common Beginner Mistakes
Ignoring atari
Many beginners simply don't notice when one of their groups has only one liberty left.
Get into the habit of counting liberties regularly.
Assuming every atari should be played
Putting your opponent into atari isn't always the strongest move.
Sometimes a larger strategic move elsewhere is better.
Panicking when you're in atari
Being in atari doesn't mean the game is over.
Often there are several ways to save your stones.
Stay calm and look for extra liberties.
Forgetting to look one move ahead
Before giving atari, ask yourself:
What will my opponent do next?
Strong players think beyond the immediate capture.
Quick Recap
Before moving on, remember these key ideas:
- Atari means a stone or group has one liberty remaining.
- Atari is a warning, not a capture.
- You can often escape by extending, connecting, or capturing first.
- Count liberties before every move.
- Think about your opponent's response before giving atari.
Frequently Asked Questions
Is atari the same as check in chess?
They are similar in one way.
Both warn that something important is under immediate threat.
However, unlike chess, you are not always required to respond to an atari. Sometimes sacrificing stones is the better strategic choice.
Can a large group be in atari?
Yes.
Any connected group can be in atari if it has only one shared liberty left.
Do I always have to save stones in atari?
No.
Sometimes sacrificing a small group allows you to gain more territory elsewhere.
Learning when to save and when to sacrifice is an important strategic skill.
The guide to dead groups in Weiqi explains this idea in more detail.
Should I announce "atari" during a game?
In casual beginner games, some players say "atari" to help their opponent learn.
In most serious games and tournaments, players simply make their move without announcing it.
