Go beginners make surprisingly similar mistakes. That is good news: once you know them, you can spot them in your own games and fix them one by one. Here are ten of the most common, grouped by theme, each with a practical fix.
Mistakes with capturing
1. Answering every atari
When a stone is put in atari, beginners almost always extend it. But if the stone will simply be put in atari again, you are feeding the opponent more prisoners. A stone chased along the edge or into a wall of enemy stones is often better abandoned.
Fix: before extending, count the liberties you will have after the extension. If the answer is "two, and the opponent can atari again", consider playing elsewhere.
2. Missing your own atari
The opposite mistake: not noticing that one of your groups has just been reduced to one liberty.
Fix: after every opponent move, look at the stones it touches. It takes two seconds and saves whole groups. Liberties and capturing explains the habit in detail.
3. Chasing stones that cannot escape
Beginners love to chase. But chasing a group that is already dead, or that will escape anyway, just adds your stones to the area without purpose.
Fix: ask what the chase gains. If it makes your wall stronger or gains territory, fine; if not, play something bigger.
Mistakes with shape and connection
4. Leaving cutting points everywhere
Two stones linked only diagonally can be cut. Many beginner groups are full of such weaknesses, and a single cut splits them into two weak groups.
Fix: when a cut would really hurt, make a solid connection. When it would not, leave it — but know which is which.
5. Playing too close to your own stones
Stones placed right next to each other are safe but slow. They claim little area. This is sometimes called "heavy" or "overconcentrated" play.
Fix: in the opening, space your stones apart — a jump of one or two points along the third or fourth line is common.
6. Crawling on the first or second line
When pressed against the edge, beginners crawl along the first or second line, gaining a point per move while the opponent builds a big wall above.
Fix: avoid low crawling unless it saves an important group. Get your stones onto the third and fourth lines early.
Mistakes with the whole board
7. Starting in the centre
The centre looks important, but on a big board it is hard to make territory there. Corners and sides are much more efficient, because the edge does part of the surrounding.
Fix: corners first, then sides, then the centre. Go opening principles explains why.
8. Always answering locally
Beginners usually play right next to the opponent's last move. Sometimes the biggest move is somewhere else entirely.
Fix: once per move, lift your eyes and ask: "Where is the biggest point on the board?" If nothing urgent is happening locally, play there.
Mistakes at the end
9. Passing too early or too late
Passing while borders are open gives away points. Refusing to pass while playing pointless moves inside your own area wastes time (though with area scoring it costs nothing).
Fix: use the checklist in how a Go game ends: close borders, capture dead stones, resolve kos, then pass.
10. Leaving dead stones on the board
On this site, every stone on the board counts at the end. Beginners sometimes pass with a hopeless enemy stone still inside their territory.
Fix: capture it. In area scoring, playing inside your own area does not cost points.
How to work on these mistakes
Do not try to fix all ten at once. Pick one or two, play five games against the computer on the home page paying attention only to those, and then pick the next. When you play people on the online page and save your games on your account, replay your losses and label each disaster with the mistake number from this list. You will quickly see which two or three habits cost you the most.
A note on attitude
Go punishes greed and panic more than ignorance. Many of the mistakes above come from wanting to save everything or capture everything. Players who stay calm, accept small losses and keep their groups healthy improve fastest.
A worked example: the chased stone
Picture a black stone near the edge that White has put in atari. Black extends; White ataris again from the other side; Black extends again. After four or five moves Black has a line of stones with one or two liberties crawling toward the edge or into White's wall, and White has built a row of solid stones around it while giving nothing away. Eventually the black line is captured anyway, and White's surrounding stones now form strong territory.
Compare that with the alternative: after the first atari, Black simply plays a big move elsewhere, for example taking an open corner. White captures one stone — one point in area scoring — and Black has a whole new area. That trade is almost always good for Black.
The lesson is not "never save stones". It is: save stones when saving them gains something. A stone that connects two of your groups, or that is part of a group's eye space, is worth fighting for. A single stone that is running nowhere is not.
A worked example: the cutting point
Another very common story: Black has two groups linked by a diagonal. White pushes, cuts through the diagonal, and suddenly both black groups are weak and must run at the same time. White attacks one, builds strength, then turns on the other. Black loses one of them, sometimes both.
The fix costs one move early on: fill the cut before White can use it, when you can see that the separated pieces would be weak. If each piece is already strong and could live on its own, the cut does not matter, and the connecting move would be slow. Learning to tell these situations apart is one of the most valuable skills in the first year of Go.
Checklist for your next five games
Before each move, run through three quick questions:
- Is any of my groups in atari or down to two liberties?
- Can my opponent cut something important?
- Is there a bigger point elsewhere on the board?
It feels slow at first. After a week it becomes automatic, and most of the mistakes above disappear on their own.
Frequently asked questions
Which of these mistakes costs the most?
For most beginners, not noticing their own atari (mistake 2) and saving hopeless stones (mistake 1). Both lose whole groups.
Is it ever right to crawl on the second line?
Yes, when it saves an important group or when the wall the opponent builds is useless. As a default habit, it is slow.
How do I know which stones are hopeless?
Count liberties and escape routes. If the stones are running into a wall of enemy stones with few liberties, they are usually lost.
Should I play next to my opponent's last move?
Only if something urgent is happening there. Otherwise, look for the biggest point on the board.
Will I stop making these mistakes quickly?
Most players reduce them within a few weeks of regular small-board games, especially if they review their losses.
