Learning Go: From Your First Stone to 9 Dan

Go is one of the oldest games in the world, and also one of the simplest to learn and hardest to master. If chess is a battle, Go is building an empire.


The Basics in 2 Minutes


Go is played on a 19x19 board. Two players, Black and White, take turns placing stones.


3 rules you need to start:


1. Surround to capture. If you completely surround your opponent's stones (no empty adjacent points - called liberties), you capture them.

2. No suicide. You can't play a move that leaves your own stones with zero liberties, unless it captures opponent stones first.

3. Ko. You can't immediately repeat the board position.


That's it. You win by controlling more territory than your opponent. A 30-minute YouTube video and 2-3 games on a 9x9 board and you'll get it.


Steps to Actually Learn Go


Step 1: Start on 9x9, not 19x19

Forget the big board for now. The 9x9 board teaches life-and-death, capturing, and how games end. Play 20-30 games there. Apps like BadukPop, Go Quest, or http://online-go.com (OGS) are perfect.


Step 2: Learn the concepts, not just rules

- Atari: Putting stones in danger (1 liberty left)

- Ladders and Nets: How to actually capture

- Life and Death: When a group needs two eyes to live

- Shape: Good shape is efficient, bad shape wastes moves


Step 3: Do tsumego (puzzles) every day

5-10 minutes of life-and-death puzzles is worth more than an hour of random games. This is how every strong player trained.


Step 4: Play and review

Play 19x19 when 9x9 feels small. Lose. Then review. In Go, we say "Lose your first 100 games quickly." Use AI review on OGS or KaTrain - it will show you where you lost 5 points by playing a small move instead of a big one.


Step 5: Get a teacher

A club, a Discord, or a stronger player who will play teaching games. One comment from a 3 dan player is worth 10 self-played games.


So What is 1 Dan to 9 Dan?


Go has two ranking systems:


Kyu (student ranks) - 30 kyu to 1 kyu

You start around 25-30 kyu. As you get better, the number goes down. 30 kyu is a total beginner, 1 kyu is a very strong amateur, just one step below master.


Dan (master ranks) - 1 dan to 9 dan

This is where it flips. 1 dan is the first master rank. From there, higher is stronger.


There are two completely different kinds of Dan:


Amateur Dan: 1 dan to 7 dan (8 dan in Japan)

This is where 99.9% of us live. A 1 dan amateur is a solid club player who understands the whole board. A 4-5 dan amateur could beat 99% of people who have ever played. A 6-7 dan amateur is nationally strong - wins big tournaments.


Professional Dan: 1 dan to 9 dan

This is a job title. You only get it by passing the professional exam in China, Korea, Japan, or Taiwan. A pro 1 dan would crush most amateur 7 dans. Pro 9 dan is the highest title in Go - reserved for world champions and legends like Lee Sedol, Ke Jie, and Shin Jinseo.


A handy comparison:

Rank Who they are

15-10 kyu Learner, knows rules, makes big mistakes

9-4 kyu Regular club player, understands territory

1 kyu - 1 dan The big wall. Takes 1-2 years for most dedicated players.

Amateur 3-4 dan Strong local teacher level

Amateur 6-7 dan National amateur champion level

Pro 1 dan to Pro 9 dan Full-time professional. 9 dan is lifetime achievement + world titles

How Do You Get to 9 Dan?


Let's be honest: You almost certainly won't, and that's okay.


Path 1: Amateur 9 Dan doesn't really exist. The highest official amateur rank is 7 dan (or 8 dan in Japan as an honorary title). Even amateur 7 dan takes 10+ years of serious study for most people.


Path 2: Professional 9 Dan - The Real 9 Dan


1. Start young. In China and Korea, most pros turn pro between 12-16 years old. They've studied 8-10 hours a day since age 6.

2. Become a pro 1 dan. Pass the pro exam - in Korea, only 3-4 people pass per year out of hundreds of insei (pro trainees).

3.Climb by winning. In the past you were promoted by wins. Today, you get to 9 dan by winning major titles and accumulating prize money / promotion points. In Korea, you need to win a major international title or get enough career wins. In Japan, it's 40 years of service + achievements.

4. Stay there. Pro 9 dan isn't just strength, it's legacy. There are only about 150-200 active pro 9 dans in the world.


For a normal adult learner starting today, a realistic, amazing goal is:


30 kyu -> 15 kyu in 2 months -> 8 kyu in 6 months -> 1 kyu in 1-2 years -> 1 dan in 2-4 years -> 3-4 dan if you keep studying for 5+ years.


The secret? It's not talent. Every strong amateur did the same three things: played 2-3 serious games a week, did 15 minutes of puzzles daily, and reviewed every loss with someone stronger.
