Life, Death, and Eyes
Understand why some groups can never be captured and others are in trouble.
Beginner lesson. Board: 9x9. Estimated time: 9 minutes. Concepts: eyes, false eyes, surrounding.
Reference notes
- A living group can make two separate real eyes.
- A false eye can collapse because the opponent can capture the eye's support.
- Surrounding a group matters more than chasing it one stone at a time.
Practice prompt
Pick one weak group and spend three moves trying to make it safe.
Review check
After scoring, check whether each dead group had no real two-eye route.
