Tengen: The Center Point
Tengen is the exact center of the Go board — the 10-10 point on a 19×19, marked with a star. Because the center is the hardest place to make territory, opening on tengen is rare and bold, a statement that you intend to play a game about influence and fighting rather than quiet corners.

What tengen is
Tengen simply means the central star point of the board. On a 19×19 it's the 10-10 intersection; smaller boards have their own center points too. It's marked like the other star points, but it sits alone in the middle, far from every edge that helps make territory.
Why opening on tengen is unusual
The opening usually goes to the corners, where territory is cheapest, so a first move on tengen breaks convention. It makes almost no immediate territory. Instead, it aims at central influence and whole-board fighting, hoping the central stone will help every battle that develops. It's famous from a few historic games but rare in ordinary play.
When the center matters
Even if you don't open there, the center grows in value as the board fills and frameworks push toward the middle. A stone near tengen can cap an opponent's moyo, support an invasion, or link fighting groups. So while tengen is a poor place to start, the center it sits in often becomes decisive later in the game.
Frequently asked questions
- What is tengen in Go?
- Tengen is the center point of the board — the 10-10 star point on a 19×19 grid. It sits farthest from every edge, which makes it a place of influence rather than easy territory.
- Should I open on tengen?
- Usually no. The corners make territory far more efficiently, so opening on tengen is a rare, influence-oriented choice. It's a bold strategy famous from a few historic games, not a standard opening.
- Why is the center hard to make territory in?
- Because no edges help you surround it. Enclosing central space takes many more stones than a corner, where two edges do much of the work. That's why openings favor corners and why tengen is about influence.
