Corners, Then Sides, Then Center
Path: GeneralOpeningPrinciples   · Prev:   · Next: ShutIn
  Difficulty: Beginner   Keywords: Opening, Proverb

This phrase is one of the first things a Go player is taught.

  • It is easiest to make life in the corners, then the sides, and least easily in the center.
  • It takes only two walls of stones to surround territory in the corners, and three on the sides, compared to four in the center.
