## 13×13 Go

Standard Go rules on a 13×13 grid. The intermediate board bridges the tactical intensity of 9×9 with the strategic depth of 19×19. Games typically last 30–60 minutes. Used in some official tournament categories and widely played online.

### Setup

Same as standard Go. Board starts empty. Black plays first. Komi: 5.5 points for White.

### Rules

All standard Go rules apply without modification. Placement, liberties, capture, ko, and suicide rules are identical.

### Differences from 19×19

- Fewer intersections (169 vs 361) means influence radiates further relative to board size.
- Opening theory is less developed, encouraging creative play.
- Corners and sides are proportionally larger relative to the centre.
- Games are decided more by fighting and reading than by large-scale framework building.
