Shimari

Shimari refers to a formation where two stones are placed in the same corner to create a secure enclosure.

The term shimari comes from Japanese and means “tightening” or “closing,” capturing the idea of securing the corner area. In English, it is often called a “corner enclosure.”

A shimari is a simple and effective way to defend the corner in Go. By placing two stones in the same corner, you secure the area and make it harder for your opponent to invade or reduce your territory. Corner enclosure also creates a good base for extending along the sides or building influence toward the center. There are different types of corner enclosures, each offering its own advantages depending on your overall plan. Knowing common shapes and the joseki sequences that go with them can help you play confidently in the opening.
