Clamp

When a friendly stone is already next to an enemy stone, a clamp is an attachment on the opposite side of that enemy stone.

Clamps can occur anywhere on the board at any stage of the game, as shown in the following examples.

The Japanese term for clamp, ハサミツケ　 (hasami-tsuke), means literally "pincer attachment".

As can be seen in the example, the second line clamp is a common end-game tesuji. It makes a and b miai.

Types of clamps:

• Endgame Clamp
• The Cut-Threat Clamp
• Belly attachment
