Introduction

A squeeze (or squeeze tesuji) is a play or sequence that forces a player's stones into an inefficient shape by wringing out the liberties of a group through combination of sacrifice and forced capture? exchanges. Beneficial exchanges, leading to the squeeze, can be forced by ataris and atari/capturing race threats.

Squeeze plays are very rewarding and can range from easy to spot to highly sophisticated. Nonetheless, with a bit of practice you too can see how to set up squeezes and force your opponents into inefficient shape, and conversely, avoid being squeezed yourself.

Example 1

Squeeze tesuji  

In this example, after White plays W1, Black invites the cut with B2, sacrifices B4 ...

... in order to force with B6 and then squeeze with B8 and B10 - ending up with good shape and leaving White in a dango shape.

[Diagram]
Continuing pressure  

Black continues to squeeze White, making territory in the process.

Final position  

White's group is still weak.


Example 2

[Diagram]
Lethal squeeze (White 4 connects)  

The squeeze can also be used as a capturing technique. In this example, Black sacrifices the marked stone to squeeze with B1 and B3 and subsequently kills with B5.


Example 3

[Diagram]
Black can't resist  

Before connecting, White pushed a little bit into the center with W1. Black could not resist B2. Instead of trying to save the marked stone, White plays W3.

[Diagram]
White solves a larger problem  

Followed by W5, which seals the black group in.

[Diagram]
Black is dead  

B6 leaves Black with a very bad shape, and White plays out to W7, guarding against a cut at a, and sealing off Black's escape route through b.
