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

[Diagram]
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 (W4 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.
