A throw-in is a sacrifice play in which at least one stone is captured by the opponent, played in order to destroy eye shape or reduce liberties.


A throw-in is different from a nakade. A nakade is a play inside a real eye. A throw-in makes or maintains a false eye.


[Diagram]
Throw-in

White 1, trying to squeeze one extra point out of Black is a mistake. Black can throw in at 2, and the eye here is false. Even if White takes at a, Black does not have to respond, as the eye at 2 will never become real. White 1 at 2 would have lived.

Throw-in (4 at 1)

In this example, a throw-in is used to remove the eye which White could have made here. A throw-in is often the first move in a snap back, damezumari, oi otoshi sequence, or a squeeze tesuji.

--MortenPahle (10kyu)



A very common and useful technique is the Throw In Under Three. --Dieter

Another commonly application of the throw-in tesuji to destroy eyes can be found at Beginner Exercise 4. --unkx80
