Can someone explain how to tell where I should throw in/when to throw in? I hear players talk about it all the time, and I always have a hard time understanding when I should go for it in my games. |

Throw in to - eliminate an eye if thereby the group is then not alive, - connect the throw-in string if it wins the capturing race, - accelerate reduction of approach liberties in a capturing race, - create a liberty shortage, - connect strings making them strong (thick), - prepare a squeeze, - prepare a semedori, - threaten to do some of the above if the opponent's reply cannot defend against all threats because of multiple threats or ko, - etc. EDIT |

Well, what are you trying to do? A throw-in is often used to make a false eye, so if there's a group you are killing and you read the throw-in kills it then play it. Or they can be used to reduce liberties (e.g. on first line), so if you read the throw-in reduces their liberties and lets you capture some stones you want to capture then do it. A snapback is another example of a throw-in tactic taking away liberties and often come up as a tesuji to capture some cutting stones. I wouldn't approach a game as "today I will make 5 throw-ins", but if you post a game of yours for review I can probably find some opportunities for throw-ins as they are a fairly common technique. |

Most good tsumego series for beginners will drill you on the throw-in technique by covering many, many typical situations. If you want to develop your intuition for it I would recommend the Level Up & Jump Level Up! series. |

The sequence to kill the J group is a good example of using a throw-in to eliminate eye space. In the second diagram in the following webpage, move 7 is the throw-in. Site: http://senseis.xmp.net/?JGroup Here are a few other examples of throw-ins: http://senseis.xmp.net/?ThrowIn |

Basically, it's sacrificing a stone inside your opponent's group to try and either kill it (usually), or make profit out of it that's greater than the sacrifice value. |

Throwing in happens in joseki, too. Here's a familiar one: WHite 10 throws in to the left of W1 in the second diagram to set up a squeeze. |

Here is an example of the throw-in to take away a potential eye and kill a group. White threatens to capture the  stone and make a second eye. After   at1 takes away that eye.Here is a throw-in to reduce liberties and capture stones. One to remember, called the Cranes’ Nest.  Edit: Also, here is a throw-in in a strange corner sequence. White has horrible shape.
