Yes, like we discussed having your stones die in a killable eye shape is a key way of killing groups.

Have I read this correctly? The only way for black to capture is to play at 1. If white plays in the corner, black gets captured but can then play at 1 again and white cannot create two eyes. W will run out of liberties before black, so black gets the whole W group. Yay or Nay? |

I wouldn't call it a sacrifice, but yeah. |

http://senseis.xmp.net/?Nakade is perhaps a term that may be used, though I usually don't really use a specific term but just say that "1 here kills". I generally use sacrifice as a macro/strategic concept. A similar tactical idea to allow the opponent to capture in order to remove eyes is http://senseis.xmp.net/?ThrowIn |

It's not a sacrifice because white won't (shouldn't) capture, except as a ko threat. |

Yes, like others have said, sacrifice is mostly used for a situation where there is some kind of trade: I give up a few stones and my opponent gains something from it, but I get something in return. Here, Black loses nothing. |
