Answers To The Hane Discussion
This page is fired off by the BasicInstinct page, in which the statement Answer the hane with an extension was criticized. 1. Answering the hane with an extension ?
Reasons:
Exceptions:
2. Rather HaneKaeshi or CrossCutOf course, the surrounding conditions make a big difference, but in general I think that the extension is not so good. It gives the opponent the opportunity to make good shape.
If Black continues with B 3, the shape is the same as if Black had played hane at the head of 2 stones. (See BasicInstinct 4.) The first think I think about is a CrossCut. True, that give the opponent a chance to extend. (See BasicInstinct 3.) However, that is not so bad. You were cut, anyway. :-) But perhaps the counter-hane should be the first thing to think about.
The most tempting response is to play atari-atari, but then Black has to protect his weakness with B 5. Now W 6 captures the Black stone in geta.
B 1 can atari with sente, but then Black has two cutting points at a and b to worry about.
If Black protects, White can do the same.
If Black extends, White can play kikashi with W 2 - B 3, and then protect with the hanging connection of W 4. White treats the marked stone lightly.
When the marked stone is present, the nobi is a good response.
One of the reasons is that if Black plays at A, he reduces his own liberties.
