Shortage of liberties

Shortage of liberties (damezumari in Japanese) causes many of the basic tactics of the game..

[Diagram]
Shortage of liberties: seki

In this diagram, a seki is created: Black cannot approach White at the circled intersection because he already is short of liberties - by approaching he would fill one more of his own liberties and White could at the square-maked point). Note that if Black's eye was larger, he could capture the two white stones.


[Diagram]
Shortage of liberties: oi otoshi

Here is an example where the three marked white stones are in damezumari. When Black plays at B1, White cannot respond at W2, but must answer at W4 or B5. White must give up the three stones.

This diagram is an example of oiotoshi.



Making your opponent connect is not really putting him in damezumari

During the comments on a game between two beginners, it happens that thay seems to misunderstand damezumari. I'll write down the dialogue and the diagrams as I can remember it.
If I'm wrong, please let me know.

Damezumari

Black player : Here dkiller, this is a good move, I'm playing a damezumari. Dkiller : How can you say that a damezumari is a good move? Black player : How it can be wrong? Before White had three liberties, now she has only two liberties, It is a good move. Dkiller : Oh my god, we're not taking about the same 'damezumari'; see the continuation.

Damezumari

Dkiller : You see, now White is connected, she has 8 liberties. It's a lot more than the three liberties he had at the beginning. In the other hand, Black has only two liberties and before she had three liberties. With the cut at a, it is very worrying to have so few liberties. That's why I said it was a bad move.
To conclude this exchange I would say that you can't really put your opponent in damezumari, you can only put yourself in damezumari (often a bad move) or use already-present damezumari to solve in a particular way a local situation.

Damezumari (really)

Charles Matthews The correct way for Black to play here must be B1 in this diagram, which is worth a point and threatens a snapback.

Bill: And if then W2, B3 protects against the cut at a.
