3-3 Point Invasion which peeps at the tiger's mouth
![[Diagram]](../../diagrams/36/6b60df70ef1abb169aba3ab7fb715e91.png)
The opening
is usually played to keep sente. Sooner or later White plays
, which is usually gote but which has a large follow-up.

The invasion
[1] Black can connect at a or resist? at b.
Charles In a small sample (3) the pro always connects.
Connection

Connection & block
Black can also cut White off with
instead of
, but then White can live.

Connection & cut
If the top right is big, Black plays this way. White lives

Variation
Taking the corner is usually too painful.
Resistance

Resistance
The question is whether Black can resist.

Refutation
This way, White wins by one liberty.

Refutation
would be a mistake I think. White loses a liberty.
Requires more analysis. --Dieter

Refutation?
iopq: Black wins the semeai? I think I'm missing something...

Refutation?

Building up liberties
JoelR: I think if Black tries to increase his liberty count with
or a, White can do so more effectively with
. If instead Black blocks at b, then White
.

Refutation
Herman Hiddema: White 2 in the previous diagram does not build liberties. If black plays like this white will never get more than three liberties. If white plays a, black pushes through and gives atari, then jumps again, creating a situation similar to this diagram. So white can only play like this if he can link up with some stones of his own by playing a.

Crawl OK
Bill: If
, the crawl at
suffices. Black's attempts to smother White with
-
fail.
tderz: Maybe these are the reasons that/(if) the white clamp b in [1] is safer for black (life or connection) instead of cut-and-capture or connection (
in [1])?
