3-3 Point Invasion which peeps at the tiger's mouth
is usually played to keep sente. Sooner or later White plays
, which is usually gote but which has a large follow-up.
[1] Black can connect at a or resist? at b.
Charles In a small sample (3) the pro always connects.
Connection
Black can also cut White off with instead of
, but then White can live.
If the top right is big, Black plays this way. White lives
Taking the corner is usually too painful.
Resistance
The question is whether Black can resist.
This way, White wins by one liberty.
would be a mistake I think. White loses a liberty.
Requires more analysis. --Dieter
iopq: Black wins the semeai? I think I'm missing something...
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
.
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.
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])?
