![[Diagram]](../../diagrams/46/49102034e622df4ccd32a2ce8d0d1ab1.png) | 4473 enclosure |
This is a common way to develop a 4-4 point in the corner.
![[Diagram]](../../diagrams/35/81d28f549be6fe5a73690912196d10c6.png) | The 3-3 invasion |
This is the main variation of White's 3-3 invasion of the enclosure. may also be played at (see below).
For at see 4473 enclosure 3-3 invasion, block on inner side.
![[Diagram]](../../diagrams/29/99c4016bd736d424b08b890f7c19a795.png) | Main variation, continued |
This is the standard line, and White ends in sente. The White group is an L+2-group and is alive. Black though has considerable influence now.
Variants:
-
at a, challenging to a ko.
-
at b. This affects forcing moves (Black d is then sente against the corner), and endgame plays in the corner. With as played, Black c threatens a ko in the corner.
- Black on occasion omits
net example 5, but then White at causes a fight.

Black may also play this way. Then (or a) lives. here is proper, but may be omitted: if Black wants to end in sente here it may make sense to play in this manner, rather than follow the above main variation.
Dieter: Question. at a reduces the corner to an L+1-group, whose status depends on sente. So Black can play a in sente ?
![[Diagram]](../../diagrams/32/2732ed5d9f0b6c044f14f24e7f1069c8.png) | Kikashi |
Here is certainly a good kikashi against the corner. And here is a useful way to follow it up, for fighting purposes, since it still threatens the corner. It is unlikely to be the correct endgame play, though, in typical situations.
Chtito: I have a question about an approaching sequence that I don't understand:
![[Diagram]](../../diagrams/26/eeeb48ed3df43a2b23a0cf73564af734.png) | Corner Sequence |
After , the sequence White a, Black b is played. Now my question is: why White does not play b instead of a? How would Black punish a white play at b?
![[Diagram]](../../diagrams/0/a7d6748ebfcea6a6d17f5e57d0c1f1aa.png) | Can White play this? |
Charles Well, if and it becomes very dangerous for White. After can White cut at the marked point? I don't believe so. In any case White was strong here first, so that White shouldn't have to fight in such a desperate way: it should be Black's problem to find good moves, and here it is White's.
at is quite bad, while at is possible but not really interesting.
