This is a personal reference page. Please don't edit it. In fact, you probably shouldn't read it, since it mostly contains my observations. I'm not all that good. I wouldn't want my mistaken opinions poisoning your Go.
I rarely play on the 3-3 point as an initial move. Supposedly, you can use these joseki on all shoulder-hits to third line stones, I've been fussing around with that a little lately, and I'm not sure how they really work out.
This works well for building one-sided walls when used out in the middle of the board. 'a' is especially big near the corner. White can play at 'b' to prevent this in gote.
This variation builds a wall that creeps into black's territory. According to the book, anticipates using 'a' to wall off the side, so is usually played at 'b'. This would be really interesting where 'c' is reletively unimportant (Black uses a shoulder-hit to try and keep White low).
I'm interested in responding to kakari on the 3-4 Point since I 'm starting to work with the Chinese Fuseki. I really need to learn how to respond to the high-approach well, but that's mostly for squeeze plays.
Play at a threatens continuation at b. Play at c can threaten continuation at d. is essential to prevent getting sealed in.
I like the way this variation seems to work with the Low Chinese Fuseki. I included the version with the double-hane, since I want to study this one more. To keep it simple, I can just play at and extend out toward the center. I need to work out how respond if my opponent doesn't play the Joseki the right way.
The pincer is probably the best way to respond to the high approach. I figure the one-space pincer is the most severe, so it probably will lead to the most fighting. Since fighting is what my new Fuseki is kind of about, it makes sense.
White has continuations at 'c' and 'd' (counter-pincer). The variations get complex at this point. I imagine I'd prefer 'c' to the counter-pincer, although I really have to examine this in a full-board context.
This variation abandons the pincer stone in order to get the corner and leave the option open for development on the left side. Not bad, but it relies on White being cooperative. I'm not sure that can be saved at all, but it looks like it might still be posible to attack White. Especially if there's a friendly corner enclosure on the far side. While this works really well toward establishing a moyo on the right if white has a shimari there, Black seems to actually have scope toward the center. Black at a, for example, would allow him to push out along the side with much profit. Since White already has stones in the area, responding by stretching--while it makes sense--would make him over concentrated.
This variation allows black to take territory and sente, but White settles herself. On the other hand, the absence of a white star-point stone on the upper side would make an excellent move all around (also prevents a counter-pincer). While third-line territory isn't ideal, the option to turn near allows this sequence to work well with the Chinese Fuseki, I think.
Moves out between the kakari and without really strengthening either group. While both groups will have to run into the center, continued attack of White's Kakari should yeild profit along the side. Question: Does black need to play at 'a' to prevent white from crossing under?
Basically, these versions seem to allow for a good deal of white complication due to the proximity of the stones. White 'd' from the first diagram especially settles her stones very quickly. I'm not sure I like the joseki along that line at all.
Usually, this sequence continues with wall building. White takes the lower side, and black faces the center. This variation is probably ultra-severe when black already has a stone at 'a'. Worth looking into.
White has good moves at 'a', 'b', 'c'. This is super-inefficient if the third stone of the Low Chinese Fuseki is present. It might preclude White at 'a', but I'm not sure. Black at 'c' might also be useful at a later point.
This sequence most likely will not occur in the situations I'm playing. I Imagine that the result will be too good for me, especially if Black can extend along the lower side and then press down from above. Watch out for a counterattack on .
This is the most commonly known joseki. I really should closely examine the follow-up moves at a and b. More importantly, I'm intested in how I can exploit devations from the joseki to really punish White.
Both the for and for exchanges are profitable for Black when compared to White at . If White plays at 'a' intead of , Black can play at 'b'. There is a complicated sequence in Diagram 6 of 38 Basic Joseki if White doesn't respond to .
This sequence seals white in. The idea here is to invite invasion of the corner and use it to build outside influence. The kakari (marked) has been sacrificed. Black gained some territory on the outside (White can probably still invade the 'extension' with the help of ).
This is another (better?) way for Black to respond to White's corner invasion. If is in place, Black can get a wall facing the right and make full use of the stone. and help seal off the left side, but White can get into the upper side with a.
Here, Black plays the pincer sequence in order to gain influence. The presence of the marked stone, , prevents white from flattening out along the top. The result is the much lighter play with and . Black can prevent White from fleeing by playing at a, but this variation gets complicated quickly (see 38 Basic Joseki pp 159).
Black Doesn't play the kite and makes his extension first. White invades with . With in place, the result seems far too good for Black. Black gets Sente and a wall on the left side. Not bad. Playing at a will create a sizable moyo.
I'm throwing this in to look at the difference between the high response and the standard low-chinese forcing play (which seems to match the handicap joseki).
This is the 'reccomended sequence'. creates a moyo above the white group under attack. I'm not convinced anyone who wasn't confident he was much stronger than me would play .
The attack on in the other diagram is much more stylish. can run out into the center quite quickly. What's more, white seems to be already settled. While is secured by the presence of , I can't help but think it's very inefficent. It seems like at 'b' would be better (but obviously wouldn't get the same result). Also, black's development will be stunted if white already has stones at 'a'. White at 'd' most likely won't happen against better players, but if it does, I'll take 4th line territory. Thought: If was not present when the kakari was made, would at 'c' be reasonable? I think maybe.
Strange. at 'a' starts a leaning attack. The problem is, this looks really violent. However, with reasonable fighting strength, could be isolated and attacked with much profit. This might be fun to mess with.
It does look like helps. White at 'a' can probably be answered near 'd', making a black play at 'b' better than C, I think. If white tries to use the corner to get eyes, Black can seal her in. Like the less severe response, white has scope to the center. I'm not sure it concerns black, though, unless White has stones that limit Black's development on the bottom (since 'd' creates a moyo on the right side).
As mentioned in the Second Book of Go, must be present for this to work, since otherwise, White can make an adequate extension. Black follow-ups are at a, b, and c. To me, c seems the most tame. It doesn't really put extra pressure on white, since White c can be answered at d. Of the two remaining options, b seems to accomplish the least. While it prevents White at e, I feel that black can answer at f in response--although e makes either g pretty big for White.
That leaves a as the most probable location for . First, White e is the widest possible extension here, black can respond easily if white tries to play in that direction. Secondly, a secures territory. Third, the one-point jump follow-up seals White in rather nicely. Black answering this way needs to watch for a counterattack on . If a looks slow, h operates in the same vein. Black can always play a in response to white's extension into the center.
Because of the size of the corner, black can probably afford to play instead of pushing again at a. While white can take this point, Black can just calmly descend making a White invasion at less feasable. also reduces the danger of immediate counterattack, as descending in response to at robs White of her base. White will probably tenuki at this point, since playing a might invite an unprofitable exchange.
