One Space Low Pincer Invasion Interception
Path: OneSpaceLowPincer · Prev: · Next: OneSpaceLowPincerInvasionBlock
If black intercepts at 1, the joseki to white 8 can be expected. After this, black has several choices. Among professionals, playing tenuki seems to be the most common. If white gets to play here next, A is the most likely spot.
With black 1, black extends his thickness. After this, white normally answer at 3. This may seem like a lukewarm move, but actually it is honte. Any other way of defending leaves too much aji for black to aim at. If white does not answer black 1, black will make the profitable exchange of black 3 for white 4. It is painful for white to allow black this exchange in sente, but still it is playable - the sequence here was played by Cho Chikun (black) against Kobayashi Koichi in the 1999 Kisei title match.
The pincer of black 1 is rarely played directly. Nevertheless, it is a common manoeuvre for black. After white 2 and black 3, white has sente, but black has confined her to the corner, and now has strength on both sides and the center.
The alternative for white is to run into the center with white 2 and 4. After white 10...
Black patches up his shape with black 1. The continuation to 8 is one possibility. White has set her eyes on the two black stones on the left, but black 7 makes him thick in the center.
Black 1 is not a good move with the 1-space low pincer. The marked stone is now too close to black's own wall.
Few variations are possible to the basic joseki after black 1. One possibility is for black to black 7 here rather than on A. The advantage is that white can now not play at 7 to either connect her stone or cut off black's wall from the rest of his position on the top, and that the hane-and-connection of white B is not sente in the yose. The disadvantage of course is the possibility of the white cut at A.
A second variation is black 3 here (rather than A). Compared to the basic joseki, black takes more territory and less thickness. If white 8 is omitted, black B causes her problems.
If white does want to take sente, she should play white 6 here. However, the difference in black's thickness between the previous diagram and this one is considerable.
Black 3 feels natural (hane at the head of two), but it is a mistake. There are two ways for white to punish it. The first is by the simple hane and connection of white 4 and 6, followed by the tesuji of white 8. If black draws back at 9, white connects at 10. Compared to the normal joseki, black has made the extra exchange of black 3 for white 10 - which is clearly aji keshi.
If black tries to resist with black 1, white cuts at 2. One possible follow-up is shown. If black does not play at 7 (but for example at 9), white wins the semeai after white 7-black A-white B.
Black has been forced into a clumsy shape, while the marked stone has been cut off. The four white stones are far from captured yet.
The second possible answer to black 1 is white 2. If black connects at 4, white connects underneath at 3 and is satisfied with her corner area. However, if black descends to 3, white fearlessly cuts at 4. If black tries to save his stone on the left with 5, white goes after the three stones with 6.
White 4 is the tesuji. After this move, the four black stones have no possibility left for escape.
