In this post, we are going to discuss the variations of the two-space low pincer in the orthodox opening.
White has three possible responses. Tenuki is not good because black can kick the white stone and then jump. The pincer stone is in the perfect place to attack.
If white goes to the corner, black can be satisfied with the result because black is not as over-concentrated as the variation with the one-space low pincer (see Orthodox Opening I).
So, white has to choose a double approach. Let’s look at the low approach first.
There are josekis for A, B and C.
This variation is considered good for black because black is very thick, the exchange of white 3 and black 4 is good for black., and M17 is sente for black.
If white extends instead of going to the corner
Difficult fight for white. Black is already alive in the corner so it’s only white who is being attacked.
Trying to counter-attack is a bad idea because black has support in the lower right corner. White will have to take care of two weak groups.
Another variation: black is developing the lower right corner.
This attachment is another joseki. Black needs to be careful not to play the wedge at A.
This result is good for white. The marked stone is in a bad position as it can’t help seal white in.
Good for black. White is still not alive on both sides.
Another variation: Black 10 is a strong move. White’s four stones are in big trouble.
Black is very thick in this variation and white can’t really attack the pincer stone severely.
