3-4 point high approach, two-space high pincer, keima

    Keywords: Joseki

This move will be answered by Black's cut at a, regardless of any ladder. Actually, Ishida may say this is bad for White - but that's old information.

Forced cutting sequence  

1. White stretches aggressively

Stretch 1  

When White aggressively stretches with W1, Black can stretch too at B2 or play a (see later).

One continuation  

After Black's outside attachment, White will eventually have to live on the side, while Black takes central influence. Next Black can aim at attacking White's other group. This fight has been regarded as favourable for Black in most circumstances, a.o. by Ishida's Joseki dictionary.

Stretch 2  

Each of Black's moves B2, B4 and B6 are sente and cannot be answered by a hane: each cut will be favourable for Black. In the end, White cannot even play W9 at B10, so Black takes a big corner. All the cannots'' in the above explanation can be explored further.

2. White stretches into the other direction

New joseki  

This variation has been played for 20 years, and is popular right now in pro games. B2 is a common tesuji.

Common continuation  

Up to W5 is a common continuation in recent pro games. W1 and W3 can be played in a different order. (17 games out of 47 in a gobase search on this position) Most variations are about B4: it is seen at a, b', c and d. W5 is seen at a and z.

Another continuation better for black  
Another continuation better for black  

White is now dead

Why 2 is tesuji  

If White pushes at W3 and W5, Black happily connects. White will not be able to save his top stones.

The resembling move  

This is not tesuji. Black is split into three groups.

3. White peacefully plays atari (not recommended)


This peaceful result can easily be visualized. Black takes a substantial amount of territory. White takes influence and sente. However, it is felt that white+circle is not placed effectively. In fact, there is a joseki resulting from the ogeima variation where white+circle is instead at a. That result is considered even and the final judgment will depend on whole board strategy or personal preference.

4. Other moves

Alternatives 1  

There are a few games in which Black fiercely plays B2. After B6, White can retreat at a or fight at b. These fights then spread over the whole board.

Alternatives 2  

There are also a few games where B2-W3 is exchanged, resolving into the main variation again. That leads to the question why B2 at a is tesuji at all.
