[Diagram]
Diag.: The Small nadare

Black 1 starts the ko-nadare (small avalanche) joseki, after which the moves to Black 5 are all forced. White A next is usual, white B is possible if the ladder is good.


[Diagram]
Diag.: The basic variation

After white 1, black 2 is the most usual answer, but there are other variations. After white 3, the two black stones at the edge cannot be saved, so black goes for the upper side instead. White has some influence along the left side as well as points on the corner, but black's thickness on the right is truly impressive, he having captured two stones. Also note that black's influence is along the upper side, which is often more important than the left side if white chooses to play the NadareJoseki. This is by far the most common variation of the small nadare.

Note from John Fairbairn: This statement seems misleading, at least as regards professional play. In the GoGoD Nadare collection of 905 games, only 85 are small avalanches and of these only 20 show the above variation.

Is there a variation that occurs more than 20 times? If so, what is the most common variation? --BillSpight


[Diagram]
Diag.: White tenuki

There are cases where white omits white 9 in the previous diagram, but they are rare. A likely continuation when black pulls out with 1 is shown here. In this diagram black has played on both sides - the difference with the normal joseki is large.


[Diagram]
Diag.: Avoiding tenuki (9 connects)

If black wants to avoid the white tenuki, he can play at 4 here. Black is now guaranteed of sente, but his thickness is much less than in the basic joseki, so only rarely are there points elsewhere which are large enough to makes this worthwhile.



Dnerra: Here I started a useless discussion on the last diagram, which was abruptly stopped by unkx80's ingenious comment that Black just has to reverse the order of B6 and B8 in the last diagram :-) I moved the obsolete discussion to a separate page called Small Nadare Black Wants Sente and corrected the last diagram (assuming Andre consents). (If so, feel free to delete this paragraph.)

unkx80: I won't call it a "useless" discussion. :-)

Dnerra: :-) Well, I could have noticed the wrong order of moves in the original diagram myself before starting this discussion...


[Diagram]
Diag.: The vital point

Black 2 at the vital point is a strong move which provokes a fight. Upto white 9 there is little room for variation.


[Diagram]
Diag.: Preparing for a fight

The Joseki continues with these moves, but the fighting is just beginning. The black group in the center and the white one on the top will have to fight it out afterward. White may choose to give atari at A before playing 2. This will make white B sente, but the value of white C is diminished. Black D is a common follow-up, but requires a ladder.


[Diagram]
Diag.: A third possibility

Black 2 is a third possibility, and again leads to a fight in the center.


[Diagram]
Diag.: A third possibility

Again white can choose whether or not to give atari at A first, while black may choose to play B rather than 2. C, D and E are all possible continuations for white, after which the fighting spreads into the center.


[Diagram]
Diag.: A ladder

White 1 is the other possibility here, but it can only be played if the ladder in this diagram does not work for black.


[Diagram]
Diag.: Too submissive

If the ladder does work for black, the only way for white to avoid an immediate collapse is to extend at 3. However, black 4 now is enough to capture the corner, and black's advantage is immediately apparent.


[Diagram]
Diag.: Bad for black

On the other hand, if the ladder favors white, black 2 is wrong. Black has no good answer to white 3 - both sides capture two stones here, but the marked black stone has become completely worthless. This diagram means downright failure for black.


[Diagram]
Diag.: If the ladder is bad

If the ladder does favor white, black has no choice but to play black 2 here. With black 8, black has saved his corner, but still must face the center fight. The continuations are the same as above, with white having the advantage that white 1 makes better shape than white A would do.
