Connect instead of hane

    Keywords: Shape, Tactics

This page is in need of attention.

Sometimes, one has to counter one's basic instinct and connect instead of hane.


This double keima-like shape is often seen, not only on the second and third lines.

When White plays W1, your basic instinct (hane against tsuke) may compel you to play a, making a tiger shape.


However, connecting with B2 is generally better. Now Black can either take profit at a or c or jump to b. If instead ...


... he hanes, the atari W3 forces an answer. After W5 - B6, Black is forced into a low position.

Incidentally, B6 is a keima connection, and another example of technique. For comparison, ...


If Black connects first, he will play B4 rather than a (next diagram):


B4 and B6 are submissive.

This is an example of tewari: the inversion of move order shows us something is wrong with the hane in the third diagram.

Disputing tewari and some questions

tapir: I don't particularly like this tewari example because while it claims that Black made two less than optimal moves, White made just as much. Look in the tewari diagram at W3, it is a wasted move - making an empty triangle in gote, W5 next forces Black to live in the corner, but leaves a cutting point behind. Also I ask myself, is B6 not better played as atari? (Then the corner is safe already, also White can not close the side in sente as with this forward played B6.)

If the hane is wrong, is this better? (Changed from the submissive diagram)  

unkx80: I don't know how to assess this position. I would like to have white though. But note that black+circle already makes black low in the first place.

tapir: Me too. This diagram should expose the argument in the tewari above. It gives W3 and concludes that would be bad for White now, since Black would play at B4 and not the hane now. It is not a sequence that will happen in any game though.

What I know as joseki (notice the B stone)  

unkx80: I agree with this B6. It is better than a.

Isn't White better here than in the above diagram?  

In the situation given above there is no black+circle, but then White is strong and will get an extension while Black is very low on the side, but maybe living when you tenukied on the approach is good enough.

Let us look at B6.

After B6 - I  

White follow up if the side is big (while technically gote, white capturing next is huge and likely sente - otherwise White can shut in Black in sente with a move like a). If Black the corner is 10 points - in gote, compare this to a standard 3-3 invasion, which is about as big, but ends in sente.

After B6 - II  

Here B8 is pretty much forced (otherwise White takes the corner in sente by playing at 2-2 next). However, if we change the sequence and play the atari at B8 instead of B6, then it is not clear that we really want to answer W7 by playing B6.
