Black presses at seeking to control the balance of the whole board. But after White makes the diagonal play of , White has all the points. So lacking any special situation, Black can not use this diagram.
No other diagram is given for Black's response to .
tderz: it is important to think about protection vs. the cut a-b-c, e.g. with a move at d.
dnerra: I think the usual continuation is the following (I am not quite sure here, though):
In this joseki, Black can play the large endgame move at in sente (of course, "sente" here should take the temperature into account).
In this joseki, Black can create a ko with and , aiming at either a or b.
However, it seems that people nowadays prefer to play the first joseki.
tderz An honest question: are professionals really play Joseki 1, and more often than variant 2?
unkx80: I shall try to give a very quick answer before I go out for dinner.
A honest answer: I have not been studying professional games, so I don't know. One thing I always forget to do is to quantify my statements. When I say that "it seems that people nowadays prefer to play the first joseki", I base it on my perception from the very limited number of games I see and play.
tderz Hello unkx80! Long time no see.
unkx80: Hi! =)
In Joseki variant 1, Black also has the ko aji --! If the endgame exchange a-b has not taken place, the cutting points c, d exist.
tderz If, in Joseki 2, White connects safely at ,
Black only could achieve something, if there was a Black stone at a. However, and here comes my conclusion as absolute 'non-Joseki-expert', Black wouldn't have found the time in sente to play there!
That's why I would prefer Joseki 2 over Joseki 1.
tderz: If Black was moving to here its sente (threatening the ko aji), but rather slow. might be worth more.
unkx80: Here, I agree.
unkx80: I believe this also a joseki:
AJP: All about joseki says the above diagram is not joseki and that is bad for white after black extends to a rather than . They suggest this instead, in the context of white already having a position in the bottom left.
How should the Black handle the circled stone at this point? I felt that the result of the joseki favored White given Black's high stones and the right face a White position rather than a Black one, as might have happened if White had played at a .
mAsterdam: Could you please explain? (And check the colors? I assume you meant to ask how White should handle the circled stone. I circled it as there was no circled stone. Please remove this comment after editing).
Dieter: I think White may be happy to split Black this way.
