O to play

* * * * * * * *

* * b a * * * *
* * 7 X * * * *
* * 1 2 6 O * *

Now X is supposed to play 8 at a.
But in a recent game, my opponent cut at b:

* * * * * * * *
* * X * * * * *
* * * * * * * *
* c 8 9 * * * *
* * O X * * * *
* * O X X O * *
* * O O X * * *
* * * * * * * *

So I cut at 9, he played c,
and I got a bad result (of course).

What's the best play after X plays 8?

I hate people who don't play joseki.

In more conventional diagram style:

| . . . . . . . . O to play.
| . . X . . . . .
| . . . . . . . .
| . . b a . . . .
| . . 7 X . . . .

| . . 5 3 4 . . .
| . . . . . . . .

Joseki doesn't work like that. If you think of joseki as what the player
is “supposed to do”, you'll always be vulnerable to players who don't.

Following joseki is a *weakness* unless you already know, in *this
specific game*, how you will punish an opponent who deviates from it.

What was the bad result?

> I hate people who don't play joseki.

That's a bit irrational. If you feel that way, perhaps you should not
follow joseki and instead remain flexible to whatever your opponent
does?

Your move 7 was not joseki.
If you want to play 7, do it before the hane-tsugi.

This pattern is discussed in both Yoshida and Kogo.

It absolutely is joseki.
The question is how to punish X,
after he plays 8.

Given the hane with 3, 7 is NOT joseki.

You can follow Kogo's developments further, if you're interested.

Sorry, I'm human, not a robot, I don't talk binary.

Anyway, the line you reference is a different
move for 7. The variation I posted is
certainly a joseki, if not THE joseki. You
can find it in Cho's or J. Davies' books.
X's 8 deviates.

I'm done with this "yes it is",
"no it isn't" inanity.

SGF isn't binary, it's an open text format for go and other games.
Admittedly not text designed for a human to read directly, but then the
same is true for HTML.

You can take the text of the SGF document and feed it to any of a number
of Go game viewers; “Quarry” <URL:http://home.gna.org/quarry/> is one
I like but you likely have used others and maybe have already chosen
one.

I believe you're thinking of the joseki where X plays a
tight pincer instead of making the shimari.

I dunno, that looks weak, like bowing
to X... if that's true, then 8 becomes a
good play, why is 9 the joseki? (insetad of 8)
