Did he, per chance, post the variation along with it? I can't be satisfied until I see it for myself.

It is past midnight here. I'll dig up my copy tomorrow.

BTW, welcome back to the world of go players.

I am fairly certain that if it's Black to play and he plays first here, there is no way for White to live unconditionally. I would be delighted to see a refutation though as I couldn't find any after quite some thought. Instead of posting 8,318 different variations that seem to work, I'll just wait for variations from others that show White can live unconditionally and try to debunk those.

I never claimed Black kills, simply that White cannot live unconditionally. Thus, seki and (desperate) kos count. The continuation I had in mind was:

Sorry, I expressed my self poorly. When I said "kills" I meant "prohibits white from living unconditionally".

So: how does this continue?

Araban, seki == unconditional life! Continuing from your previous diagramme, I don't see how black can make ko or kill. Unless I'm missing something, white lives in seki, and if this is the only thing black can do, the status of the original group would be "alive as it stands".

In fact, I wonder which is better endgame for black: making this seki or forcing white to live small by playing the hane/connect in the original position.
My name is Gijs, from Utrecht, NL.

When in doubt, play the most aggressive move

I thought seki counts as living unconditionally? To exclude seki I would think you need to say "white lives with territory".

I think it is a good shape for the Corner shapes page.

I always intended that page as a collection of different corner shapes that are just not territory. :grumpy:

and this is a rather simple ahape ( no cutting points or so)
and also it is one of the biggest shapes that is still not territory.


How about a page uncommon corner shapes? (I took the corner shapes to mean common corner shapes, it seems.) :geek:

Reasoning:
I still remember a certain 19k on IGS, when we played it was one of my first ten games there. Encouraged by his win, he gave me a long lecture after the game about the power of the sanrensei opening and other book knowledge. I fear that people may be inclined to learn the outcomes of the staircase ten as if they were as important as understanding the tripod group. As we see from Herman being 4 dan, the staircase ten isn't so important after all. :D Simply adding a phrase to that end, will do the trick I guess.

At the moment CornerShapes consist of "only" 33 different corner shapes on the page.

And they are all (i think) easely accessable from the table of contents.
(the page is nothing more than a list of diagrams (one per shape) a bit of text and a link to a more specialized page)

It was always my intention to also to include positions that were bordering between "alive with territory" and "alive in seki" . (because that was a detail that I missed in other books)


(And so that readers of sensei's have sometimes the joy of turning an "alive with territory" corner into an "alive in seki" corner ) :o :cool:

If you really like you can make a page of common corner shapes and if you like i can give you a hand (It is not that difficult just copy and paste the whole page, remove the uncommen shapes, and that is it)
I think the biggest problem is deciding what is common and not and maybe finding pages that you want to link your new page )

Hmm, yeah I don't know why I was thinking seki shouldn't count as unconditional life for W :scratch:. In that case, the situation is much different. I guess there's something unsatisfying about a group that lives without points.

So where do you stop listing? There are literally thousands of "corner shapes", e.g:

I would not list any of them

But that is mostly because in the first example White is dead and better abandoned (as far as i can see)

The second I would not list it because there is already a white stone inside Blacks area.

Also Black is alive (with territory)

But if you have really add a lot of them i would make a seperate page of "Other open formations "

As promised, I looked at my copy of 'Go Proverbs Illustrated'. :study: The part on five stone in a row on the third line in a corner is, alas, only one page.

It has two diagrams:

And it has a few small paragraphs explaining how they live.

It does not discuss the possibility of the attacker starting with the 1-2 point.
