Dango
Path: ShapesAndConnections · Prev: BigBulge · Next: Diamond
Dango means 'dumpling shape', and refers to a solid mass of stones without eyes and few liberties - a very inefficient shape.
The stones are an example of this (from squeeze tesuji).
-- Morten Pahle (10kyu)
Phlegmatic: Here's an example of an incredible dango that my opponent created:
In this sequence it became clear to me why the proverb says Beginners Play Atari, although my responses were atari plays too, so who am I to talk?
I think it's true to say that here are 13 black stones that have only 5 liberties, and have captured no firm territory yet (and only 3 white stones). I guess heavy and inefficient are the polite terms for this scenario...
This made me think of the dango as a kind of cancerous tumour growing in the heart of one's play, drawing in the host's strength and storing up trouble for the future. Characterising them in that way will definitely help me focus my mind on dango-avoidance in future.
-- Phlegmatic (19kyu KGS)
unkx80: Certainly Black can play double atari here?
Phlegmatic: Black was showing a stubborn refusal to sacrifice stones that, to my shame, was making me get careless. If Black had played here, it would be no less than I deserved.
Jan: Black 4 in the 'the dango swells' diagram seems at first glance very silly to me. Surely Black can play 4 at White 5?
Dieter: Given the peculiar form of the dango I am sure he was under some kind of influence.
BadShape: Yeah, that's pretty extreme for normal Go. However, this is not a big dango at all by the standards of the Go variant called Dango, where captured stones are moved, not removed, so you can use them to fill in an opponent's eyes. I still recall when a friend and I achieved the ultimate dango feat - an entire board seki, consisting of just two groups. Boy, how we laughed about how silly that looked. Maybe we were under some sort of influence too.
Quacki: Just yesterday, I read my Ranma 1/2 Manga Book (german, Band (volume) 30, I think), which give a translation for dango. It said dango means "balls of fishmeat on a spit" ("Fischbaellchen am Spiess"). Does this have anything to do with our dango?
kokiri: Dango are usually desserts, pounded rice balls filled with azuki beans or the like. I've never heard of fish dango, and frankly I'd be a bit suspicious of the translation, but yes the original dango is a foodstuff.
Large Dango from extreme handicap play
16 stones in actual play ...
Problem diagram [0]: How could this happen? (cf. dia. [99] or [5])
Let's have a look at some logical sequences. (Logic has little to do with real truth or reality)
dia. [1]: Tderz: This Dango could appear if Black plays too submissive and small-point-focussed several times.
At the same time, White is playing trying to achieve the Dango in actual play.
is overdoing things? If B11 at a, Wb can connect or capture in a ladder. If B11 at c, White can live.
dia. [2]
dia. [3]: and
want to prevent the white connection underneath, which is ok in itself.
Black could vary with , but
is a nice tesuji.
dia. 3a?: is a nice tesuji too, preventing momentarily the connection underneath (cf. with dia. [10]).
dia. 3b?: -> a,
-> b
dia. 3c?: Black cannot deviate much ...
dia. 3d?: are able to live now - Wa with weak ko b for Black - who must avoid white c by black d (allows Wf or Be (allows Wd). OK, the latter is not so interesting, but if Black was able to play all this, s/he wouldn't need handicap ....
dia. [4]: continuation from dia. [3]: is small-scale thinking again.
dia. 4a?:
dia. 4b?: ->
? or
at a is not urgent for either
dia. [5]: continuation from dia. [4]: ->
dia. [6]: next is aiming to capture all ^^...
Just found by chance in "Breakthrough to Shodan", page 9, dia. 4 another variation how to produce this Dango:
dia. [7]: Exchanging for
strengthens White more than Black, a (question: or b?) are better.
dia. [8]: B18 commits a mistake to complete the trap.
should be at a (follow dia. [10]).
dia. [9]: The are not well positioned.
dia. [99]: at
.
dia. [10]: is tesuji (cf. with dia. [#3a])
connects. After
, another important move follows:
dia. [11]: is tesuji (cf.
in dia. [3]) and avoids the ko of Wa-e.
Tderz Who could/would add variations starting from diagrams [2], [3] and [4]?
