From the dango page
16 stones in actual play ...
Problem diagram : How could this happen? (cf. dia.  or )
Let's have a look at some logical sequences.
(Logic has little to do with real truth or reality)
dia. : 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 at a, Wb can connect or capture in a ladder.
If at c, White can live.
dia. : 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. ).
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. : continuation from dia. : is small-scale thinking again.
dia. [4b]: -> ? or at a is not urgent for either
dia. : continuation from dia. : ->
dia. : 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. : Exchanging for strengthens White more than Black, a (question: or b?) are better.
dia. : commits a mistake to complete the trap.
should be at a (follow dia. ).
dia. : The are not well positioned.
dia. : at .
dia. : is tesuji (cf. with dia. [3a])
connects. After , another important move follows:
dia. : is tesuji (cf. in dia. ) and avoids the ko of Wa-e.
Tderz Who could/would add variations starting from diagrams ,  and ?
