Thanks to Robert, Thomas , and Nick for their contributions.

My main motivation for thinking about Seki was/is the question
if it is possible to recognize upcoming Seki situations in the
histograms of an MCTS bot (for instance in Crazy Analysis).

An interesting game is between Aya (White) and Zen (Black) from
round 15 of the 13x13 KGS bot tournament back in August 2015:

 Hi Robert,

thanks for the whole bunch of very intersting information.
 Seki has AT LEAST two groups....
 Sekis can have various different shapes ...
... stable anti-sekis (stable because other anti-sekis exist elsewhere on the board).
Can you give an example for anti-seki?
 Listing the possible configurations is a demanding open research field.
Perhaps you and someone like Thomas Wolf (with his life-and-dath background) would be "the right" people for this question.

I have an (unpublished) talk about sekis online:

I am grateful for any references about literatur on seki and any examples of
strange, exotic seki.
