Seki unambiguous definition discussion
Keywords: Life & Death
Proposal for seki
Definition:
- A mutual liberty is an empty point that reaches two chains of different color.
- Two chains of different color live in simple seki if they reach no empty points but the same two mutual liberties.
Addition:
- A group of stones is alive in simple seki, if for any sequence of moves by the opponent, there is a sequence of answers that turns the group into a chain which is part of a pair of chains, complying with definition 2.

(TapaniRaiko: The proposal is not enough, as these two examples show. I have seen an example where a 35x35 board was filled with small groups all living in a single seki.)
