Re: Advice on evaluation

[Joan Pons Semelis <joan@xxxxxxxxxxxxxxxx>]

I think the problem of group strength should revert to the
same treatement as ladders: PN, at least a kind of fuzzy one.
In the most simple way, with a2 liberties chain we check if
it can get 3 or more if it's friendly move or atari ( or geta )
if it's enemy; if it has only one (snap-back aside) we only
check to gain liberties. 
With group strength the evaluation to decide if it's instable
it's more complicated than "1 or 2 liberties", the moves to
try to find out the result more and more difficult to find
(a tesuji library would help) but ought to be basically the
same.
