Thanks for the responses. 1) I guess for this seki question I was wondering if it was as easy to define as liveness without seki. The reason I am interested in this is I am curious about absolutely correct scoring functions and whether they currently cope well with advanced seki situations or n

Well I was hoping for a static definition which could be assessed with minimal calculation. The problem with a definition relying on a best move metric in my mind is that "best move" is a very difficult thing to define in go since we do not (yet) have an accurate position evaluation function.

It's great to see incidents like this being handled with maturity. Also, a nod to Nick for having the humility to apologize, and Jason for not losing it. My respect to both has increased although it was already high. - Don Jason House wrote: My personal preferences would be to see t

Thanks everyone for the responses. My go skills are somewhat limited (only 6-7kyu on KGS) so hopefully I am not belaboring the obvious. I have a few followup questions- 1) What mathematically is a seki? I know this is a local draw but can it be determined statically at some point in all cases
