mgoetze: leads to seki, unless White is prepared to risk the entire group on a ko. It would probably be better to play
at a.
Gronk: B has to win the ko at b for this to be seki. If Wb then W may play at a to make life without seki.
Gronk: White can sacrifice the for life, no? The order of
and
may be interchanged. Still, the correct solution (below) is better.
Velobici: Doesn't White a appears to settle the position in White's favor?
mgoetze: Yes, which is exactly why I said it would probably be better to play there...
Alex Weldon: Good. This is the correct solution.
