seems like there are only a few cases where its a good idea.
if W is going to win the ko, then B will have lost the points they spent
to continue to ko to no end
if B wins the ko, then the ko has to be more than the cost of white’s last
(insufficiently large) threat, plus all of the points that B spent to continue
the ko.
so it seems like theoretically yes, but you’d have to count threats…or i guess
the ko is so damn big you’re gonna lose regardless, so why not?
