Life In 19x19

@Control, keeping s13 dead is very big, not just for points but also for safety of the right group and giving m9 group somewhere safe to run. Would you suggest something like m7 instead? I think black would s12, get the r10 peep and then s14 and say whatever white does on lower side he can't close ...

Regarding the game between Iyama and Ke, Ke's S13 then Iyama's answer look somewhat questionable to me. Wouldn't it better for Iyama to look for a move that takes care of center or bottom or maybe both?
