dsatkas: There are many problems like this which say w or b to kill, when best option is ko. It's more fitting to say w or b to play if you don't want to give away the fact that it's a ko
d4rkm4tter: It is planned to change the description for those problems to "Black to play." So please continue mark those problems.
Hello, This problem is still marked as "X to kill", instead of "X to play".
