W can get a K.O,B can not kill.

I appears @mark5000 submitted that one - maybe he can explain?
It’s about the comment on an earlier position
A and B kill, but B gives a stone outside.
and A seems to be a ko.
Side note for @GreenAsJade when navigating back and forward a bit, say from the OP’s position, and then going through some variations I tend to get the joseki explorer freezing and no allowing clicks and the console showing
I think OJE is in need of some love, it’ on the list.
A and B not help is inaccurate description.
But B K.O,A die.
The sequence and the corresponding comments are sourced from Kogo’s Joseki Dictionary. I agree with others’ opinions that it appears to be incorrect.
Kogo’s is well known to have quite a lot of wrong information.
I don’t understand your objection. First, there is already a stone at S18 so you can’t play there. I assume you mean T18 which is what @Atorrante shows in his diagram. But then Black just plays T17 and kills, if they ignore whatever ko threat W makes
Edit:S19 T19 S19
But kill with K.O not it kill(generally used to represent kill without K.O).I think this a error.
