I encountered a variation of aforementioned joseki that gşves me headaches and prepared a demoboard.
The main joseki text is at move five.
A variation I often encounter and its deviation is described at move twelve.
The position that gives me headaches is to be found at move 23.
The best result i can find for white is a one step ko wit black taking first. Something unbearable in the opening.
If i cant resolve this i even have to think about the answer at 6. as I think it is a one-way street for white thereafter.
If you’re interested. This is how it played out in a pro game of Lee Sedol’s that just continued pushing from outside and made W play 158 to to get the C9 and B8 moves
I’ve frankly always hoped that no one would play this deviation against me ever since you brought it up since I was stumped as well but I found this play that seems satisfactory for W. Though I wouldn’t say it’s punishing B for deviating at all.
