Well specifically, I want to know about F, but I figure its important for all styles, as Kouma tends to create a lot of these situations.
Is the 5b 2b 5c OS techpunish after corner 623b or 623c for F Kouma supposed to be able to cover neutral techs as well? I can only seem to cover back and forward with it. If i do it early enough to catch neutral the 5b whiffs on forward and back.
