The first half of the book contains short commentary on 4, 3, and 2-stone openings (50 to 60 moves). Instead of jumping straight to Shuwa's games I started playing through the 4-stone openings and I am enjoying them. Given Shuho's brevity and lack of rationale, I am following Fairbairn's suggestion to understand for myself why Shuho bothered to comment on a particular play. But having gone through several 4-stone openings, I am wondering whether the plays and commentary are even relevant today?
For example, I often see black playing the 4th-line attachment against the keima kakari (attach and extend variation): https://senseis.xmp.net/?44PointLowApproachAttach. Usually in response to a double kakari (which was allowed) but sometimes immediately. Sensei's states that AI does not favor this joseki. I also see the olde ogeima from 4-4 shimari/response. But does this even matter in a handicap game? Is this not a good joseki for a "beginner" anymore? Or is it still fine to use in handicap matches? And some of Shuho's commentary goes beyond what I would consider as the opening.
What do you think? Is it worth my time reviewing historical handicap openings or has AI changed the handicap openings as well?
By the way, I also own "Handicap Go" (Yoshiaki & Bozulich, 1982), which might be considered historical at this point.
========================================

Shuho says that black's trade taking the middle point on the upper side for white's second kakari on the right-side is "very good" for black. So, better than the "good" that Shuho typically uses.
Shuho say's that ignoring White's kakari against the lower-right corner to play the pincer on the center of the left-side against the white group in the upper-left is "one idea." Hm...
