It seems that you are referring to Capturing Races 1. The only noteworthy term invention there is "fighting liberty". It makes a complicated thing simple because it allows the statement of the extraordinarily simple (and correct!) New Semeai Formula dF =? 0 for the basic semeai Classes 1 + 2. So 48 cases are summarised in one formula. The 1 case of Type 1 Case 7 is a seki. The remaining 44 cases are trivial (initially a major string in atari etc.) and so players can choose to ignore them.
Previously, matters were more complicated (and incorrect in some cases); part of the explanation is in the Correcting Mistakes in Literature chapter, where the nasty concept Forced Liberties is criticised.
Capturing race is simple counting
It is not simple counting because a) one must know WHAT to count and b) HOW to compare Black's and White's numbers.
(You would not believe how many dan players do not know the number of approach liberties of a 5-point eye...)
and no asian study that topic
Thanks for the confirmation;)
it is like learn the theory of addition to college level student.
No, it is (still) like theory of addition for pupils just above elementary school. When there are complicated approach moves and kos, the theory will reach (partly in research papers elsewhere has already reached) the level you fear.
if you want to improve go skill you should watch 2 top ranked professionals game with professionals comment.
Professional games are a good source for learning but professuonal comments too often are of the uninformative "this move is good, believe me" level. Have you ever seen a pro commentary with a proper positional judgement of the whole board? Maybe it exists but I have not seen it yet. Even such basics are missing in pro commentaries!
Not what is theory of ko
Ko theory is and will become more fun indeed:)
