Life and Death from the Elementary Go Series has been an interesting book for me, given that it was the first go book I ever acquired.

I read the early chapters about basic dead shapes when I was DDK and it was like a revolution to me, but then the book quickly became too difficult for me. Months later, I picked it up again after several stones improvement and I learned the L groups - all of the sudden, L groups were appearing in all of my games. Tripods and J groups came next.

Now after more than a year playing go and approaching the dan ranks, I realized one day that ko's of significance were rarely occurring in my games and that was probably due to a blind spot in my reading. I'm reading the Hane for Ko section in Life and Death now and hoping to find a new resource.

One day hopefully not too far off I will be handling carpenter's squares routinely and all will be well with the world.

I mean what I write: Lessons in the Fundamentals is rather weak at conveying knowledge because it conveys very little knowledge while much more knowledge is needed for study. The book tells you "only" to study all the fundamentals but it almost does not tell what those are. It needs other sources for the actual knowledge. E.g., joseki principles, see my books. For every other topic mentioned in Lessons in the Fundamentals and every not mentioned topic, more such books teaching the fundamentals knowledge in detail are needed.
