It's getting creaky, isn't it, showing its age? The first "chapters" were written years before the last ones, and if I had known I was going to write some of these things I would have organized it all differently.
I know that several subjects have appeared more than once. Perhaps this is disorganized and rambling. I'd rather hope that each time I revisit a subject, I approach it from a different angle and add new ideas to it; but I freely admit it's disorganized.
When I started to write part 5, which is about the difference between endgame values and midgame values, I had a hint of the ideas I was going to discover, but I really invented them as I wrote.
I found part 5 to be rather revolutionary.
During part 6, I was thinking about it, and now I'm going to take you back to the idea of calculating the values, with of course some new insights.
