Life In 19x19

I only vaguely understand the go theory in this post, but I have been absolutely convinced that the author is an amazing writer.

A first solution might be to simply use the AI to characterize the skill of players and the skill level of specific games.

1.) Find the average winrate change (i.e. move 1 deviates from the AI's top choice by some percentage, called the move's delta for players) in a specific rank by analyzing a ...

Updates!

So, I bought six of Robert Jaisek's books. So far so good. They have the feel of a textbook, which is nice. Some of the principles are easier to say than to follow, like "Do not play superfluous moves" in Endgame Fundamentals. This is certainly good advice, but no one would play a ...

You left out e . I didn't think much about e before I wrote my previous note. Now I think it might be a better reply for White than c , because it leaves more plausible options for Black, only one of which works. Aside from finding the solution to the problem, that's worth knowing. :)

If e, then ...

I guess for reading practice, it's best to consider every variation.

You don't need a problem to practice reading. :) To solve a problem you don't need to consider every variation, just every relevant reply of the opponent. (If you're not sure that a reply is irrelevant, pretend that it is ...

I didn't mean to suggest that, only that the top bots prefer the corners over the sides more than humans have done. (OC, that doesn't mean that the bots are right. Top bots 10 years from now may have different ideas. :))

As I did explicitly suggest. :)

Yeah, I probably misinterpreted your ...

I started to go through OTME (Opening Theory Made Easy) today. Lo and behold, the first principle Otake (9p) discussed was essentially the same idea that Bill suggests is wrong.

Now, my first instinct is that this situation is bad for white. Black is ahead and ...

I am afraid that the bots have made Opening Theory Made Easy obsolete. Best to check your moves with a bot. Meanwhile, I have written up some ideas in this series: https://lifein19x19.com/viewtopic.php?f=15&t=16909

That thread looks interesting. I am not sure, however, that an obsolete theory ...

Alright, I am updating my study plan slightly. Maybe if my results are good, others can use this thread for ideas.

First, I am adding some books that I read (or half-read) a long time ago. First, I have heard that rereading books can be useful. Second, I want to solidify my conceptual understanding ...

Is this actually happening? When is the release planned?

On endgame:

For endgame counting and tesuji I highly recommend Lee Chang Ho's Endgame Techniques (2 volumes), available electronically on gobooks.com. There are some other good modern endgame books that I will let others recommend, but I really like his methodical but readable approach.

Thanks ...
