Life In 19x19

Sorry for unearthing this thread after a long time - I have just dusted off this book from my bookshelf in order to refresh my memory. In chapter 3 (group with eye vs group with no eye) I'm now stumbling across the problem positions No. 4 and 9 (which are actually the same positions just with black ...

at n1 instead of n3 would have prevented a lot of problems.

I still don't understand why is a small move? Doesn't that secure territory more than 2 points? With you are slightly enlarging an already fully-alive group of your own by maybe ~ 5 points. It does not put any pressure on white, i.e. white has full freedom to continue with whatever he wants (that ...

If you check this game with Leela Zero, you’ll find that Leela sees white in advantage almost throughout the entire game. While it may on the first glance look better for black (due to the large “moyo” or whatever in the upper half), there are obviously a number of flaws/weaknesses in blacks shapes ...

Here are my variations on Q1 and Q2. If they are wrong/incomplete I would be glad about corrections.

[...] Other than that, I just seemed to fall slowly behind. [...]
I would disagree and say that both players were more or less equal regarding the direction of play, but the game was rather decided by some important tactical details.

One example is the atari in move 33. In the game, white ...

Yes, wbaduk's english client has a somewhat strange user interface. I would recommend the following:

On first startup after installation, a settings dialog pops up. I strongly recommend going into the "flash" section and checking every box. Checking a box means to turn the respective flash sequence ...

I think it works much more simple: As most people don't like pondering too much about their mistakes, they are interpreted as a personal 'style', maybe like this:


⋅  Making overly cautious moves, giving away sente --> calm and solid style
⋅  Cutting in hopeless positions ...

Oh, yes! The thread went to the top for some reason, the month fits, and I didn't look at the year number. Apart from that, some problems take quite some time to solve, at least for me ...

Very nice idea for a new thread!

My attempt for the 1st position:


Edit: 2nd position:

At move 238 you mentioned that it’s one move too early. But actually, it’s (locally) necessary right now. Can you see, why?

Edit: On a second glance there is even another “side way“ making the capture unnecessary again.

Is this a 6-stone handycap game?

I would have played the same as Tryss, on first instinct, however it can get a bit tricky:

[...] Probably hard to answer generally, but I'll try anyways: What are some good black responses to the marked approach and when should they be used in regards to the whole board situation . Could you show some specific "whole board situations", which you have in mind (maybe it occurred in one of ...

Yep, we discussed that also already in our post-game coredump. I seemed to have a blind spot at the subsequent Q5...

@Tryss: Very nice picture

I just played a game on KGS which reminded me of my old "messy games" thread...
