Hi Brady,

I have a question regarding the tenth episode. Assuming that "urgent before big" still applies, why is it is not considered urgent for black to defend that group on the left? What is it about this group that makes it acceptable to play a big move elsewhere and let it get chopped up?

daal, I am terribly incompetent at diagramming on this board, but I will try.

In the meantime I would ask you to consider three questions.

1. Before black tenukies at D15, are the D5 stones cutting stones? In other words, is saving them really urgent?
2. How big are the three black tenukies at D15, K18, and O3? You don't have to be precise, just a rough guess.
3. If you assume black's two stones are dead after white E7, how much has white gained, versus what he'd have if black saved them?

Right, now I'll try to diagram.

1. No, they are not cutting stones, but they are a group that you said made a base, giving you ample compensation for white getting the corner. When are stones a group that is urgent to protect?

2. If we assume that a stone alone in a corner is worth 10 points, then another one there is probably worth an additional 8 pts. (wild guess)

3. It looks like white has secured an additional 10 points with the two moves, and has also taken away about 5 black points, so 7.5 pts/ move, not a big difference as far as my lousy calculations go.

Okay, my answers... (note, not a pro's answers.)
1. Before black tenukies at D15, are the D5 stones cutting stones? In other words, is saving them really urgent?
No, until white plays C7, these stones aren't cutting anything. So the first tenuki should be easy.

2. How big are the three black tenukies at D15, K18, and O3? You don't have to be precise, just a rough guess.
I'd estimate the value of the three tenukies at 15 points each (double komi), since they are reasonably efficient, and we are still in the opening. So a total of 45 points. (Note - This REALLY is just my opinion, and I'd love to know what others think.)

3. If you assume black's two stones are dead after white E7, how much has white gained, versus what he'd have if black saved them?
White has gained maybe 16 points in cash if you assume black D5 is dead. White also has really good invasion potential to gain more around a, so the value of his moves is certainly greater than 16. But is it anywhere near 45?

Hi Brady,

Damn, I did it as described in the how to make diagrams post. But your linked tool is awesome, and a reference to it REALLY NEEDS to be in post 1 of the "How to make diagrams" thread.

I've been on this forum for years, and I rarely made diagrams because it was too tedious. If somebody made it easy (Thanks Herman, I'm guessing!), then it should have been made REALLY obvious for future users. All IMHO, of course.

Does my new three second sad trombone count as a theme song?

I just caught up on Kevin's interview with Andy Okun last night, and in watching, I came to think that it's interesting that both of Jennie's students recently started streaming.

Is this just a coincidence, or did you guys coordinate to contribute as streamers?

Mostly coincidence. I think we have two different goals when doing these videos.

Mine is more just to do interviews than to teach Go.

Coincidence. We didn't even discuss our plans with each other. Funny, isn't it?
