Whiteboard Sunday – First Joseki #3
Source: akashayi
Welcome to the 3rd edition of Whiteboard Sunday. You didn’t write in the comment section what you wanted to see next, so I’ll continue analyzing the first joseki in the next few articles. This joseki is one of the most often played, so mastering it, will give you an advantage in real games.
Diagram 1 — Basic Situation
Last time I added few black stones and discussed black follow-ups. It’s time to look at white follow-ups. For this I will add one white stone to the basic diagram from a week ago. The topic of this article is Diagram 1.
Diagram 2 — Placement Tesuji
If black doesn’t defend the corner, white can attack it very severely. White 1 is basic move to shrink black’s eye space. Next white 3 is a tesuji. Black is in big trouble. What can he do?
Diagram 3 — Basic Answer
The first thing that comes to mind is connecting to black 1. Unfortunately thanks to the marked stone, white can connect very easily. The outcome is very bad for black. There must be another way to handle the situation.
Diagram 4 — Black Tesuji
Black 1 and 3 are tesujis to handle the situation. This way the white attack is not so severe. It is important to descend with black 3 and not at T18. The next diagram will show why.
Diagram 5 — Greed
If white blindly tried to capture one black stone, he would be trapped after black 6 in Diagram 5. As you can see black 3 from the previous diagram is important for black 5 at Diagram 5 to work. Of course white won’t play this way.
Diagram 6 — White success
Instead of white 3 from the last diagram, he will play the hane. This way the outcome is decided by the ladder at A. If the ladder is good for white, then black can’t defend two points (A and B) at the same time. In such a situation black 2 from Diagram 2 is mistake.
Diagram 7 — Black choice
If the ladder from Diagram 6 is bad, black can play the exchange of B for C, or jump to D instead. The B-C exchange is pure and simple, but the jump to D needs more study.
Diagram 8 — White disaster
Thanks to the marked stone, the ladder at A doesn’t work. The result is very bad for white. This diagram closes this week’s topic. Next I will discuss this joseki from a territorial perspective.
Diagram 9 — Black to play
Of course, there is also a problem for you to solve. Like always it’s black turn to play.

Wow, this is great stuff! It’s fundamental and common in games, but I didn’t realize some of these variations >__<. Keep up the good work :).
Great lessons, I keep putting stones on board. I have question about move D on dia. 7. If this is a move for black instead of A, how can we repeat moves from dia. 2 (to get dia. 8)? White’s 3 is an answer for black 2 in S18, not for O15.
I upload your situation to eidogo: http://eidogo.com/#1uExX8di BTW you can change avatar in comment section if you want. Just use gravatar.com
Thanx, now its clear. I first thought that with black’s D on board white won’t play 3 tesuji (dia. 2) at all.
This is a real interesting series, and very enjoyable. I would be interested in seeing some 4-5 joseki variations as well.
I don’t feel strong enough to write a lot about 4-5.
When I end series of basic joseki to 4-4 point I will try to write about something easy in 4-5 joseki ;p
I understand. Thanks for the consideration. It doesn’t matter what you choose to write about, I can learn a lot from your articles. Thanks, and keep up the good work :)
Ugh, whenever I start feeling comfortable with my skill level I learn something new that makes me realize I’m not thinking ahead enough. But that’s Go for you.
Thanks :)
