Getting ready

So the Swiss championship is approaching rapidly. Only 2 more months until the great showdown, time for a little training. I will be posting short summaries of what I have studied, maybe they’ll help you too 🙂 And since my opening kind of sucks, why not start with that ^^? (And I do realize that Onadare is more of a Joseki than a Fuseki… I’ll get to the real Fuseki-stuff later on :P)

Making this complicated: Onadare!

Making things complicated: Onadare!

Anyway, I’ve been encountering a hell lot of players on KGS that would use the nadare after a high approach, so having a look at Onadare seems like a useful idea. It’s one of those Joseki that take up to 20 or more moves and was first introduced by Go Seigen in 1957 (in a game against Takagawa Kaku). The basic development looks about like this, now there are 4 possible continuations, A-D. I won’t post all the variations in one blog, it would become a mess. So for today, I’ll start with option A.

Basic sequence after A

Basic sequence after A

This is the most common sequence after A (move 1). White cuts at 2 and Black secures the corner with 3.  Black then gives some shape to his center group with 5 and 7 while white solidifies his groups with 4 and 5. In this variation Black has some attacking-potential at the left side.

Hitting the vital point

Hitting the vital point

Instead of extending to 5 (see last diagram), Black can also hit the vital spot at 1. White is forced to secure his group while isolating the black stone in the center.  Black makes good profit at the top, while White will have to struggle with gaining an equal amount of points in the center.

pushing further

pushing further (6 below 4, sorry it got cut off ^^)

Blacks last option here is to push with 1. This move basically switches the outcome of hitting the vital spot immediately. In this variation Black gets a more solid group in the center that is not as easy to attack. While White can create a living group at the top with a good amount of influence at the top. Notice that Blacks shape isn’t that great yet. Black might want to reinforce it before playing elsewhere (making this sequence Gote for him).

dealing with the split

dealing with the split

White could follow an entirely different approach and split the two black groups at the top. To whites approach there is no standard answer. Ishida’s Joseki Dictionary proposes this variation with White extending at A and Black playing at B at the end.

However it is not found in many pro-games and is therefore arguably not really joseki. Different from the other variations this one lets White gain a much broader wall. It has however some more attacking spots.

The next varition I’ll blog about will be “B”. And always remember to study with your friends 😉
