Swedish Fuseki

Figure 1: Swedish fuseki  

This 'fuseki' was made up in the Swedish channel on KGS partly because they wanted their own opening, partly as a joke and partly since God said that 6-7 is the best opening (confer with Chinese fuseki, Korean style of Baduk, etc.).
This should in no case be considered a good opening ;)

A Swedish opening begins with a 6-6 or a 6-7 in one corner and followed up by a 5-5, 6-6 or 6-7.

The Swedish fuseki has mainly 4 strengths:

• Confusing the opponent. The seemingly (only seemingly?) worthless starting moves can throw your enemy off guard.
  Also, many players will notice that you build a large center moyo and will put a lot of effort into destroying it. Sometimes, to the point that they will de facto sacrifice several moves to destroy it while you can peacefully build up a large territory on the sides.
• Fewer life securing moves. All of the groups on the board are quite well connected and in case life is needed, its not that difficult to make eye here and an eye there. A move which otherwise would be needed to secure the base isn't needed.
• Favorable ladders. Since you control the center, ladders will likely be in your favor.

The goal of the large corner enclosing Swedish fuseki, a variation of the Swedish fuseki, is to surround each corner and build side/center influence. If black, Tengen is usually the first move.

Example sequence and likely not a joseki.

(Upper right is an example of how the fuseki user should emphasize the sides/center moyo).

A more useful variation would be the corner enclosing Swedish fuseki where the moves are played closer to the corner in a sequence that aims to end in sente.

In order to succeed with this fuseki, the opponent should ignore your approach and play in another corner, before surrounding the last corner. You then attack the corners with sente attacks which will give you side/center moyo in exchange of cutting points ripe with negative aji. The last corner is usually left open.

(Personally, I kind of like the small corner enclosing SF)

Following this method, White renders a large and stable corner for the price of a strong enclosing on Black's behalf. White may want to continue with the marked stone, from which a similar sequence follows. If Black succeeds with enclosing the left side, he is in an eminent lead according to proponents of the strategy. The marked black stones make for fair future threats for Black. White, on the other hand, would like to play at the circled black stone, both for territorial gain and to disrupt Black's shape. By omitting 5 and instead play moves such as 6 or 7 immediately may also be possible plays for Black. Move 8 is supposedly sente for Black as, if not countered, the following scenarios may occur.

Figure 4.I.II: Omitting 17-15, variance 1  

White here stretches for the left side, sacrificing the 16-16 group and giving Black an enormous lead.

Figure 4.I.III: Omitting 17-15, variance 2  

Here, White chooses to rather sacrifice the 15-17 group in order to save the 16-16, once again a great bonus on Black's behalf.

Now what?  

Or, if Black gets the circled points, will White be able to make territory at or near the squared points?
