I don't have a choice, I need to get out and attack something from my weak position. I think I'm fine so far.

And it's full speed ahead, cap'n! So far, I love how the fuseki is going. But I better not get arrogant yet. Sur absolutely destroyed me the last time we played because of one move. I must make sure to keep my groove going.

I love this fuseki now. And I'll just take the time to thank Marcus for showing this to me. I'm sure I would have seen it at some point, but this truly opened a lot of doors for me. It really made me take a strong look at the fuseki. And I think my fuseki today is at least five times stronger than what it used to be. Again, that might sound like an arrogant statement, but I really believe my studying is paying off.

Now, if only the rest of my game could catch up....

Continuing the moveset. Exactly as I predicted. Nothing new to say here. Actually, I changed it up a little.

From :w8: I've been forced to play like this. I don't see any other sequence for me. I am surprised that hailthorn didn't play anything greedy, but he has an excellent opportunity to do so now :-P

He probably studied this opening a lot. I am not familiar with it at all, but I didn't have any opportunity to make a mistake yet.

I think that the game has yet to start, as this is just a learned opening with no side making any mistakes or awesome moves.

is it really a known fuseki, considered even, so far ? i find the result good for black. maybe the right was joseki but it seems to be well suited to B set up
In theory, there is no difference between theory and practice. In practice, there is.

@Perceval:
Apparently it is joseki (per eidogo), but it looks better for black to me too. The sequence says black should extend at P7 next, but Q9 looks so tempting to me XD

I also used to really dislike this fuseki as white, but found I was consistently not making reducing plays around a, which I think can be important.

Also, white becomes thick: So part of the payoff from this joseki will be seen in the upper right, for example.

But this doesn't look much better and W's shape looks bad. 'a' would be a good point to help this group but B gets another solid group at the right with this. All other options W has seem to help B even more.

I think that's fine for white, and is the old fashion. But my understanding is it fell out of use as rather than playing at 19 black plays severely at 'a', so to avoid that white now usually plays the hanging connection joseki they are playing.

As for white looking small, and black big, you just need to be patient. Don't forget that black has a huge hole at h3 so his territory is not so big. Often black will soon play f5 to fix that and white usually answers at d2 which is a big move too to secure the corner and has large yose continuation at f2 and may even help support an invasion. The invasion at a is supposed to be dead, but it's only just and the killing variation no longer works if white has a stone in the n8 area.

Loon's suggested reduction at m5 would make sense if black has defended at f5. If he hasn't then it seems rather generous as h3 is better. The peep at b is some other aji white has to aim at.

This reminded my of some of my games which I think can illustrate the ideas. The first, http://www.online-go.com/games/board.php?boardID=96210, has a similar Kobayashi shape but a standard 3-4 joseki in the lower left corner. This became over 70 points of territory but I still won. Be patient and don't be jealous!

The second, http://www.online-go.com/games/board.php?boardID=76151, features the m3 invasion. l3 should be at m4 to kill. As you can see in that game as white runs out, using the aji of the p5 cut, black's bamboo group in the lower right actually comes under attack as it does not have definite eyespace. One reason white can attack so severely is the white group on the right is very thick so black can't lean on it to get free moves in sente to help his group escape. In fact white could have killed it, can you find his mistake?

@perceval, obs
I'm glad Uberdude covered all the details so well.

Some background: hailthorn decided to study this opening only just recently, after I used it playing a game against him on KGS. This was once (and probably still is) one of my favourite openings, and I played with it a lot from 7/6k to about 4k. Like Uberdude said, playing White here can feel a bit taxing, if you aren't familiar with the weak points of black's formation. For this reason, many players try to avoid playing against it.

At this point in time, I really don't mind playing as White against this. There are always interesting options, and it's good practice for White when it comes to keeping track of territory ad finding good ways and good times to reduce and/or invade.

I strongly encourage SDK players to check the opening out and play both with it and against it. There are a lot of lessons to be learned. (I guess that's true of any opening ... but this one is special to me! ;) )

Depending on my mood I will sometimes play to prevent the Kobayashi opening. But the primary reason is not that I don't like the position for white, but I've played it many times and find it rather boring.
