I think he would have been slightly better off with a tenuki.

The reason is because this makes his stone heavy.

Remember in 9 stone handicap games, where there's a common joseki:

This is good for black, because white's stones are heavy.

But then somewhere along the line, you learn that it's bad to "kick" the stone in a "normal" game:

$$ | . . . . . . . . . . . . . . . . . . . |
$$ | . . . . . . . . . . . . . . . . . . . |
$$ ---------------------------------------[/go]


That's because, if black plays "a", above, white can extend around "b". Similarly, if black plays "b", white can press down around "c". The two areas are like miai, so it's bad for black. Black has tried to make white heavy, but really, he just tried to do too much.

In the game, I already have a stone to make white heavy. This makes things strikingly similar to the 9-stone handicap joseki:

$$ | . . . . . . . . . . . . . . . . . . . |
$$ | . . . . . . . . . . . . . . . . . . . |
$$ ---------------------------------------[/go]


The difference is, of course, that the bottom right corner has the opponent's stones, and not my own.

However, I believe that the principle is the same. My pincer stone is in a great spot to make the two marked black stones heavy:

$$ | . . . . . . . . . . . . . . . . . . . |

$$ ---------------------------------------[/go]


Whereas the marked white stone, on the other hand, is high and light. :cool:

I totally agree with topazg and disagree with Kirby. Black is doing well in this fuseki, I think. :b7: is totally normal, :w8: feels like an overplay, because a pincer at one of the points marked 'a' now looks perfect for black. White has separated his own stones.

Better would be (I think) to play :w8: at :b9:, or, alternatively, tenuki. Yes, if :w8: @ :b9:, black can take the corner easily. But white's thickness will be more than worth it...

yes. it is an over play somewhat.
but i would have played same sequence if i was kirby.

Well, time to start the fireworks already. White's play feels like overplay to me, as I get to extend from my shimari whilst attacking - if I can get the point on the middle right later, Black should have a good game. I assume White's going to jump out, and then so should I, I think.

I was just going to post how I don't like the position for black at all, when I noticed a quite crucial mistake in the latest diagram :P

Topazg's latest is the kind of move I'm never sure wether to make or not. On the one hand, it does take territory while attacking, but on the other hand I'm sometimes afraid that moves like those are thank you moves, in that they just let the opponent fix their aji and solve all their problems.

Thoughts on telling the difference?

Then B usually plays around 'b'. Playing at a seems strange here...

I am seriously contemplating tenuki-ing to play around the center on the right (I'm not quite sure which point, yet, though):

On one hand, I can't help but feel that such a move will get people to yell at me in hidden comments. I recall many a time when Bill Spight has called me out for ditching a stone that I've played earlier. Would this be another of those times?

On the other hand, I can't really see how such a play is bad for myself. I decided not to play yet, because I should try harder to see if I can see how such a tenuki could be bad. But I cannot play in a certain way just because I feel that kibitzers would want me to play that way. I must convince myself that a tenuki is bad, before deciding against it.

But to be honest, at the moment, a tenuki looks very appealing.

By the way, I think topazg's last move is a good way to move out, locally.

I think it is exemplary that Kirby is thinking deeply at this juncture. Decisions now shape the game.


More trivially (my strategic opinion);
topazg's prospects on the bottom makes splitting the right like this feel passive, I think. I would play K5 immediately even if I intended to go elsewhere. However, this situation seems to call for more finesse than I am capable of.

*Edit: I prefer white on this board, even if I find the situation hard.

Possibly. :)

If :b2: extend, this is pretty painful for B:

Ed,
Your diagrams seem a little good for black to me ? I think to push black out ahead of him does not seem like the right exchange (my inclination is to move out with the diagonal move (kosumi?) and let black decide how to treat his weak group).

Yes, my first feeling was :w12: as a kosumi at :w1: instead of the cap (a):

Keep B separated, let B run out with (a), let's fight.
But now that W has capped with (a) and made things heavy (for both B and W), W cannot tenuki now.
If W wanted to tenuki to play a big wedge on the right side, W could've done it earlier,
but now it's too late to give up :wc:. Locally, for the current board, I'm not sure what is
W's best play, but W cannot tenuki.

As the guy who coined the phrase, "When in doubt, tenuki," I should be glad. ;) But why be in doubt?

If the purpose of :w12: was to sacrifice :wc:, then sacrifice it, e. g., with :w14:. If the purpose was to fight, fight.

If you are going to tenuki, I think that :w12: was the time. White has made a small profit on the bottom side by preventing the :bc: stones from making an ideal extension, and it is not so clear what the best way to attack is.

OK, so I've thought about this for awhile, and this is what I've come up with. The reason I feel like tenuki-ing is because I am a move behind with playing my earlier move:

Because I took the liberty of playing here, it is difficult to effectively attack white. That's because black has already jumped out, and if I chase him, black can always slide underneath my 4th line stone around the marked area:

Therefore, at this point, an attack on the stones will be rather soft. I still feel that the pincer is effective, because if I can make use of it later, black's stones are a bit awkwardly placed. Still, I do not think this is the time to make use of the stone.

But instead of tenuki-ing directly, I think that I need to get more value from the stone. With the move played, I can threaten to bring my stone to life, and get a stronger attack on his stones. If he ignores, the cut feels very good for me:

$$ ---------------------------------------[/go]


tl/dr: I want to get as much use out of my pincer stone as possible, but I cannot do this in a direct way since black is a move ahead in the local area.


Edit: I modified the last diagram, because I used the wrong number for the cutting stone.

To be honest, I rarely have a concrete plan on a move. Maybe this is a bad thing... :-) The rough idea at the time was that I do not want white to set up his stones nicely on the bottom. I think that that has been accomplished to some degree, but black may get some local profit if he captures my pincer stone.

I'd like to get as much profit as possible if that situation occurs.
