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:

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...

When in doubt, play the most aggressive move

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.

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?

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. :)

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).
