Life In 19x19

A few small remarks to your last posted game:

On move 26 I would just solidify the corner with D17 and ask the single black stone, what he wants there. If he tries to escape you will take profit in the corner and on upper side; if not it's also no problem


Regarding your "punishment" in the upper right corner, I think it works if you made the solid connection on O16 instead of N16:



Edit: The corner positions were all shifted by one line...

Y that would be definitely better than my having to tenuki two times and get him all secure and everything, cause there was no reasonable move there.

I'd be happy as black with this. My corner is safe and all is connected and strong.
And white gets almost zero: he shfits potentially territory somewhat, but only occupies dame points and the influence of 3 is cancelled by the strengthening of blacks extension.

Wouldn't you be happier if B played as in the next diagram, leaving the weakness at 'a' ...?

This looks like B has just learned to play go. But in fact, this is the joseki you showed. The joseki just shows s14 exchanged for s16 already. If you can be happy with the first diagram, you should be even happier with the joseki.

As White yes, as black not. I dont quite get what your aiming at.

And a is a sente possibility to make the weakness dangerous. As in the game i already had a stone in that area it -

All this is not possible in your first diagram.

After looking at these josekis they dont look much different than what was played in the game- I guess there is some move order opportunity fo black to thwart this line, if white cuts at first (like in game), but i would have to study that more. Also could be that it's just better in terms of ko threat usefullness.

arg edit war.

Ah, okay, I see the confusion. I thought your comments ("that would be better," "I'd be happy as black with this") were referring to the diagrams below the comment, but actually you were critiquing schawipp's suggestion and understand perfectly well why the joseki is better.

As you say, your result in the game (at 53) strengthens B's corner compared to joseki, but since you can still get a result similar to the joseki on the right side, you don't need to be too upset.
