Life In 19x19

My bad -- I am indeed talking about , not . Sorry for the confusion.

I saw the move G15 from common joseki dictionary.

Also thank you for pointing out may be wrong -- I am wondering what I can do to limit white moyo, and I should have worried about that much earlier.

Thank you for the feedback.

* W15 should be at G15 in the joseki, Is there a typo here ? Not sure what you mean.



What I mean is that, the move number 15 by white is typically at G15, if white does no tenuki.


* I was not sure where to play at B26. Not a big problem.

I am black at this game.

My biggest trouble at this game is that I am seeing white building a lot of influence, and I do not know what is the best way to reduce it. My "invasion" at left is bad (as it leads to the death of the lower left corner, very ...

I lost this game because I let my opponent build too much in the center.

I was trying to get territory on the side here and there, thinking that if my opponent only has one big chunk of territory, it would be difficult to win. As it turns out, I am giving away too much center, and my side territory ...

Hi,

The following are some questions I have while I study some joseki patterns. It must be easy for advanced player, but somehow I cannot figure it out. Your help is very appreciated!

$$W One joseki variation ...

Depends on the board, but seems simpler to just do this as black:

In Kogo's joseki dictionary, it is suggested that black can play to get sente:
$$Wc Competing for sente

Thank you for all your responses!

In the actual game, my opponent did not choose the variation as Uberdude has worked out in great details (thanks!) My opponent got sente, though, and he immediately reduced the influence of my wall. So this is really a problem of wrong direction of play -- I chose ...

The following is one joseki on two space high pincer from Kogo's joseki dictionary.

I am playing black in this game. I have tried to attack three weak white groups, but I do not think I attack them efficiently. I resigned after I made a mistake in my third attack.

Some questions:

1. When white did not complete the ...

When I reviewed my games that I lost recently, I realized that there is a common theme: I often pick a wrong spot in invasion or in reduction, leading to either dead groups or my opponent get a lot of points elsewhere.

An example is the following. I invaded at (a) in the game, but that gave black ...
