Minue
Notice : I'm Minue622 on KGS. I made this page as a teaching board for my KGS padook pupils, so the solutions to these problems will not be provided on this page.
And I need some help. Anyone who can remove "table of diagrams", leaving "table of contents"...?
tderz: Minue, here you are, removed TOC, ... as requested by you.
Belly attachment move
The following are the problems that we will see and solve. Problems 1-10 are intermediate level (Kgs 5k~1d), and the rest are advanced ones.
I took three problems (problem A,B and D in advanced section) from chinese classical Go literature - "Guan ja bo" (관자보-官子譜 : korean pronunciation of the title of this book, its literal meaning is "The management of stones )
1 - Problems of intermediate level (1-10)
Problem 1) : Upper right corner - B's turn to play.
This position can happen when black plays tenuki against w's 3th line corner approach. Using the belly attachment move (too much of a hint?), B can make miai and, capture one of w's stones - or
Problem 2) : Lower right corner - W's turn to play.
For white, is a good move,(meak). Black played
, seeing the miai of 'a' and 'b'. Now problem is how to defend against this black's attack for White.
Problem 3) : Lower left corner - B's turn to play.
This position is from Black's 5-4 move joseki. is just its overplay. Black can save its 2 stones, capturing
or
stones. We assume that ladders are always good for black.
Problem 4) : Upper right corner - B's turn. B can kill marked 2 white stones in corner.(This problem is a very easy one)
Problem 5) : Lower left corner - B's turn. Move 'a' can not work. So, something brillant(?) move is requried for black to kill corner white. Ko fight is the best for both [2].
Problem 6) : Upper right corner - B's turn.
This position can happens when white plays double 3th line approaches to black hoshi. In this variation, was a really big mistake(so_called "thank you move"). White should have not played atari move. Due to White's big mistake(
), black could play tenuki(
).
Now, white is trying to get rid of black's base with ,
.
Black's goal is to keep its corner base, killing these White's 2 stones(,
).
Problem 7) : Lower left corner - W's turn to move.
This is acutally the same with problem problem(5). white should make 2 eyes in corner, preventing black's expected tesuji,
Problem 8) : Upper right corner - W's turn. Save marked its 2 white stones in corner. (Hint: Read out what will happen if white cut at 'a'.) [1]
Problem 9) : Lower left corner - W's turn. Save corner white. This position can happen when W invades at 3-3. Usually, is not a standard move (this implies that this black move is not good, generally...)
Anyway, Black seems to hope to kill and
, playing
. But For white, there is a simple way to make 2 eyes in corner, preventing B's belly attachment move.
(Hint: Actually, this is exactly same with problem (8) )
Problem 10) : Upper right corner - W's turn.
There is simple and clean(no ko fight) move for white to kill corner black. Easy problem, No hint.
2 - Problems of advanced level
Problem A) : Upper right corner - W's turn. This problem is of white's best yose move in black's corner, using aji of white's marked stones. W can not save its marked 2 stones, but can make something(?) cool in b's corner.
Problem B) : Bottom side - W's turn.
Against ,
is one of expected black's resisntance, but it can not work. W can get huge profit, playing brillant "meak". The goal is to kill black's 6 stones in left side, or destroy black right side territory completely, killing black 3 stones.
Problem C) : Right upper corner - B's turn.
Now, Black has just one eye. To make one more eye. Black should kill one of w's mark stones and save it. We alreay saw how to make miai by using belly attachment move in problems (1-3).
Problem D) : Bottom side - W's turn. White cut, black played atari agaisnt it. Now, Can white kill black 7 stones on right side? If so, how to?
(Hint : Actually, this problem is similar to problem (4) in intermeidate level section )
Problem E) : Upper right - W's turn to kill black.
The first thing to do is to read out why W's move 'a' can not work to kill black. Next, after finding W's right attack move, then think about black's best resistance agasint "White's right attack" and what is reasonable result for both.
(Hint : As always,,, belly attachment move is very effective to make miai)
3 - Jeong suk and the use of belly attachment move in it: Old version and comtemporary one ( Rui naiwei jeong suk)
Upper right corner sequence is showing its start. Upper left corner sequence is the old version and, lower left one is comtemporary jeong suk (so-called Rui naiwei joeong suk).
4 - Case study. From Sakata 9p's game
This position is part of Sakata 9p's game against Fujisawa Shuko 9p which he played in 1960.
is one of the most famous moves of Sakata. We will discuss this position and the reasons why this
's attachment move was very effective for defending white's dragon on bottom side by examining relevant variations...
[1] /discussion
Notice - I wrote this section just for tim. So, this topic will not discussed in my lessons for other padook pupils.
How to connect.
1 W's turn to connect"
1) Think about what is the most efficient move to connect from 'move - a' to 'd' for white at this position.
2) Also, think about w's best way to connect to defend its weakness in lower left corner.
2 Some simple cases
This is a simple quiz for fun. How many ways(moves) is it possible for white to defend its weakness at 'a'?
More specifically, think about how many moves are there for w to defend w's weakness 'a' so that white can save its marked 2 stones after black's cutting at 'a'.
3-1 Problems (Basics)
In all of following problems, B's turn to play.
3-2 Problems (intermediate)
Problem G(Upper side) - Black can save its marked 2 stones, or kill white in corner, making miai.
Problem G(Bottom side) - Save one marked black stone, or kill white in corner.
4 More things to think about.
It's not always good for us to connect and save our stones. Sometimes, Letting opponents to cut and capture our stones is much better, sacrificing them. These 2 positions are elementary cases in which sacrificing is much more profitable for us.
we will discuss how to play agasint 's threat to cut, and examine some relavant variations.
