1 KYU KR_NYAN (R1891) BEATEN BY THE AUTHOR

White wins by 8 points, komi 7.

[Diagram]
 

This is the fourth game on the road to 2 dan. At the time of this writing, Black is 3 dan (R1871), which might be his actual rank.


[Diagram]
 

B1 is a contemporary opening, popularized by Go Seigen. It is ready to create outside influence if Black is attacked at triangle.


[Diagram]
 

W2 is a mirror reply, just to create the most balance shape.


[Diagram]
 

B3 is an early attack. Normally weak players avoid it because their strategies are territory-oriented. Strong players, on the other hand, have adaptive strategy. They decide the next move by the opponent's camp, not by the free land available.


[Diagram]
 

W4 is to claim the left region. Whole board thinking shows White is physically inferior, but the big komi makes them actually balance.


[Diagram]
 

After B5, Black seems to occupy the large north east region. And, white+square is being attacked. I want to help it and, to be efficient, must attack Black at the same time. This is double-purposes strategy.


[Diagram]
 

So, I hane with W6, which aims at triangle. Black has to choose between S and T.


[Diagram]
 

Black pushes with B7. He expects White to fill at square and then he will seal at triangle, which will ascertain the large territory is his.


[Diagram]
 

White cuts with W8 rather than filling at square, which surprises Black. Now the black army is divided into two units.black+cross is hard hit and needs help.


[Diagram]
 

B9 is natural; otherwise, black+cross will get killed. It seems like White is being squeezed and needs to fight both sides at the same time.


[Diagram]
 

W10 is somewhat receptive, but it creates weak points of Black, at cross. It also unites the white army, forming a Berlin wall that influences both sectors of Black.


[Diagram]
 

Black though the weak points are too many, so he put B11.


[Diagram]
 

W12 affects black+cross directly and indirectly. White now forms a great wall, hard to kill.


[Diagram]
 

Black's most urgent task is to help the two black+cross. The question is how? He has to surround enough space, in correct form, in order to live. He begins with B13.


[Diagram]
 

The purpose of B13 and B15 is to widen the base, a basic strategy for survival. The purpose of W14 and W16, on the other hand, is to squeeze or confine Black, in order to make Black live in hardship.


[Diagram]
 

The fighting until B17 not only affects Black's bottom group, but also influences Black's top left group.


[Diagram]

W18 is not as small as it seems. Imagine what will happen if Black can jump freely with black+square.


[Diagram]
 

B19 is a must unless there is somewhere bigger to play.


[Diagram]
 

W20 is simply to escape while almost killing black+cross.


[Diagram]
 

Black enjoys tracking with B21. To here, Black seems to occupy the large two corners, whereas White is being squeezed. White needs to create a big turning point in order to win. This is called "Believe in your dreams and making them reality."


[Diagram]
 

Black wants to hane at triangle and then square in order to kill white+square. If allowed to happen, this battle would lead Black to victory. Therefore, White should do some big attack before. Big attack means an attack that could kill a big group or cause a vast territory damage to the enemy.


[Diagram]
 

W22 is big. If ignored, it is a basis for white jumping to square, and will possibly kill this black group.


[Diagram]
 

Black wants to arrest white+cross at square. Beginners will defend at square, but stronger players don't. A better reply is to fight back at triangle.


[Diagram]
 

For more annotation (from W24 to here), see The Art of 9x9 Go. At the end, White (the author) wins by 8 points.
