In a recent game on IGS between MyMaster and kobe (B) an interesting position arose which deserves a bit of attention and is a wonderful source of reading problems.


[Diagram]
The position diagram  

The moves to W3 are a direct attack on Black's group and are worth a bit of study. W1 is on the vital point of the black group's eye shape while W3 is a tesuji for preventing Black from connecting to the right.


[Diagram]
The importance of playing on the vital point  

If White plays here first, then Black has no problem living with B2. This is still a good result for White; but if White is able to kill the black group then this diagram is a failure. So White must sit back and start reading before deciding on whether to attack the group, or to take the small profit by taking just three black stones.


[Diagram]
The above is NOT a good result for white. It is infact a flower ko for black  

white must play the Ko, or lose his entire group. Black risks nothing...

David

Huh? I failed to finish this page. Can you please explain which white group is in danger David? Also can you explain why white plays 5?

The continuation...  

Black pulls out a tesuji of his own and if you haven't read it all out you might find yourself lost for a continuation. What to play and what not to play next will be the source of the material for this page....

Goran

edit: Goran had the first move, I added 2. this doesn't work

David

Well why don't you try a different move then :). I said this was a reading problem.

Goran

Matt: In this case D6 and and F6 are Miai, though F6 seems to lead to less complications.

[Diagram]
Continuing Further...  

I think there might be a problem with move #2... Shown in the previous diagram... Because after Black plays 1 here then White has the choice of giving up 2 stones or letting Black connect out... So he saves his stones by playing at 2... After 5 Black is connected out :D ~ Sleeper

Dieter's attempt.


[Diagram]
Start a capturing race  

BramGo: B1 has a lot of variations which all reach the same position.

[Diagram]
A one way road...  

BramGo: After this sequence, the white group at the lower side of the board cannot live without a difficult capturing race.

[Diagram]
Capturing race...  

BramGo: After W9 the capturing race continues and black has 1 more liberty... Unless if there's another way to play the capturing race ?
