BQM 404

  Difficulty: Beginner   Keywords: Life & Death

In the book Tesuji by James Davies the following solution is given for the problem:

Black to play and save all his stones.  

Chapter When liberties count, Section Gaining Liberties, Problem 1, page 73. This is the book solution.

Possible White Continuation.  

But what is the correct answer to this W4?

Possible White Continuation. Black Response.  

LukeNine45: Something like this. W2 and W4 are interchangeable. White can trade a for b before playing W6 but to no avail. White loses by one liberty.

Possible White Contination. Failure Diagram.  

Dave: Careful! If Black carelessly answers W6 with B7, White has an indirect ko after W8. Black can not play at a. The right answer to W6 is to throw in at 8 first and then play 7.

Possible White Contination. Solution Diagram.  
Possible White Continuation.  

How should black answer W2?

| kb: B3. W suffers from damezumari.
