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

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.
