OneThousandAndOneLifeAndDeathProblems/Problem 325 discussion

my answer  

I thought there should only be one correct answer for these problems, but as best as I can see, both moves work for black. Responding to white is identical in every response except one, but white still dies. Am I missing something, or does this problem have two right answers?

white dies  

Phelan: I don't have the book, but from what I read, it seems the answer they give only sacrifices one stone, while yours sacrifices two.

fractic: That doesn't make any difference on the score Phelan.
