Michael Traut: Its quite hard to guess what you mean with "how many moves".
Black & White moves? Only Black moves? Or Black moves that are not answered locally?
Maybe "locally unanswered moves" would be clearer.
Zerodan: The question is a bit uncertain. One should ask about how many liberties the group has. If black answers, white has to make more moves than the group has liberties.
guile: Hello Zerodan,
The question is asked this way to emphasize that this dead group won't be naively killed in 4 moves.
This approach makes sense with the following problems introducing the "fastest way to kill" and the associated Tesuji in L-Group.
