This problem is of dubious origin. I copied this diagram from a tsumego collection composed by Ishida Yoshio 9p for the 24th Hiratsuka go festival; but, as there are some classic problems within the collection, it is not certain whether this is an original problem by Ishida or not.
Black to play.
Solution
Black’s cut of 1 is the only promising starting move, and 2 is White’s strongest resistance; white 6 instead would get easily captured by black 4.
Following, Black needs to be careful to realise to continue with 3. Black 5 then sets up a liberty problem for White in the corner, and after black 7 White has no way to survive.
If Black carelessly plays the atari of 3 instead, White fights back with 4. After this, there is no way for Black to capture White unconditionally.
