On Topasz' request I will open a new thread for every new series of problems.
#17 & #18 are in my previous thread. Sverre solved
#18 while
#17c is not killed yet unconditionally. ( there is no garantee it is possible, but about all were ) I give some additional time.
This threads tries to repeat the success of explo's tsumego problems at Godiscussions 5 years ago. I am just copying.

Elementary problem
White has a length-5 potential eyespace open at both ends. Two hanes in either order reduces him to a 3-space killable shape. The 1-2 point also kills, by bent 4.

White is threatening to split his eyespace and live. Starting at the 1-2 point is the only viable attack.
$$Bc B1 anywhere else, W plays 1

If W captures B's 4 stones, he is alive no matter what, so this is necessarily a semeai problem. Black can't make a big eyeshape but even a small eye can force the opponent to spend approach moves.
$$Bc 6@3
