Because nobody liked the previous ones here some others.
It is hidden because the left side shows the solutions of the previous problems.
As a sidetrack we can teach ourselves japanese by deciphering all the characters, like from Rosetta's stone.

I have no idea how to solve problem 190, as far as I can tell Black is dead.

Among these three problems, I found 190 the hardest because I initially focused in the wrong area.
Hints for 190:

BTW, that should be
around 10 kyu, not
less than 10 kyu.

Last call for problem 190. Come on, you guys. It is only 5 to 6 kyu. One long one way street. ( 11 moves )
Besides, it is very instructive. Never encountered such shape in your games before?

Second try. I was spoiled by unkx's hint though.

Here's my try for 190:
$$ 190 - Starting setup

$$|.5OXX..
$$|.3OX.O.
$$|.OXX...
$$|41OXOO.

$$ 190 :b7: @ :b3: - "a" stops White connecting after :b5:

This is a two step ko, with Black taking first?
EDIT: Maybe the other side?

$$|.8OO.O.
$$|7XOXX..

This is a direct ko if White plays
@
, or in the sequence above where White connects, with
capturing again at
Presumably White will fight the ko the first time though, and can play
as a ko threat (because it's still a direct ko anyway)?
FURTHER EDIT: Actually, isn't this a two step ko again? Go is hard
