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.

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
