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.

Among these three problems, I found 190 the hardest because I initially focused in the wrong area.
Hints for 190:
There is no way out on the right side.
The solution is a ko.

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?

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

@Topagz:
L&D wise, I see no difference between your two diagrams. I regard both as solutions (although I won't play the second diagram myself because the throw-in is unnecessary).
I think both are two step ko (http://senseis.xmp.net/?TwoStepKo).
