5 years ago explo published a series of tsumego problems. I just found them again. If there is enough response I will republish them here. For historical reasons I start with nr 17. Please mention the nr of the problem(s) you are addressing in the subject title.
17B applied in "joseki" (I almost resigned in shame with that dango):

Is it possible you transposed elementary and intermediate?
The best I see for the third problem is a ko... F18 f17, e18 e17, d19 c19, f19 g18. If Wg18 instead of c19, b captures and w loses the race by a lot... A structural deformity at e18 reduces him to a 4-space eye.

I don't understand thread, but thank-you for posting tsumego problems : )
I would like to see tsumego forum here where people can post and solve problems all day.

@jts : quite possible. The elementary one took me a few seconds; more than the intermediate. But I only copied them ( without permission ) from explo's previous threads in Godiscussions. @uberdude: I imagined you were blond. Probably because of the "uber". @logan: don't try to understand. I take care of the problems, everyone else ( except Sverre ) of the solutions.
Wrong as in inefficient: living with 4 points in sente (well, maybe white doesn't connect but then you have a 7 pt gote yose for later) is unconditionally better than living with 3 points in gote.

What's that supposed to mean?
Well, you were the master solver 5 years ago, so you are discharged now. But OC you are most welcome to participate. I remember you solved most problems by at a18.
