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.

Is it possible you transposed elementary and intermediate?

@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.

For 17C I would try the following...
...or the other way round:
$$B
Click Here To Show Diagram Code [go]$$B
and then...
$$W

W seems pretty dead in both variations, please correct me if I'm mistaken.
Edit: I am obviously hallucinating in both lines, so never mind...

Sverre, your solution to the elementary one is wrong.

Wrong as in dead or wrong as in inefficient?
Is this better?

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.

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.
