Since a few weeks ago i finally got my Tesuji problem books i've decided to share the splendid! Here are a few problems of different difficulty and sort for you to try and solve!'
Read the comment section for some hints to each batch of the problems, black to move first in all of them.

That's some awesome reading. I'm usually pretty good with these types of problems, but I just stared blankly for a while at this one.

Thank you! Although I have to admit, that I didn't read it all in my head! I originally only read it to the end of the first diagram and thought I was done, but when I looked at the diagram before submitting my answer, I realized that 'a' worked, so I had to read some more!
Concerning the rest of the problems: I think I know the right move for Page 1, Problem C, but can't read through all the variations! For Page 3, Problem B, I see a ladder, but it runs out of the diagram, so I don't know if it's supposed to be the solution!

If a ladder runs out of "the zone" with nothing blocking it, the ladder works and probably is the solution.
Regarding Zwergesels solutions:
Both of your solutions are correct, impressive reading on the geta problem. Its easy reading but quite long

In that case I see this for Page 3, Problem B:

White connects and you get an ordinary ladder:

Wow I had a massive blind spot for this problem Page 3, Problem A:

Good work so far from all of you! All the problems except C and D from page 1 is from Segoe's tesuji dictionary the other two from graded go problems for danplayers.
The Segoe book's is awesome and i recommend it for everyone that wants a good collection of different practical tesuji problems.
The only warning is page 1 problem A is quite hard. I couldnt solve it myself so cant really guess the level of it but the solution is quite sweet
If all becomes solved ill put out some new ones when i solved some more myself so i got some personal favourites.
Daniel_the_smith:
Gw both correct, i like the solution on B, not that incredibly hard but quite stylish when you see and understand it.
connects, 
at a captures everything!
That's some awesome reading. I'm usually pretty good with these types of problems, but I just stared blankly for a while at this one.
