Almost the same as Dusk Eagle. I missed the descent at in the first problem but if Black just captures White get's a Ko. I also found the sequence to in the second problem ( being the strongest counter, I think just playing this at or fails pretty fast) but then I was at lost when White connects at . But now after seing the move numbers it was fairly easy to find the following sequence ^^

I have the same solution to problem 3. Problem four needs some more moves, I guess. I found this Ko:

I was glad to see (when I gave up and peeked) that I am not the only one who can't get them all. One to go but no clue at this point.

#4 can be disorienting because there's a lot of back-and-forth and some tricky timing involved.
Number five actually has an interesting history. Originally it was aimed at saving the seven stones, but a mistake was found in the original solution; so its goal had to be broadened to 'which stones should Black sacrifice?,' allowing it to work once again.

White has a nice counter with . If Black continues to try and save his seven stones, he will be left with only one eye. However, this is just the beginning. Where to go from here?
I gathered these problems from some old Go World issues. However, I did do a small bit of tweaking. It's fun to collect problems from various sources and string them together into a flowing, thematic set (I should have a good example in this upcoming week's Journal entry).
As for creating problems, I wouldn't want to say that I've created any original problems over the years, rather I've modified the ideas of other problems to create my own variations from time-to-time.
Can we maybe get hidden solutions to these problems? I haven't learnt to post diagrams here but i'm clueless about problem #4. If white sacrifices a stone at move 4 the whole sequence seems fairly straightforward but I don't see a way to avoid damezumari (if we refuse to play the ko that is). Help!

I'm still with a Ko. But I'm prone to make stupid mistakes : D
