M 20

I had made a thread where I displayed one of my wonderful puzzles and I went searching for it and the link is dead. 

This is the link: https://www.chess.com/forum/view/more-puzzles/m-20-de-yi-de-yi

It says "404 page is not found". 

Do you make these puzzles yourself? If you do that is seriously impressive

I would assume so, because not attributing puzzles created by others can cause serious trouble.

The double double-check at the end is amazing. I have never seen something like this before! I saw the idea on move 17 and it was great that you could make such a puzzle.

I may be impressive, yet I am not a serious entity... rather a bit silly!

Thank you all for your pleasant comments. I am happy that you like my puzzle.

Nevertheless, I do not understand why my thread-entry is not there anymore at "More Puzzles". (the link I have provided above)
