Sergueï Kaminer: The Unknown Draft

Hello Viewers!
I am back with a beautiful composition with it's earlier draft.
Please check out my other blogs; I will be happy with a lot of views, and don't forget to comment on the quality of the positions!
As a starter, you can try to solve the draft first. Here we go:

I hope that wasn't too difficult. I am sorry if it was :/

Later Kaminer published another composition: this time he improved the above position and won the 2nd Prize in Shakhmatny Listok! Here we have it!

Hope all of you enjoyed this post! It has been my longest so far, and as usual, thank you for reading and solving the puzzles! Bye and see you until my next blog!
