Does anyone know this book wit 4000 puzzles?


There is no selection available.
No one has reviewed it.
It was literally just self-published. (last week)
37 Euros? for 4000 mate in 1 puzzles?
Mates in 1 don't sound very challenging.
The author is listed as Lennert A. Conrad. Is that you? Or is he related to you? ( You are listed as Axel Conrad.)
Look, if you self-published it, that was probably a lot of work. Why not just show a selection from it so people can see what you are offering?
