@Doctor-Phibes Chess problems are always white to move. If it takes about 10 minutes to solve, you can be sure it is not an easy move.

Didnt know a word about the different oils, I will read more.

Maybe this is my favorite chess problem. Maybe the hardest mate in one that I have seen. It is just check mate in one, so It can not be so difficult... but it is!!

I do really love it because it can take more than 10 minutes to solve it.

Some years ago we made a chess book for kids and we included some satanic chess problems as this one.
Leonid Kubel is the author of this problem.
