There is an excellent blog (in Greek) about culture and Over-The-Board chess and chess problems, (see here), run by the Schroendiger's Cat.
Some weeks ago a post was published there (by the reader Kaloproeretos) about the distance between the world of OTB chess and the world of chess composition.
The conclusion was that the chess players would benefit if they knew the chess problems better.
As a result, a series of about 150 compositions of many kinds, selected by Kaloproeretos, started to be published, for the chess players to be familiarized with chess problems.
If you follow the links you will see these selected problems.
Try to solve them. (The answers to the problems of one post are published below the problems of the next post).
Sorry for not including here a proper translation of the Greek text.
