Problem Corner

Europe Echecs features an (excellent!) quaterly retro-colummn. In addition, it also runs a monthly Problem Corner, devoted to chess composition in general. Recently, this column started publishing a few light retros here and then. I'll try to gather them in this page when they appear...
