This site now hosts a complete archive of PDF versions of The Problemist Supplement, from 1992 to the current year. This magazine is aimed mainly at newcomers to chess composition, so it is recommended for those who want to find out more about chess problems. You can find the archive here.
My memorable problem is the changed double Grimshaw problem by C. G. S. Narayanan which
received first prize in The Problemist 1975 and deservedly received the Brian Harley Award
What is special about this problem? An obvious try (the judge said "who would not push that
WP?"), beautiful changes and wonderful construction. But what makes this more memorable is the
fact that I was there when this problem was finished by Narayanan and I helped check the final
version! What a day that was !
