Note that in puzzle two the author is given as on this page. We are told (e.g. by Edward Winter in Chess Notes 4339) that "Ua Tane" was a Polynesian pseudonym for James Frank Stimson (1883-1959), a renowned American chess problem composer. He composed over 1,000 chess problems, of which about 200 were awarded prizes. He was also a prolific chess writer and editor. Reader Marjan Kovacevic tells us it took Stimson weeks and months to create.
The following video descriptions of the problems were made by Frank Scarpa and appeared on his Youtube channel Chess for Charity. Frank's declared goal is to spread the amazing game of chess while helping those in need. Half of all income earned on YouTube goes directly to charity.
Frederic FriedelEditor-in-Chief emeritus of the ChessBase News page. Studied Philosophy and Linguistics at the University of Hamburg and Oxford, graduating with a thesis on speech act theory and moral language. He started a university career but switched to science journalism, producing documentaries for German TV. In 1986 he co-founded ChessBase.
