Some Novel Chess Problems
Who moved last?
A chess problem is a work of art hidden in a chess puzzle.
In 2000, I discovered that I love designing retrograde analysis chess problems ("retros"). The objective in normal chess problems is to speedily checkmate the opponent, but in retros the future of the game is more or less irrelevant; instead you have to use detective skills to figure out events in the history of the game.
When I was a young one, I enjoyed Raymond Smullyan's book "The Chess Mysteries of Sherlock Holmes", which is still the only popular introduction to the retro field, but the problems are "elementary" :-) and it lacks a bibliography. At some point around that time, I met the friendly endgame specialist A.J.Roycroft, who sent me a chess problem magazine, containing one extremely challenging retro which at that age I completely failed to comprehend. The composition was based on the 50 move rule and I now realize that the composer, Nikita Plaksin, is legendary in this area. Anyway, stuck between the too-easy and the too-hard, I put the subject down. Some life happened.
Thirty years on, I stumbled across the curious idea that became "Dead Reckoning", and started a correspondence, still-continuing, with Noam Elkies, who introduced me to chess problem composition, and to the amazing souls who are part of this world. I was hooked!
Over time, I broadened my composition interest to other areas of composition, particularly proof games and helpmates. I also retain a fascination for quirky interactions of the rules and conventions.
Here are some proof games:
There are also a few easy helpmates, many of which have a retro flavour:
