In Response To: Retrograde chess problems (Nack Ballard)
I have one of the Smullyan's books and have borrowed the other from the public library. As Nack mentioned, the problems do get progressively more difficult. Actually, my favorite type of chess puzzles are studies which have great practical value because they resemble positions from otb play. Some chess problems are highly esoteric due to their contrived nature or theme - for example, helpmates.
As someone who is mainly concerned about otb play, I am very impressed by Nack's ability to quickly determine a sequence, over 30-ply(!), that would lead to a particular position and most importantly, assuming reasonable if not perfect play. Before I was aware of Nack's reputation as a master of puzzles; now I know he's the "real deal".
