There are some possible reasons for not detecting diminished returns. Three that
immediately pop to mind are:
 Odd/Even discrepancies.
 Big depth needed.
 Low quality in chess evaluation functions.
The last reason is briefly illuminated in the article: Search Versus Knowledge
in Game-Playing Programs Revisited, by Andreas Junghanns, Jonathan Schaeffer. As
an ordinary chessgame is longer than both othello and checkers games the
combination lower decision quality of chess and longer game makes decisive
errors mor likely. Then chess is a hotter game than the others, maybe so much
hotter that diminishing return never materializes.
