Hello,
@eleven, Cenoman
Very Nice!! Sudoku at the level is a form of art IMHO.
DPs are so powerful and give so much room for creativity!
Of course, they are also very handy for the manual solver,
but one has to develop a good eye to see them.
Beautiful moves like those renew one's motivation to keep
developing skills on DPs. Thank you!
Best regards,
jco
