Your most obvious next move is r1c4 = 7.

-- There's a triplet of {3, 5, 7} in r5c6, r6c5, & r6c6.
-- So you can remove "7" from r5c4.
-- That leaves a triplet {2, 8, 9} in r4c4, r5c4, & r9c4.
-- So "7" is the sole candidate at r1c4. dcb

This part of the forum is about puzzles posted on the
Daily sudoku site. With which date is this one associated?

If it is an 'external' puzzle, the topic should be moved.
