Single Position

For column 9, Number 1 is only possible in cell (9,8)

Single Position

For column 7, Number 6 is only possible in cell (7,3)

Single Position

For box 8, candidates for 6 are all in column 6, so you can remove candidates from other blocks.

Candidate Lines

For box 2, candidates for 1 are all in column 4, so you can remove candidates from other blocks.

Candidate Lines

Candidates for 7 in boxes 1 and 3 force the candidates in box 2 to be in the remaining line.

Multiple Lines

Candidates for 8 in boxes 2 and 8 force the candidates in box 5 to be in the remaining line.

Multiple Lines

Naked Pair for 2 and 7, can remove these as candidates from other cells.
