R5C9 is the only square in column 9 that can be <1>

Squares R7C1 and R9C1 in column 1 form a simple naked pair. These 2 squares both contain the 2 possibilities <24>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R5C1 - removing <4> from <3459> leaving <359>

R5C3 is the only square in row 5 that can be <4>

Intersection of row 6 with block 5. The value <7> only appears in one or more of squares R6C4, R6C5 and R6C6 of row 6. These squares are the ones that intersect with block 5. Thus, the other (non-intersecting) squares of block 5 cannot contain this value.

R4C4 - removing <7> from <3567> leaving <356>

R4C6 - removing <7> from <579> leaving <59>

Intersection of column 3 with block 4. The value <3> only appears in one or more of squares R4C3, R5C3 and R6C3 of column 3. These squares are the ones that intersect with block 4. Thus, the other (non-intersecting) squares of block 4 cannot contain this value.

R4C1 - removing <3> from <13579> leaving <1579>
