R4C8 is the only square in row 4 that can be <8>

R6C2 is the only square in row 6 that can be <2>

R8C1 is the only square in row 8 that can be <6>

R8C5 is the only square in row 8 that can be <8>

R3C9 is the only square in row 3 that can be <8>

R1C4 is the only square in row 1 that can be <8>

R3C5 is the only square in row 3 that can be <6>

R9C6 is the only square in column 6 that can be <1>

R8C6 is the only square in column 6 that can be <4>

R8C3 can only be <5>

R8C9 can only be <7>

R9C2 can only be <9>

R8C7 can only be <2>

R7C2 can only be <1>

R1C6 is the only square in column 6 that can be <2>

R2C7 is the only square in column 7 that can be <7>

R2C9 is the only square in row 2 that can be <6>

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>

R5C1 - removing <3> from <359> leaving <59>
