R1C7 is the only square in row 1 that can be <3>

R1C1 is the only square in row 1 that can be <4>

R3C3 is the only square in row 3 that can be <8>

R4C5 is the only square in row 4 that can be <3>

R5C6 is the only square in row 5 that can be <2>

R5C3 is the only square in row 5 that can be <3>

R7C2 is the only square in row 7 that can be <1>

Squares R5C1 and R5C5 in row 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <56>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R5C4 - removing <5> from <159> leaving <19>

Intersection of row 3 with block 3. The values <19> only appears in one or more of squares R3C7, R3C8 and R3C9 of row 3. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain these values.

R2C7 - removing <1> from <126> leaving <26>

Intersection of block 1 with row 3. The value <6> only appears in one or more of squares R3C1, R3C2 and R3C3 of block 1. These squares are the ones that intersect with row 3. Thus, the other (non-intersecting) squares of row 3 cannot contain this value.

R3C5 - removing <6> from <567> leaving <57>

R3C7 - removing <6> from <126> leaving <12>

R3C9 - removing <6> from <679> leaving <79>

Squares R3C2 and R5C5 form a remote naked pair. <56> can be removed from any square that is common to their groups.
