R2C6 is the only square in row 2 that can be <7>

R5C9 is the only square in row 5 that can be <7>

R7C3 is the only square in row 7 that can be <3>

R6C3 can only be <4>

R5C8 is the only square in row 5 that can be <4>

R6C5 is the only square in row 6 that can be <3>

R5C1 is the only square in row 5 that can be <3>

R8C8 is the only square in row 8 that can be <3>

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

R9C8 is the only square in column 8 that can be <6>

R2C2 is the only square in block 1 that can be <6>

R4C3 is the only square in row 4 that can be <6>

R5C3 can only be <1>

R4C7 is the only square in row 4 that can be <1>

Intersection of row 3 with block 2. The values <16> only appears in one or more of squares R3C4, R3C5 and R3C6 of row 3. These squares are the ones that intersect with block 2. Thus, the other (non-intersecting) squares of block 2 cannot contain these values.

R1C5 - removing <1> from <14589> leaving <4589>

R2C4 - removing <1> from <158> leaving <58>

R2C5 - removing <1> from <1458> leaving <458>

Intersection of row 6 with block 6. The value <8> only appears in one or more of squares R6C7, R6C8 and R6C9 of row 6. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain this value.

R5C7 - removing <8> from <2589> leaving <259>

Intersection of row 7 with block 8. The value <4> only appears in one or more of squares R7C4, R7C5 and R7C6 of row 7. These squares are the ones that intersect with block 8. Thus, the other (non-intersecting) squares of block 8 cannot contain this value.

R8C5 - removing <4> from <145689> leaving <15689>

R8C6 - removing <4> from <4689> leaving <689>

R7C6 is the only square in column 6 that can be <4>

Intersection of column 1 with block 1. The value <5> only appears in one or more of squares R1C1, R2C1 and R3C1 of column 1. These squares are the ones that intersect with block 1. Thus, the other (non-intersecting) squares of block 1 cannot contain this value.

R1C2 - removing <5> from <145> leaving <14>

Intersection of column 1 with block 7. The value <9> only appears in one or more of squares R7C1, R8C1 and R9C1 of column 1. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain this value.

R8C2 - removing <9> from <1489> leaving <148>

R9C2 - removing <9> from <189> leaving <18>

Intersection of block 5 with row 5. The values <268> only appears in one or more of squares R5C4, R5C5 and R5C6 of block 5. These squares are the ones that intersect with row 5. Thus, the other (non-intersecting) squares of row 5 cannot contain these values.

R5C2 - removing <2> from <259> leaving <59>

R5C7 - removing <2> from <259> leaving <59>

Squares R3C7 and R5C7 in column 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <59>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R6C7 - removing <5> from <258> leaving <28>

R7C7 - removing <9> from <289> leaving <28>
