R3C1 is the only square in row 3 that can be <1>

R2C7 is the only square in row 2 that can be <1>

R8C5 is the only square in row 8 that can be <3>

R5C5 is the only square in column 5 that can be <8>

R7C6 is the only square in column 6 that can be <5>

R8C7 is the only square in column 7 that can be <9>

R9C7 is the only square in column 7 that can be <2>

R9C9 is the only square in column 9 that can be <8>

Intersection of row 8 with block 7. The value <2> only appears in one or more of squares R8C1, R8C2 and R8C3 of row 8. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain this value.

R7C1 - removing <2> from <2489> leaving <489>

Intersection of column 5 with block 2. The value <6> only appears in one or more of squares R1C5, R2C5 and R3C5 of column 5. These squares are the ones that intersect with block 2. Thus, the other (non-intersecting) squares of block 2 cannot contain this value.

R3C4 - removing <6> from <2346> leaving <234>

Intersection of column 7 with block 6. The values <57> only appears in one or more of squares R4C7, R5C7 and R6C7 of column 7. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain these values.

R4C8 - removing <7> from <478> leaving <48>

R5C9 - removing <57> from <3457> leaving <34>

Intersection of column 9 with block 3. The values <56> only appears in one or more of squares R1C9, R2C9 and R3C9 of column 9. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain these values.

R1C7 - removing <6> from <46> leaving <4>

Intersection of block 2 with row 3. The values <23> only appears in one or more of squares R3C4, R3C5 and R3C6 of block 2. These squares are the ones that intersect with row 3. Thus, the other (non-intersecting) squares of row 3 cannot contain these values.
