R7C9 is the only square in column 9 that can be <4>
Intersection of row 1 with block 3. The value <2> only appears in one or more of squares R1C7, R1C8 and R1C9 of row 1. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain this value.
   R3C7 - removing <2> from <1236789> leaving <136789>
   R3C8 - removing <2> from <12678> leaving <1678>
Intersection of row 9 with block 7. The value <5> only appears in one or more of squares R9C1, R9C2 and R9C3 of row 9. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain this value.
   R7C2 - removing <5> from <1359> leaving <139>
   R7C3 - removing <5> from <1235789> leaving <123789>
Intersection of column 1 with block 1. The value <6> 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.
   R2C3 - removing <6> from <13679> leaving <1379>
   R3C3 - removing <6> from <1345679> leaving <134579>
Intersection of block 8 with row 7. The values <15> only appears in one or more of squares R7C4, R7C5 and R7C6 of block 8. These squares are the ones that intersect with row 7. Thus, the other (non-intersecting) squares of row 7 cannot contain these values.
   R7C1 - removing <1> from <179> leaving <79>
   R7C2 - removing <1> from <139> leaving <39>
   R7C3 - removing <1> from <123789> leaving <23789>
   R7C7 - removing <1> from <126789> leaving <26789>
   R7C8 - removing <1> from <12678> leaving <2678>
Squares R1C2 and R7C2 in column 2 form a simple locked pair. These 2 squares both contain the 2 possibilities <39>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.
