R7C1 is the only square in row 7 that can be <7>
Intersection of row 2 with block 3. The value <4> only appears in one or more of squares R2C7, R2C8 and R2C9 of row 2. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain this value.
   R1C7 - removing <4> from <2457> leaving <257>
   R1C8 - removing <4> from <247> leaving <27>
Intersection of column 4 with block 8. The values <36> only appears in one or more of squares R7C4, R8C4 and R9C4 of column 4. These squares are the ones that intersect with block 8. Thus, the other (non-intersecting) squares of block 8 cannot contain these values.
   R7C5 - removing <6> from <268> leaving <28>
   R8C5 - removing <6> from <25689> leaving <2589>
Squares R7C5 and R7C6 in row 7 form a simple locked pair. These 2 squares both contain the 2 possibilities <28>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.
   R7C3 - removing <8> from <1368> leaving <136>
   R7C7 - removing <28> from <12468> leaving <146>

R6C9 can only be <9>
R4C9 can only be <5>
R2C8 is the only square in row 2 that can be <4>
Squares R7C5 and R7C6 in block 8 form a simple locked pair. These 2 squares both contain the 2 possibilities <28>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.
