R8C8 is the only square in row 8 that can be <7>
Squares R3C2 and R7C2 in column 2 form a simple locked pair. These 2 squares both contain the 2 possibilities <38>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.
   R5C2 - removing <3> from <123> leaving <12>
   R8C2 - removing <3> from <123> leaving <12>
Intersection of block 4 with column 1. The value <3> only appears in one or more of squares R4C1, R5C1 and R6C1 of block 4. These squares are the ones that intersect with column 1. Thus, the other (non-intersecting) squares of column 1 cannot contain this value.
   R1C1 - removing <3> from <2348> leaving <248>
   R3C1 - removing <3> from <3489> leaving <489>
   R7C1 - removing <3> from <348> leaving <48>
Squares R1C3 and R8C3 in column 3 and R1C7 and R8C7 in column 7 form a Simple X-Wing pattern on possibility <3>. All other instances of this possibility in rows 1 and 8 can be removed.
   R1C9 - removing <3> from <2348> leaving <248>
Squares R3C1 and R3C9 in row 3 and R7C1 and R7C9 in row 7 form a Simple X-Wing pattern on possibility <4>. All other instances of this possibility in columns 1 and 9 can be removed.
   R1C1 - removing <4> from <248> leaving <28>
