Squares R1C1 and R1C3 in row 1 form a simple locked pair. These 2 squares both contain the 2 possibilities <46>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.
   R1C9 - removing <6> from <689> leaving <89>
Squares R1C9 and R2C9 in column 9 form a simple locked pair. These 2 squares both contain the 2 possibilities <89>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.
   R4C9 - removing <89> from <4689> leaving <46>
   R5C9 - removing <89> from <5689> leaving <56>
   R8C9 - removing <8> from <458> leaving <45>
R8C7 is the only square in row 8 that can be <8>
R4C8 is the only square in column 8 that can be <8>
Intersection of row 5 with block 6. The value <6> only appears in one or more of squares R5C7, R5C8 and R5C9 of row 5. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain this value.
   R4C7 - removing <6> from <469> leaving <49>
   R4C9 - removing <6> from <46> leaving <4>
