R5C8 - removing <69> from <15689> leaving <158>

R8C8 - removing <9> from <189> leaving <18>

Squares R4C8 and R6C8 in block 6 form a simple naked pair. These 2 squares both contain the 2 possibilities <69>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R5C7 - removing <9> from <189> leaving <18>

Intersection of block 4 with row 5. The value <9> only appears in one or more of squares R5C1, R5C2 and R5C3 of block 4. These squares are the ones that intersect with row 5. Thus, the other (non-intersecting) squares of row 5 cannot contain this value.

R5C5 - removing <9> from <469> leaving <46>

Squares R6C5, R6C8, R4C5 and R4C8 form a Type-1 Unique Rectangle on <69>.
