Intersection of row 4 with block 6. The value <5> only appears in one or more of squares R4C7, R4C8 and R4C9 of row 4. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain this value.

R5C8 - removing <5> from <3456> leaving <346>

Intersection of row 5 with block 6. The value <4> 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.

R4C8 - removing <4> from <456> leaving <56>

Squares R7C2<489>, R7C3<49> and R7C7<48> in row 7 form a comprehensive naked triplet. These 3 squares can only contain the 3 possibilities <489>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R7C5 - removing <8> from <568> leaving <56>

R7C8 - removing <4> from <457> leaving <57>

Squares R7C8 and R9C9 in block 9 form a simple naked pair. These 2 squares both contain the 2 possibilities <57>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R9C8 - removing <57> from <3457> leaving <34>

Squares R6C6 and R6C8 in row 6 and R9C6 and R9C8 in row 9 form a Simple X-Wing pattern on possibility <3>. All other instances of this possibility in columns 6 and 8 can be removed.

R5C8 - removing <3> from <346> leaving <46>

Squares R3C2, R3C3, R7C2 and R7C3 form a Type-1 Unique Rectangle on <49>.

R7C2 - removing <49> from <489> leaving <8>
