R8C3 is the only square in row 8 that can be <5>

R9C9 is the only square in row 9 that can be <3>

R1C8 is the only square in row 1 that can be <3>

R5C3 is the only square in column 3 that can be <7>

R5C2 is the only square in row 5 that can be <3>

R2C3 is the only square in row 2 that can be <3>

R7C1 is the only square in column 1 that can be <7>

R4C2 is the only square in column 2 that can be <8>

R9C4 is the only square in column 4 that can be <8>

R3C8 is the only square in column 8 that can be <7>

Squares R1C7 and R1C9 in row 1 form a simple naked pair. These 2 squares both contain the 2 possibilities <12>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R1C1 - removing <12> from <1258> leaving <58>

R1C6 - removing <2> from <258> leaving <58>

Squares R1C7 and R1C9 in block 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <12>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R2C7 - removing <2> from <246> leaving <46>

R3C9 - removing <12> from <1246> leaving <46>

Intersection of row 4 with block 6. The values <69> 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 these values.

R6C8 - removing <69> from <2469> leaving <24>

Squares R5C8 and R6C8 in column 8 form a simple naked pair. These 2 squares both contain the 2 possibilities <24>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R8C8 - removing <4> from <469> leaving <69>

Squares R5C8 and R6C8 in block 6 form a simple naked pair. These 2 squares both contain the 2 possibilities <24>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R5C7 - removing <24> from <1248> leaving <18>

R5C9 - removing <24> from <12458> leaving <158>

R5C8 is the only square in row 5 that can be <4>
