Squares R5C2 and R6C1 in block 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <14>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R4C1 - removing <1> from <136> leaving <36>

R5C1 - removing <14> from <1346> leaving <36>

Squares R4C1 and R5C1 in column 1 form a simple naked pair. These 2 squares both contain the 2 possibilities <36>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R8C1 - removing <3> from <349> leaving <49>

Intersection of row 4 with block 5. The value <1> only appears in one or more of squares R4C4, R4C5 and R4C6 of row 4. These squares are the ones that intersect with block 5. Thus, the other (non-intersecting) squares of block 5 cannot contain this value.

R5C4 - removing <1> from <1249> leaving <249>

R5C5 - removing <1> from <123489> leaving <23489>

R5C6 - removing <1> from <13489> leaving <3489>

R6C5 - removing <1> from <1247> leaving <247>

R6C6 - removing <1> from <147> leaving <47>

Intersection of row 7 with block 8. The values <14> only appears in one or more of squares R7C4, R7C5 and R7C6 of row 7. These squares are the ones that intersect with block 8. Thus, the other (non-intersecting) squares of block 8 cannot contain these values.

R8C6 - removing <4> from <3489> leaving <389>

R9C4 - removing <4> from <249> leaving <29>

R9C5 - removing <4> from <23489> leaving <2389>
