R8C6 can only be <5>

R3C5 is the only square in row 3 that can be <5>

R5C4 is the only square in row 5 that can be <8>

R5C5 is the only square in row 5 that can be <6>

R7C2 is the only square in row 7 that can be <8>

R8C1 is the only square in row 8 that can be <1>

R1C9 is the only square in row 1 that can be <1>

R8C9 is the only square in row 8 that can be <8>

R5C1 is the only square in column 1 that can be <9>

R5C3 is the only square in block 4 that can be <4>

Squares R8C7 and R8C8 in block 9 form a simple naked pair. These 2 squares both contain the 2 possibilities <67>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R7C7 - removing <67> from <45679> leaving <459>

R7C8 - removing <67> from <467> leaving <4>

R9C5 is the only square in row 9 that can be <4>

Intersection of row 2 with block 1. The values <12> only appears in one or more of squares R2C1, R2C2 and R2C3 of row 2. These squares are the ones that intersect with block 1. Thus, the other (non-intersecting) squares of block 1 cannot contain these values.

R3C2 - removing <2> from <23> leaving <3>

R3C3 - removing <2> from <2367> leaving <367>

Intersection of row 6 with block 4. The values <25> only appears in one or more of squares R6C1, R6C2 and R6C3 of row 6. These squares are the ones that intersect with block 4. Thus, the other (non-intersecting) squares of block 4 cannot contain these values.

R5C2 - removing <25> from <125> leaving <1>

R2C2 can only be <2>

R2C1 can only be <4>

R6C2 can only be <5>

R1C1 can only be <6>

R3C3 can only be <7>

R2C3 can only be <1>

R6C5 is the only square in row 6 that can be <1>

R4C8 is the only square in row 4 that can be <1>

Squares R3C6 and R3C9 in row 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <49>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R3C7 - removing <49> from <2469> leaving <26>

R7C7 is the only square in column 7 that can be <9>

R7C5 can only be <7>
