R2C1 is the only square in row 2 that can be <2>

R6C3 is the only square in row 6 that can be <7>

R8C7 is the only square in row 8 that can be <2>

R8C3 is the only square in row 8 that can be <6>

R9C1 is the only square in row 9 that can be <9>

R7C3 is the only square in column 3 that can be <5>

R4C7 is the only square in column 7 that can be <5>

Intersection of row 2 with block 3. The values <167> only appears in one or more of squares R2C7, R2C8 and R2C9 of row 2. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain these values.

R1C9 - removing <7> from <3478> leaving <348>

R3C9 - removing <17> from <13478> leaving <348>

Squares R1C9, R3C9 and R7C9 in column 9 form a simple locked triplet. These 3 squares all contain the 3 possibilities <348>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C9 - removing <34> from <13467> leaving <167>

R5C9 - removing <4> from <146> leaving <16>

R8C9 - removing <38> from <3578> leaving <57>

R9C9 - removing <38> from <3578> leaving <57>

Squares R8C9 and R9C9 in column 9 form a simple locked 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 column.
