R1C6 can only be <5>

R9C4 can only be <4>

R6C6 can only be <1>

R1C5 is the only square in row 1 that can be <4>

R5C5 is the only square in row 5 that can be <2>

R5C2 is the only square in row 5 that can be <9>

R5C3 is the only square in row 5 that can be <3>

R1C2 is the only square in row 1 that can be <3>

R8C3 is the only square in column 3 that can be <4>

Squares R2C5 and R6C5 in column 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <69>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R4C5 - removing <6> from <368> leaving <38>

Squares R4C5 and R4C6 in row 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <38>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R4C8 - removing <8> from <4568> leaving <456>

Squares R1C3<27>, R2C3<57> and R3C2<25> in block 1 form a comprehensive naked triplet. These 3 squares can only contain the 3 possibilities <257>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R2C2 - removing <57> from <1567> leaving <16>

Intersection of column 2 with block 7. The values <78> only appears in one or more of squares R7C2, R8C2 and R9C2 of column 2. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain these values.

R9C3 - removing <7> from <257> leaving <25>

Squares R5C1 and R9C1 in column 1 and R5C9 and R9C9 in column 9 form a Simple X-Wing pattern on possibility <5>. All other instances of this possibility in rows 5 and 9 can be removed.

R9C2 - removing <5> from <12578> leaving <1278>

R9C3 - removing <5> from <25> leaving <2>

R5C7 - removing <5> from <1568> leaving <168>
