Squares R2C3 and R3C3 in column 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <26>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R7C3 - removing <6> from <156> leaving <15>

R8C3 - removing <6> from <156> leaving <15>

Squares R2C3 and R3C3 in block 1 form a simple naked pair. These 2 squares both contain the 2 possibilities <26>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R2C2 - removing <6> from <3467> leaving <347>

Intersection of row 7 with block 8. The value <4> 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 this value.

R9C4 - removing <4> from <134> leaving <13>

R9C6 - removing <4> from <14568> leaving <1568>

Squares R1C6 and R1C9 in row 1 and R9C6 and R9C9 in row 9 form a Simple X-Wing pattern on possibility <5>. All other instances of this possibility in columns 6 and 9 can be removed.

R3C6 - removing <5> from <58> leaving <8>

R7C6 - removing <5> from <1456> leaving <146>

R8C6 - removing <5> from <15689> leaving <1689>

R9C8 is the only square in row 9 that can be <8>

R8C5 is the only square in row 8 that can be <8>

R8C4 is the only square in row 8 that can be <7>

R1C2 is the only square in row 1 that can be <7>

R2C5 is the only square in row 2 that can be <7>

R8C6 is the only square in row 8 that can be <9>

Squares R8C2 and R8C8 in row 8 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 row.

R8C7 - removing <36> from <1356> leaving <15>

Squares R8C7 and R9C9 in block 9 form a simple naked pair. These 2 squares both contain the 2 possibilities <15>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R7C7 - removing <15> from <1356> leaving <36>

Squares R7C5 (XY), R9C4 (XZ) and R7C3 (YZ) form an XY-Wing pattern on <1>. All squares that are buddies of both the XZ and YZ squares cannot be <1>.
