R6C7 can only be <4>

R8C2 is the only square in column 2 that can be <5>

R3C7 is the only square in column 7 that can be <6>

R6C8 is the only square in column 8 that can be <3>

R6C5 can only be <6>

R4C5 can only be <4>

R4C8 is the only square in column 8 that can be <7>

R5C9 is the only square in block 6 that can be <1>

Squares R3C3 and R3C4 in row 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <47>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R3C6 - removing <7> from <279> leaving <29>

Squares R7C3 and R7C4 in row 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <16>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R7C5 - removing <1> from <159> leaving <59>

Squares R6C2 and R9C2 in column 2 form a simple naked pair. These 2 squares both contain the 2 possibilities <17>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C2 - removing <7> from <3679> leaving <369>

Squares R3C5 and R3C6 in block 2 form a simple naked pair. These 2 squares both contain the 2 possibilities <29>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R1C5 - removing <9> from <139> leaving <13>

R2C6 - removing <9> from <379> leaving <37>

Squares R6C2 and R6C3 in block 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <17>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R5C1 - removing <7> from <479> leaving <49>

R5C3 - removing <7> from <478> leaving <48>

Squares R1C1 and R5C1 in column 1 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 column.

R2C1 - removing <49> from <4679> leaving <67>

Squares R8C8, R8C9, R1C8 and R1C9 form a Type-3 Unique Rectangle on <48>. Upon close inspection, it is clear that:

(R1C8 or R1C9)<19>, R1C5<13> and R1C2<39> form a naked triplet on <139> in row 1. No other squares in the row can contain these possibilities

R1C1 - removing <9> from <49> leaving <4>
