R4C2 can only be <2>
R6C2 can only be <6>
R2C7 is the only square in row 2 that can be <9>
R4C8 is the only square in row 4 that can be <9>
R5C2 is the only square in row 5 that can be <7>
R3C3 is the only square in row 3 that can be <7>
R5C1 is the only square in row 5 that can be <1>
R7C4 is the only square in row 7 that can be <3>
R7C7 is the only square in row 7 that can be <7>
R9C5 is the only square in row 9 that can be <7>
R7C1 is the only square in column 1 that can be <8>
R7C8 is the only square in column 8 that can be <6>
R3C9 is the only square in column 9 that can be <3>
Squares R6C3 and R6C8 in row 6 form a simple locked pair. These 2 squares both contain the 2 possibilities <58>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.
   R6C5 - removing <8> from <238> leaving <23>
   R6C7 - removing <58> from <2358> leaving <23>
Squares R4C3 and R6C3 in column 3 form a simple locked pair. These 2 squares both contain the 2 possibilities <58>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.
   R1C3 - removing <5> from <1456> leaving <146>
   R2C3 - removing <5> from <1245> leaving <124>
Intersection of row 2 with block 2. The value <5> only appears in one or more of squares R2C4, R2C5 and R2C6 of row 2. These squares are the ones that intersect with block 2. Thus, the other (non-intersecting) squares of block 2 cannot contain this value.
   R3C4 - removing <5> from <256> leaving <26>
   R3C6 - removing <5> from <1258> leaving <128>
Intersection of row 9 with block 7. The value <6> only appears in one or more of squares R9C1, R9C2 and R9C3 of row 9. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain this value.
   R8C3 - removing <6> from <12469> leaving <1249>
Intersection of block 5 with row 5. The values <59> only appears in one or more of squares R5C4, R5C5 and R5C6 of block 5. These squares are the ones that intersect with row 5. Thus, the other (non-intersecting) squares of row 5 cannot contain these values.
   R5C8 - removing <5> from <458> leaving <48>
   R5C9 - removing <5> from <245> leaving <24>
Squares R4C5<38>, R5C5<28> and R6C5<23> in column 5 form a comprehensive locked triplet. These 3 squares can only contain the 3 possibilities <238>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.
   R1C5 - removing <8> from <1468> leaving <146>
   R2C5 - removing <2> from <124> leaving <14>
   R8C5 - removing <2> from <126> leaving <16>
