Squares R3C1 and R3C9 in row 3, R4C1 and R4C5 in row 4 and R7C5 and R7C9 in row 7 form a Swordfish pattern on possibility <4>. All other instances of this possibility in columns 1, 5 and 9 can be removed.
   R1C1 - removing <4> from <1456> leaving <156>
   R1C9 - removing <4> from <1458> leaving <158>
   R5C5 - removing <4> from <246> leaving <26>
   R9C9 - removing <4> from <24> leaving <2>
R9C2 can only be <1>
Squares R4C9, R6C9, R4C5 and R6C5 form a Type-4 Unique Rectangle on <69>.
   R4C5 - removing <6> from <469> leaving <49>
   R6C5 - removing <6> from <269> leaving <29>
Intersection of block 5 with row 5. The value <6> 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 this value.
   R5C2 - removing <6> from <246> leaving <24>
Intersection of column 2 with block 1. The value <6> only appears in one or more of squares R1C2, R2C2 and R3C2 of column 2. These squares are the ones that intersect with block 1. Thus, the other (non-intersecting) squares of block 1 cannot contain this value.
   R1C1 - removing <6> from <156> leaving <15>
   R2C1 - removing <6> from <567> leaving <57>
Squares R1C1 (XY), R3C1 (XZ) and R1C8 (YZ) form an XY-Wing pattern on <4>. All squares that are buddies of both the XZ and YZ squares cannot be <4>.
