Naked Pair 2/6 on cells {D5|E5} means
- 6 can be removed from D6
- 6 can be removed from E4
- 6 can be removed from E6

Naked Pair 2/9 on cells {F8|F9} means
- 2/9 can be removed from D9
- 2/9 can be removed from E7
- 2/9 can be removed from E8

Hidden Pair 3/5 in Row H, on cells {H2|H3}
- removes 1/8 from H2
- removes 1/7/8 from H3

Naked Pair 3/5 on cells {H2|H3} means
- 5 can be removed from J2
- 5 can be removed from J3

Pair: between Box 2 and Row C:
- 6 can be removed from C8
- 6 can be removed from C9

Pair: between Box 7 and Col 1:
- 7 can be removed from A1
- 7 can be removed from B1

Pair: between Box 7 and Row J:
- 8 can be removed from J7
- 8 can be removed from J9

(RULE 6): Both candidates 4/9 in cell B1 (which are not coloured) can see the same colour elsewhere. If that colour were true it would leave B1 empty. So all candidates of that colour can be removed.

Naked Pair 1/2 on cells {C2|C9} means
- 2 can be removed from C3
- 2 can be removed from C8

If +1[G7] then -1[A7] forcing +1[A1] which removes all 1s from Box 7, so G7 cannot be 1

If +2[A7] then -2[A3] forcing +2[J3] which removes all 2s from Box 9, so A7 cannot be 2

Naked Pair 1/9 on cells {A1|A7} means
- 9 can be removed from A8

Line/Box Reduction: 2s in box 9 remove the following in the same box:
- 2 can be removed from J9

Y-Wing pattern. Hinge: C9 (1/2), wings A7 F9, therefore
- 9 can be removed from B9

X-CYCLE on 1 (Discontinuous Alternating Nice Loop, length 8):
+1[J7]-1[J4]+1[G4]-1[G2]+1[C2]-1[A1]+1[A7]-1[J7]
- Contradiction: When J7 is set to 1 the chain implies it cannot be 1 - it can be removed

(RULE 1): Two candidates in J7 have the same color - all yellow coloured candidates can be removed
