Pair: between Box 6 and Row F:
- 2 can be removed from F3

Pair: between Box 2 and Row B:
- 4 can be removed from B3

Pair: between Box 8 and Row H:
- 4 can be removed from H1

Naked Pair 6/8 on cells {E1|H1} means
- 6/8 can be removed from C1
- 8 can be removed from G1

Triple: between Box 2 and Row A:
- 6 can be removed from A2

Pair: between Box 6 and Row F:
- 9 can be removed from F6

Some solution combinations in the two gray cells would empty at least one of the coloured cells. Removing those combinations create eliminations in the gray cells.
Pair A7 / B5 reduced from 1/3/8->1/3/8 and 3/4/8/9->3/4/8
- Pair 1/9 found in ALS {B9}
- Combinations of 3/6/8/9 found in ALS {A4,A5,A6}

Pair: between Box 2 and Row A:
- 9 can be removed from A2

XYZ-Wing pattern. Hinge: B2 (1/8/9), wings A2 B9, therefore
- 1 can be removed from B3

Hidden Pair 1/9 in Row B, on cells {B2|B9}
- removes 8 from B2

Pair: between Box 1 and Col 2:
- 1 can be removed from D2
- 1 can be removed from E2

(RULE 4): Uncoloured candidate 8 in G2 can see two different coloured candidates of 8 elsewhere.

Y-Wing pattern. Hinge: G8 (2/8), wings C8 G2, therefore
- 9 can be removed from C2

length=7, chain ends: B3 and D5
This proves 3 is the solution at one or possibly both ends of the chain
-3[B3]+8[B3]-8[A2]+1[A2]-1[B2]+9[B2]-9[G2]+2[G2]-2[D2]+5[D2]-5[D6]+9[D6]-9[D5]+3[D5]
- 3 can be removed from B5

Hidden Pair 3/9 in Col 5, on cells {A5|D5}
- removes 6/8 from A5

Line/Box Reduction: 6s in box 8 remove the following in the same box:
- 6 can be removed from H6
- 6 can be removed from J4
- 6 can be removed from J6

length=7. This XY-Chain is continuous and one value in each cell must be the solution, so all off-chain candidates can be removed
-2[G2]+9[G2]-9[G1]+4[G1]-4[C1]+9[C1]-9[B2]+1[B2]-1[B9]+9[B9]-9[C8]+8[C8]-8[G8]+2[G8]
- 2 can be removed from G3

(RULE 2): Two 1s in a single unit (in Row F) have the same color in cells F3 F7 - all yellow coloured candidates can be removed
