Naked Pair 5/7 on cells {D1|E1} means
- 5 can be removed from D2
- 5 can be removed from E2

Naked Pair 2/6 on cells {D2|D6} means
- 2 can be removed from D5
- 2 can be removed from D9

Pair: between Box 9 and Col 8:
- 3 can be removed from E8
- 3 can be removed from F8

Line/Box Reduction: 5s in box 6 remove the following in the same box:
- 5 can be removed from E7
- 5 can be removed from E8

XYZ-Wing pattern. Hinge: E4 (1/4/8), wings E7 F4, therefore
- 4 can be removed from E5

Type 2b: removing 2 at E2 because of DE26 and one strong link on 6 between D6 and E6

If B2 is not 4 then all 1s in Col 7 are removed so B2 must be 4

Last candidate 4 in B2 changed to solution

2 cannot be set in the yellow cells {B7,B8,B9} and with the Remote Pair in A6 and C2 it means:
- 9 can be removed from A3
- 9 can be removed from C5

9 in C2 is last in row

2 in D2 is last in column
9 in J3 is last in row/column/box

length=5, chain ends: A4 and F5
This proves 4 is the solution at one or possibly both ends of the chain
