Hidden Pair 3/8 in Box 1, on cells {B2|B3}
- removes 2/6 from B2
- removes 2 from B3

Naked Pair 3/8 on cells {B2|B3} means
- 3 can be removed from B8

Pair: between Box 3 and Row A:
- 9 can be removed from A1

If +6[E6] then -6[E2] forcing +6[C2] which removes all 6s from box 2, so E6 cannot be 6

XYZ-Wing pattern. Hinge: D2 (2/3/8), wings B2 D1, therefore
- 8 can be removed from E2

(RULE 2): Two 4s in a single unit (in Box 6) have the same color in cells D9 F8 - all yellow coloured candidates can be removed

Hidden Pair 6/9 in Col 2, on cells {C2|E2}
- removes 2 from C2
- removes 3 from E2

BUG+1 found in A8, 2 must be the solution

All other incomplete cells contain two candidates apart from A8. Other candidates in A8 would create two or more solutions so they can be removed.
