  	  | Code: |  	  | +--------------+---------------+---------------+ |  39  4   12  | 5    19   8   | 6    23   7   |
 |  39  5   12  | 6    4    7   | 8    23   19  |
 |  78  78  6   | 3    19   2   | 19   4    5   |
 +--------------+---------------+---------------+
 |  5   6   4   | 1278 278  3   | 127  9    128 |
 | a78  3   9   | 12   6    4   | 5    7-8  12  |
 |  1   2  b78  | 9    78   5   | 4    6    3   |
 +--------------+---------------+---------------+
 |  4   1  c578 | 278  3    9   | 27  f578  6   |
 |  6  d78  3   | 4    2578 1   | 279 e578 e289 |
 |  2   9  c578 | 78   578  6   | 3    1    4   |
 +--------------+---------------+---------------+

 Then I used the chain 8r5c1=r6c3-r79c3=r8c2-r8c89=r7c8 => r5c8 <> 8; stte.

				| I used a finned xwing to remove 7&8 from r8c5. Remote pairs also works. A x-chain to remove 2 from r8c9
 A xyz wing to remove 8 from r8c9

				| Nice puzzle Immpy! 
 I started off seeing that if r4c5=8, r6c5=7 would give <12> UR in r45c49
 
 But then if r4c4=8,  r6c5=7 you can follow the <78> pairs around the grid to get r6c5=8, this left me a <127> triple in box 5
 
 So remove <7> from r6c5 to solve
