Yet again preempted by a couple of minutes, will try again later!
How about:
Code: Select all
(1)r7c7 = r8c7 - (1=7)r8c1 - r8c9 = (7-2)r9c9 = (2-1)r9c1 = r7c3 => -1 r7c456; stte

           r8c13

Clement, I don't see that r8c3=4 solves the puzzle.

O.K
The initial assumption 17 in r8c13 eliminates the 7 in r8c9. However, the chain shows it must be 7 which eliminates it in r8c13. I am sorry for not mentioning that in my conclusion.

Hi, Clement. I understood your chain. However, assigning 4 to r8c3 doesn't seem to reduce the puzzle to singles, or even to basics.
