You need to follow the <5> around to get -5 in r9c1 to solve

If a=5, b=5, c=5, d=5, (*=not 5)

Nice solution Tom! The slightly modified chain with pincers on both ends would be 5r1c1 = r1c6 - r3c5 = r5c5 - r5c9 = r9c9 => r9c1 <> 5; stte.

looks like a finned Swordfish (5) c159\r359 with fin=r1c1 → r3c23 ≠ 5 → (5) b1\c1 → r9c1 ≠ 5
