*want*to discuss a solution from doing so. So, let's see how this forum works for this!

After relatively straightforward (BX) eliminations (including Setti 4 for col 9, and realizing that box 2 contains 2 and 8, so col 6 misses 19), we arrive at a board like this: Here's where the fun starts

* Setti 3: if box 1 contains 3, then in A23; eliminate from rest of box

* 2fish 7 /\: H4!=7

* 3-fish 9 E/\

* D5!=9 (B power)

* Setti 9: if A8=9, C3=B5=9, A5=7 --> A2!=7, box +col 1 contain 7

* CE: B5!=6 (if B5!=9, A8=7-->B8=6 via J8)

* CE: A5!=6 (C3=7 via \, but C3=9 via Setti 9 after E4=6,E2=9)

* Setti 9: B5!=5, C3!=7

* An interesting "B-based wing" on 5 made of H34, AG5, where the base cells H4,G5 are coupled via B power and the link between AG5 is through Setti 5: A3!=5

* HC: B7!=7 (A5=5-->B7=9, A5=7-->B7=1 via C2; alternatively conflict loop B7=7-->A8=7 via C8, C2, A2, A5)

Funny that most useful tricks should revolve around 9 of all digits. I don't see that a lot.

I'm curious if anyone found an easier solution
