(Again, similar to my other post, I'd be surprised if it hadn't been spotted before.)

Just rows 1 to 6. Logic is that due to the unique loop on the 12s in rows 4-6, either r4c1 must be a 5, or r6c9 must be a 4 (or both). So one or both of r2c1 and r1c9 must be a 9. Hence the 9 in r1c2 can be eliminated.
