If you say r4c7 is 2 then r2c7 = 8 and r2c3 = 6 and r8c3 = 1 and r8c7 = 7

If this were true there would be no digits left in <278> r1c7.

Therefore r4c7 < > 2

I used the chain: 7r7c8=r4c8-(7=8*)r5c9-(8=7)r5c4-r6c4=(7-5)r6c2=r6c9-(58*=7)r7c9 => r8c7 <> 7; stte.

Nice one Dongrave - it gave me a thought using your grid

There’s an ANP <578> at (a) and (h)

If true (5=78)r7c89 and r8c7 < > 7
If false (78=5)r7c89 then follow your chain in reverse (g to b) and r8c7 < > 7

A further refinement and c,d and e from the original grid can be replaced

(78=5)r7c89-r6c9=r6c2-(5=79)r4c23-(7)r4c8=r7c8-r8c7 :stte
