(7=48)r45c9 - (8)r5c1 = (8-9)r6c1 = r6c3 - r8c3 = r8c9 - (9=7)r9c8 => - 7r4c8; btte |

Not as elegant:
Code: | Remove Put back
|| ||
\/ \/
(9)r3c8=r9c8-r8c9=r8c3-r6c3=(9-8)r6c1=r6c8-(8=9)r3c8
So r3c8 = 9 |

| We said that r3c8 is not 9. The chain proves us wrong! It is 9. It is elegant, why not. |

I guess (in my mind at least) that it is down to aesthetics, Clement. My chain is a contradiction loop, has more steps and it ends where it started.
I found your chain and its conclusion to be "less agricultural". |
