I don't see what can be Wrong! with asking a question. Let me put it another way. If r3c6 contains only the two candidates <35>, why on earth would you write (3-5)r3c6?
The Wrong! was in re ... |

Help me here:
(3=5)r3c6 says r3c6 is a bivalue cell. Right?
(3-5)r3c6 says what??
Wrong!
(3=5)r3c6 says there's a strong inference between the candidate <3> and the candidate <5& ... |

I don't think that last sentence is very accurate.
It was a failed attempt at "whimsey". Someone use to repeat the conclusion of discontinuous loops ... and I thought it was you. Sorry! |

Here's my "working definition" of strong inference and weak inference.
Strong Inference: When you have two possible outcomes and you assume that one outcome isn't true, then you must ... |

I found Angus Johnson's post from 2005 here. I had forgotten his "Type 3" was for simple coloring, which we don't have in this example. Perhaps it is X-coloring, but I can't check that out r ... |

I also used the DP 49 in boxes 258. Either r1c4 or r6c6=6 or r9c6=8. Common outcome; r4c6=6.
r6c6 = 6 implies r4c6 =6? How can that be? They are in the same column.
If r6c6=6 is false, then it's ... |
