Thanks, cgordon!
Actually, the "code" sudoku that I presented before my little one-line solution was not the real board that I was faced with! I neglected to copy what I was actually f ... |

It seemed like it took years to find the (237) xy-wing, but, that's what broke it open! |

I'm looking all around for the 245 xy-wing - usually, I see 'em pretty fast...however, I can't find it here (at least, where I can actually eliminate a common "claw" number). Where is the d ... |

The next steps that I see are the 2 separate Unique Rectangles:
The '<28> in rows 5 and 6, and the <69> in columns 2 and 3...after that, I believe that you're home free.
Still, I sure ... |

Your other "puzzle solver" is unknown to me. Try to go through the steps and prove how your elimination works. Which '6' is eliminated? From what cell? Why? There is a huge chance that t ... |

I can't see an XYZ-Wing based in r7c1. It appears that you're treating that cell as if were 26 and creating an XY-Wing. The essence of an XYZ-Wing is that candidates are eliminated that can see all ... |

Isn't the XYZ-Wing from <269> in R7C1, eliminating the <9> in R3C7 legitimate? I haven't heard anyone mention that; this is what I used to solve it (I must've been lucky, I guess!!)

No problem, Florida Bob,
The '7's in Rows 2 and 8, as well as along Column 1 are strong pairs (one or the other cell along those paths HAS to be a '7').
Therefore, in Column 9, the 7 HAS to be ... |

...UR 25 r46c19 (in order to avoid the deadly pattern, r46c1 must contain 9) solves r1c1=4 and r5c2=9.
That's what did it for me, too! |
