Many thanks, Ron, for the helpful feedback and suggestions. I had a feeling there were no “simple” answers to those two questions. Your reference to Obi-Wahn’s posts regarding finned fish is very interesting, and I plan to take a closer look at those threads. I also found your example of the ER patt...

Mystery solved! Thanks for the link to udosuk's writeup. It's interesting...sometime back I ran across your post here and saved a hardcopy for my "wings" folder because it seemed like such a easy pattern to search for. It didn't seem to have a name, though, and I just couldn't imagine Y-no...

Hi Para,
Could you please clarify some nomenclature? I'm confused about exactly what a "y-wing" is. Sudopedia redirects to xy-wing, and Andrew Stuart's Sudoku Solver site says "aka xy-wing." But you refer separately to both.
TIA!

This exercise was undertaken to see if, in addition to the standard “basics” toolbox of solving methods, it might be possible to manually solve a difficult puzzle using only simple Alternating Inference Chains (AIC). And, just for the sake of argument, allowing no other solving techniques, such as p...

Thanks again...good explanation! I hadn't seen your threads in the other forum. In Ron's jargon, (3)r4c7 must be the "spoiler" digit in the "almost" pattern, and in this case is more like the fin in a finned fish because the spoiler can see the victim cell. I'm guessing the AIC (...

The cells (5,5), (4,6), (4,7), (4,8) could be viewed as an almost xy-chain ... Thanks, rep'nA, for the feedback! I've learned just enough about "almost" structures from some of Ron Moore's postings to be almost dangerous :) , but I'm not sure about an almost xy-chain. Can you show how tha...

I have similar difficulties with most methods used to find fish patterns. However, not long ago I ran across Arcilla’s article in the other forum entitled, "a new (?) view of fish (naked or hidden)" http://www.sudoku.com/boards/viewtopic.php?t=5017. His technique is easy to apply and seems...

Really learning a lot on this thread... (6): r1c3 = r4c3 - r4c4 = r2c4 - r2c7 = r1c79 - r1c3 => AIC loop... So, isn't this "Fishy Cycle" also a Franken swordfish? Base: c3, c4, b3 Cover: r1, r2, r4 If so, it would appear to provide all six of the AIC loop's original eliminations without an...

Maybe I can change the printable versions to PDF format. I will look into this shortly. Actually, 98% of all forum postings will print just fine right out of a browser. The problem is only with that 2% that exhibits this pesky truncation problem on the right-hand side. Sure would be nice to know wh...

Thanks for relaying your experience with Firefox.

Very interesting and strange...I tried that site you mentioned (http://sudocue.net/cluelessguide.php), and it seems to not truncate when I view it on my Windows 2000 IE "Print Preview" option.

Not sure where to go from here.

Cannot seem to figure this one out: Certain posts, when examined using my Windows 2000 IE "Print Preview" option, show the pages truncated on the right-hand side (and they print that way, too). E.g., when I "Print Preview" enxio27's recent post on "Specials page", the p...

Got it...thanks!

MJ,

One quick follow-up question on your "trick"...
Does “stand-alone” mean naked only, or can a successful cyclic path also indicate a possible hidden fish?
