Same first move for me as Marty but my second move was XY-Wing 46-2 hinged in r9c6=> -2r7c9. Marty's second move did not make sense to me but it won't be the first time.

Hi,

I found this very hard to do but my solution only seems to be of the hard variety. I am sure someone else will correct my error in basics or logic.

Found the same as Hugh and had a lot of fun as usual. I see that Hugh's basics are not quite complete, he did not eliminate the 1 from r5c9 that is key to the solution we both found. Like Hugh I belie ...

Thanks Hugh for explaining the box lines on 3's. It is one of my weaknesses not following through on all the basics once I have found an elimination. Even my x wing on 3's would have been enough to di ...

You both did better then me, to be honest I still don't see Clement's solution after x wings on 5. I needed the x wing on 5's then x wing on 3's (r68) then xyz wing 679 (pivot r3c8).

I was totally ...

I gave up on this hard after 45 minutes and used the hint button to discover the hidden pair 12 in column 7 rows 2 and 7 leading to r7c9=9 and the rest of solution fell out. Thanks George and Marty fo ...

It took me the same 3 steps as Hugh in the same order and it was totally enjoyable.

XY-wing 45-6 pivoted in r6c9; r4c1<>6, maybe stte but not sure yet

Thanks arkietech, if I learn the terminology and apply it I am hoping to get better. I also think your username is very clever and hope to some day understand your solution posts. You seem to be at a ...

I saw the 136 XYZ-wing pivoted r6c5; r6c6<>3 first. Strange because I usually see XY wings way before XYZ wings. Can someone explain what does the stte in Clements solution mean ?

Thanks,

Another one step but also equally dubious solution:

type 1 UR on 26 in boxes 6 and 9

I hope I did the fancy hidden solution correctly, thank you Hugh for your great posts.

XY-Wing 14-19-49 pivoted in r7c9 solved it for me. Since I don't see any solutions yet I registered and posted this one.

I really appreciate this forum and I guess I was finally moved enough to ma ...
