I didn't spot the XYZ, and could only find a two-stepper.

X Wing on 4 in columns 6 & 7 turns Marty's XYZ wing into an XY wing, removing 4 from r6c7, then stte.

I had to use 2 'standard' moves. My first move (which Clement said solves it!) was the 16-7 XY Wing with pivot at r9c9 and then a 19-6 XY Wing with pivot at r9c1 which solved it! I have to go back a ...

Hi guys,

The owner says he's out of squigglies. He didn't say so specifically, but reading between the lines I think there won't be more.

Sorry,
Marty

Shame, I preferred those to classics.

Also a 2-stepper, the X wing on 3s also reveals a W-Wing on 27 (boxes 4 & 7), R8C3 <>2, then stte.

S-Wing? What's one of them, then?

The X-Wing also opens another XY-Wing 4-89, pivot r3c8, making r2c4<>4, which also STTE.

I don't see the XY Wing, though I may not quite have finished basics.

Look closely at r2.

Thank you Marty. Very Happy

There is also a W Wing 17, boxes 6 & 8, strong link on 7 in box 5, meaning R9C8 <>1.

There's a one-stepper.

W-Wing 15, pincers R4C9 and R5C5, strong link on 5 in column 3, sets R4C4 <>1 (and R4C5 as well, but that's fairly irrelevant). This STTE.
