A short SI: If AB9 and A89=8/9 then A6=7, B6=8, B9=9, reducing A8 to 5/9 wich is a large gap, eliminates 5 from B8 and leaves a single 5 in B2.

Although I need a chain towards the end, I like this puzzle. And maybe, the community will again find a better solution than mine.

my first apprach: an easy chain to define G3 at the beginning and a UR.
I shall try again later.

@c: G3 can be solved via Setti.

the post of 04:10 was mine. Sorry.
I had a new trial:
The only possibility to avoid a UR in E9 is A9= x and B9 = y.
This solves this nice puzzle with two x-wings. No chain.

Nice puzzle, no chain needed. (UR, setti, wings.) Thanks!

@Christoph,

I wasn't able to solve AB9 to avoid a UR.

I could narrow E9 to 1 or 9 - I eliminated the 2 by reducing HJ9 to 123.
But I am still left with two alternatives:
- if AB9=89 - it would be 1
- if HJ9=12 - it would be 9

I needed a small chain to settle AB9.

same for me. I liked it very much but needed a chain to decide on column 9.

@Ben, @kmr:
my way was : H9 cannot be 4 (leaves E9=12 , which is not unique).
Thus my conclusion was AB9 must be 43.
But I realize now that it could also have been 89.
Thus my way is based on a lucky failure. Sorry about that.

I could clear G3 with setti 2. After that I could exclude 5 from B9, as this would lead to 5s in column 8&9 and a setti violation. But that still left me with 3/8/9 in B9 and a chain. Still curious if there is a chainless way.
Thank you, hoke!

There are further eliminations, but they do not solve the puzzle: 2 in H56 because of Xwing 2, 3 in CD2 because of UR in AB12, 1 in B2 because of contradiction in CD2, 3 in B3 because of ywing BC23.

Thanx morl. Very tricky. Two UR preventions and a small SI needed.

For me this was very demanding. I had to use the X-Argument until the end. I needed one UR, wings and some Settis.

A wonderful puzzle, as the one of home.

I don't like auto correction, but it often helps. The second time that I called Hone home...sorry for that.

Thanks,hone!

It's how I like it.

very nice, hone. lots of various wings, besides standard tools.
Thanks.

Thank you, hone. I needed very careful work to see the tools needed to solve.

Thank you, hone!
As my wing-spotting abilities are rather poor, this was tough work for me: But finally it solved!

I used a UR, and at the end a SI to find B4 and to solve this nice puzzle.

yes, nice puzzle. I didn't need UR, just wings and setti, and at the end a micro chain (wrong number on A1 immediately leads to a contradiction on D1 or D2)

very clever Kolumbus,didnt see that; stared minutes on the board without finding an easy way out for the last few cells

A mini XY-Chain D2-A2-A7-B7 solves B2 and the puzzle. Nice.

To finish solving I notice that 9 is one of the sure digits in row A (9 must appear in A12 or A789). Thus we got an X wing with 9 on rows A and C which solve remaining cells.
