checked what if column1 does not contain 8 and implication on row HJ, CE row E, high low on column 6 (wrong choice quickly leads to conflict) - really nice puzzle, took me 35 min, but how to do in 7 min?

Had to restart, but then it ran smoothly throug. No need for chains.

very nice puzzle, i like the level of difficulty
for me CE enough, in the end a little Setti 7 to solve
 

by: Jan

 I quite agree!

IMO, there are three steps required: In a row, a pair of digits can only go in one compartment, there is a large gap and finally an x-wing.
 

by: Jens

 I think, that pair of digits followed by one x-wing might be enough.
 

by: Q

Agreed. The solver couldn't put the pair in, nor did it see the X-wing. Once they were done, it solved it.

 A real beauty! Starting with VCE in Box9 it develops smoothly with settis and b-settis. Thanks a lot!
 

by: Martinus

 Like hel. Thanks!
 

by: Loser

 THX for the set
 

by: optimator

 I needed a short chain near the end
 

by: kmr

 Very nice puzzle with a perfect level of difficulty. Relaxing. Thanks!!!
 

by: BP

 Like Hel. Nice.
 

by: Susan

 Very nice one, start in box9 like Hel and then easy going.
 

by: ThomasF

nice, not easy but solves without chains

by: Martinus

 Quite hard. For me the key was an interdependency between column 3 and box 1. Thanks, kst!
 

by: optimator

 a careful look at B3 solved it for me
 

by: BP

 Excellent chain free challenge. We probably solved it like Martinus.
 

by: kmr

Wow. Hard work, but doable in the end. Thanks!

by: Martinus

 Did it, but needs some CE, settis and chains in the end. Thanks, kst!
 

by: jgrab

 Hard work, but good and logical development. No chains. Settis; large gap.
 

by: optimator

 It starts quickly with 2 wings, then with this shape I use chains on E5 to eliminate 2 of the 3 candidates. Thanks kst!
 

by: BP

 Standard tools + one very skewed xwing. Nice!
 

by: Auwei

Like BP; consider J7: wrong assumption leads to error in col 1

by: E.H.

 Needed a chain in row G.
 

by: Cosmanita

 Nice, but I also needed chains. Mine started in G9 and in J7. The contradiction happened in column 7,8,9 and row J.
 

by: BP

 Great challenge, needed all standard tools plus an UR (6 in F56, otherwise 56HJ=67).

We are really going to miss kst's wonderful puzzles. Next week we are posting his last set.
 

by: Martinus

 Did it without chains. Two fishes and one UR, plus settis. Thanks, kst!
 

by: optimator

 like Cosmanita
 

by: Frank

 Definitely possible without chains.
Brilliant!
 

by: E.H.

 Martinus and BP, you are right, no chain necessary.
 

by: Susan

 No chain, just settis and CE
 

by: kmr

Like Martinus. Very nice puzzle.
