 Once again a wonderful puzzle, thanks hepa!
No chains, a setti consideration excluded one of two candidates on D6.

 one of the most elegant puzzles - looks unsolvable at the beginning but plenty of singles and settis, no chains needed this time

Like the others, too - a consideration similar to kris' start cleared H7 versus G89. Very nice!

 SPOILER

@tg: A little hint:

Looking at BH8 you'll see that upper part of / is low.

7 in 18GHj and J1H2G3: This is not a real starfish just almost a starfish. But you can still deduce J1=7. (Otherwise 7 in 1GH, 8GH, and H2G3.) The second almost fish is bigger.

 It is surprising how the puzzle collapses after the two eliminations mentioned by BP and one setti.

 For all who cannot solve with settis only: count all 8 you need, there is one row without 8

 Yes Rudik, but with this firework of settis...I liked to set the focus on 8 and later 9. But this became obvious for me after solving.

 Tough, but I liked it. B-setties are as usual very important and this time box 7, 8 and 9. I realized that G3=6789 and later J9=12 not working in row J in combination with setties.

 Thanks for this nice puzzle and for Cosmanita's observation. One of the cells G3/H2 has to be 4, so no 9 in the diagonal /

Not as hard as the x or last week's, but took a lot of careful work. Very clever observation, Neunmalneun (and a good handle, too).
