(84)r95c5 = (2568)b5p5369 => -8 r9c6; stte

--
The same seen in eleven's eyes: five digits in five cells, only 8 can be twice. Formally (perhaps):

Almost-DDS / Almost-MSNS: (2456[88])r59c5,r456c6 => -8 r9c6; stte

...or explicitly:

Alien 5x6-Fish: {59N5 456N6 \ 4c5 256b5 [8r9 8c6]} => -8 r9c6; stte

(84)r95c5 = (2568)b5p5369 => -8 r9c6; stte

Similar achievement using the ALS in r1278c4 with the bivalue cell in r9c5 r3c5<>8; stte (This is rated more difficult by Sukaku explainer as the largest cell in the ALS has 3 candidates)

Well spotted! It's perhaps closer to a classic "bent" VWXYZ-Wing:

(This is rated more difficult by Sukaku explainer as the largest cell in the ALS has 3 candidates)

Shouldn't mine actually be more difficult as its largest cells have four candidates? Or did I misunderstand?

I don't know about you but for me I always find the bigger cell easier to spot within an ALS because it guides you to the other cells of the ALS. I also find it easier to spot ALSs made up of bivalue cells. I'm in a position that the largest (biggest) & smallest (biggest) cells are easier for me to form an ALS around with the middle sized (biggest) cells being more difficult to see within an ALS

or, as a kraken:
Death blossom, stem (245)r5c5
(2)r5c5 - (2=568)r456c6
(4)r5c5 - (4=8)r9c5
(5)r5c5 - (5=268)r456c6

Hi tarek,

I don't know about you but for me I always find the bigger cell easier to spot within an ALS because it guides you to the other cells of the ALS ...

Well, at least in this case you might be right, if it's any indication which one I spotted more easily! However, there are probably many factors that determine how easy it is to spot a particular ALS, like for example how closely packed the ALS cells are. In yours they are spread pretty far from each other in the column, which makes it harder.

Also, my box-based ALS can be seen as two distinct parts (ALS 25+4 and AALS 68+25), like Cenoman wrote:

(8=4)r9c5 - (4=25)r5c56 - (2|5=68)r46c6 => -8 r9c6; ste

I think that's easier to spot than the full ALS at once, especially with coloring.
