It may be considered "overkill", but I just could not resist posting this unusual "almost" Sue de Coq where only the "e" component made a deletion.

ASdC(13567)r4c789 with (35=1)r4c2
[SdC(13567)r4c789 ab=(35)r4c2, cd=(17)r5c9, e=6 => r4c5,r6c8<>6] = [1r4c2-(1=8=7)r2c26-(7=6=2)r7c61-(2=7=6)r6c15 => r4c5,r6c8<>6] => r4c5,r6c8<>6

.. "almost" Sue de Coq ...

The next thing i am looking forward to is an almost Exocet, or did i miss one ?

I am not very firm about Sue de Coq's, but in this case you dont need one. Without the 1 in r4c2, it is locked in box 6, which gives a 7 in r5c9 and r4c5, which also locks 6 in row 4 of box 6.

Verbalized: (Sdc)=(1)r4c2-(x=y chain)

I must be as perverted as you, Ted. Not only do I see that, but I like it. I could see bumping into that while chasing that potential xy-chain around the grid.

There's also a way to get into that xy-chain starting with (6)r4c789=(6)r6c8, using (16)r2c8...but that just wouldn't be as interesting
