Nr 2. This appeared when searching for a knot that ...
Appeared AND was recognized as worthy --captured!
In contrast ::
My
"Quick8" EK is something that I tied LONG ago
--heck, maybe even making an image of the state--,
but not until decades later did I realize that I could
STOP at that point (!), no need to U-fold that tucked
RELeg Tail back into the Fig.8 base for security!
It (Q8) was smack before me yet un*seen*.
((Q8 = F8 base, RELeg return through 8's U-turn
as for common Fig8 EK, then simply reeved out
through other "loop" of F8 going OPPOSITE
direction ("up & out" ="opp." to "down & out")
to S.Part and trapped between it and the side
of this "loop" that the S.Part will bear into
--which it does adequately to nip this so
minimally reeved Tail !

Funny how these things can happen; and somewhat
challenging to a preference to making a
thorough,rigorous search through knot forms --which can seem
tedious, at least to me <sigh>.
There are many variations on the base idea.
Yes, and they can keep coming (even by inspiration w/o
the rigorous search)!
What stands out for me is that one can reeve the
RELeg U-fold through the nipping loop from either
"front" (like BWL #1010) or "back" (like "Bollard loop") side
--nicey accommodating of this variation!
Also it has a potentially interesting property when tied in ropes with low friction:
If the nub is held accordingly the nipping loop can slide remarkably freely up and down the standing part.
This can occur in #1010, w/o holding anything, just loading.
And it's a justification for those knots w/SPart structures
that are move involved before sending out the Outgoing
Eye Leg. (I've not seen any testing to show if such slippage
amounts to much (of distance or strength) in
dynamic loading
--i.e., which might be too sudden to get fast-enough slippage!?
So,
... whether the incoming leg forms the upper or the lower collar.
In the "upper"=>S.Part-side case there can be less
influence against the S.Part's nipping turn curvature;
in the latter case, there might be some help to grip
S.Part in the turn and resist the aforementioned slippage!?
Sooo, seeing some few (say, 4) aspects of the structure
to vary, and in combination, you get 4xNxY = LOTS of
*knots* to consider (or --<sigh>-- illustrate).
All this knowing that in SOME cases it's "6 of 1,
half-dozen of another" but in others "OHHHH,
my, THAT was a surprise (in risk) (e.g., the
potential spilling of a ring-loaded #1010 BWL!)
The idea was to find a secure knot that unties easy and in fewer moves.
I see too much implication (in knots literature) that merely
"slipping" (finishing w/Tail tuck of a U-fold) will produce an
easily untied knot :: in fact, often --e.g., in a tightly set
Constrictor knot-- the knot will be set hard/tight, and
it will take noticeable effort to pull even the Tail's
parallel leg of the slip-tuck into movement,
and THEN maybe no such luck in getting the
U-fold apex to come through --that that U-turn
will be in rope not happy to flex SO much,
and effectively work like a stopper.
So, if indeed quick-release is needed, aim to have
the Tail's slip-tuck made where compression of
parallel sides is NOT needed, and the binding
pressure is slight.
Thanks,
