uneasy truce JC, 'w/o UR' confused since no UR SIS used in my path for site puzzle Sep 20; all the same,
'c8=8 => contradiction' isn't by any stretch a step in a path.

Y-10 unsolved - a path a..z:

1. SIS: (57)ac6=WW(31)a6*,d4/(1)g46 - (3)f6=f7-(357=4)ab7b8-a5=(24')c45 # -5c5
[(24')c45==(57)ac6-(7)h6=*h8-(7=64)ci9-(64')c89=(24')c45]
||
(7-2)h4=c4 # +(24)c4
// SS(3)cd9.db4; -3b7
// YW(15.7)a53,c6; -7a6
// xy: (6=9)h1-e1=(9-1)e8=(1-6)e5=f6 # -6h6.f1

Y-11: Symmetry=None, Start=25, SSTS=28, SG=11.25, SE=8.6

SG did this with 10 AIC, too long (2 chaining steps, 0 patterns).

Are these blue swimmers a type of crab? Sorry Kate, but I haven't seen this type before.

They are a crab jacalmi. I once saw whole lot of them walking on the sand. It was quite a sight as the blue was so prominent.

Kobold,

1. You missed to mention one last step in your solution for site puzzle Sep 20 :

Either UR(27)ei13=3i1, or [(9=2)a2-(2=4)c1-4c3=4h3-(4=9)h7]-(9=2)a7

2. I note that you don't see the relations between our 2 solutions for that puzzle.

A word to the wise is enough!

JC

JC - a rebut:
------------------------------------
i) c8=8 depth 27 net => contradiction (in other words blatant trial and error, not a chain)

ii) you are right that the path is incomplete, (cut & paste error)

iii) you didn't post a solution - to what do I relate ?

'Le bon Dieu est dans le détail'

Cheers

Like Bud's:
1. Note e2f3=24,ghi7=247.Unique possibilities to 36.
2. Whether a8=5;OR b8=5,b56=24;a23=24.UP81.

Blue crabs are local around here, too. The blue turns red when cooked.

Maryland is for Crabs is the state slogan. See Kathy from Maryland's page for an invitation to eat her local delicacy.

Y-11 : 'Le bon Dieu est dans le détail' :

h4=9 -> e4=3, h6=5, ef6=14, gi6=68, i45=14, i2=7=e1; e5=5, d78=1; [(82=9)ie9-9d7=(9-8)g7=8a7]-(8=5)b9; a4=5 :=> a4=59; UP81

My go at Y-11, making use of two Unresolvable Rectangles (URs).
1. Unique possibilities to 28.
2. Whether h4=9;OR a4=9,a2=2=i9,h1=7=i8,g8=6;h8=3.UP31.
3. If h4=9=g9,h6=5,ef6=14=i45,c5=8(to avoid 14UR@ci45),a3=8=b9,i2=7=c3,g7=8(to avoid 68UR@gi68),cg8=14;column d is devoid of 1.So a4=9.UP81.

Forgot also d7=9 after h4=9 in step 3.

so many different paths for Y-11, this is the two step path I found;
I wouldn't expect net solvers like JC and Alfred to find loops, but step 1 below simplifies the problem.

1. { (1468=7)i2456-h1=(7-2)e1=b1-a2=(2-9)a4=(9-68'')ai6=(68)g6 }
-1i89, -4i8, +(27)e1, -7a2, -2b2, +(29)a4, More...
