Tough to get all singles in one step today, but plenty of one-steppers leaving lclste.

Kraken Row (6)r5

(6)r5c2 - r12c2 = r1c1 - (6=78)r13c6 - (8=362)r9c6,r8c45

(6)r5c4 - (6=2)r8c4
||
(6-4)r5c8 = (41-5)r4c73 = r4c1 - (5=78)r3c16 - (8=362)r9c6,r8c45

=> -2 r8c2, r9c45; stte

Edit. The same eliminations with an AIC:

(2=368)r8c45,r9c6 - (8=75)r3c61 - (5)r4c1 = (51-4)r4c37 = r5c8 - (4=86)r5c32 - (6)r12c2 = r1c1 - (6=78)r13c6 - (863=2)r9c6,r8c45 => -2 r2c2, r9c45; stte

...though I'd prefer this shortened non-stte (a single hp/nt required):

(8=75)r3c61 - (5)r4c1 = (51-4)r4c37 = r5c8 - (4=86)r5c32 - (6)r12c2 = r1c1 - (67=8)r13c6 => -8 r9c6, b2p2458; lste

Yarg!! Exactly the same as SCLT.

Nice! I've been thinking, should we have some kind of a standard notation and/or name for these multi-headed AICs (which I like to call Hydras)? They rarely come up, but when they do, it would be nice to be able to write and recognize them even without elaborate colors (though they're cool!).
