No guessing required but I am not sure what it means

edge logic on the 7 clue in c20 to get reds in r10-12
line logic
edge logic on the 6 in r2 to dot c2-4,19
edge logic on the 4 clue in c2 to dot r3-4
edge logic on the 2 clue in r3 to dot c3
internal edge logic on the 8 clue in r18: if it goes to the right as far as possible (c10-17) then the 6 in r18 cant be placed so you can "dot" c17r18 briefly, allowing a red to be placed in c9r18 (then undot c17r18 because the 1 clue in that row could go there)
then do the same thing again with that 8 clue, placing it in c9-16 but again the 6 clue below it cant be placed so "dot" c16r18 and make c8r18 red
again basically the same thing to make c7r18 red
line logic
edge logic the 8 clue in r18 to dot r18c2-3
line logic
edge logic the 4 clue in c2 (at the bottom) to dot c2r15-16
a questionable 2 move look-ahead edge logic on the same 4 clue in c2 (at th top) to dot c2r5 and then regular edge logic on that 4 clue to dot c2r6-10 and line logic solves it out

great solve
no guessing

of course there is probably an easier way to solve this

Excellent solve! Probably not intended but well received! Thanks Iklo.

Found to be solvable with moderate lookahead by blurglecruncheon.
