EL 6 c17 = r7, r15-20 white
LL
Internal EL 3 r3: if it were in c11-13, it would cause a conflict in r1, so it must be in the range [c9-12] and thus c10 must be black
LL
If the 2 in r15 were in c5-6, it would force both the 3 in r15 and the 5 in r16 left into c1, creating a conflict. Therefore r15c5-6 must be white.
LL
EL 6 r18 = c15 w
LL
EL left 2 in r14: It cannot be in r14c11-12 without causing a conflict, so it must have the pixel at r14c16 as part of it. That forces the right 2 into c19-20.
LL
Look at r14c14-15. They cannot both be black. Therefore at least one must reach down into r16. No matter which goes down, r16c14 must be black.
LL to finish
Found to be solvable with deep lookahead by infrapinklizzard.#3: Joe (infrapinklizzard) on Jan 11, 2021
This is on the edge between moderate and deep lookahead, but I think it edges into the deep.
