I almost thought this would be LL/CL only, but right near the end the slight lack of symmetry betrayed that.

After there are only two sections with unknowns (each with a + and - in it):

If the left 2 in r27 were in c14-15 then there would be no room for the 1 in r25. Therefore r27c15 must be white.
LL finishes the left section

Then the same, mirrored:
if the remaining 2 in r27 were in c19-20 then there would be no room for the 1 in r25. Therefore r27c19 must be white
LL to finish.

Found to have a unique solution by infrapinklizzard.

Found to be solvable with moderate lookahead by infrapinklizzard.

Tricky, cool, nicely off-symmetry.
