After you run out of line logic, that 10 on the bottom row is solvable by some form of edge logic, then line logic to the finish line.#3: BlackCat (BlackCat) on Jul 5, 2020

C39: EL marks R1-2, R32-33, R35-38, and R41-50 white. LL.
R50: The blacks in C10-11 are part of the first 6. If it reaches as far as C7, it causes a contradiction in R49. Therefore, R50 C12-13 are black.
LL solves the rest.
Found to be solvable with moderate lookahead by wombatilim.
