#1: Wombat (wombatilim) on Apr 20, 2024 [HINT]

Initial line & color logic solves 89% with only black remaining.

R11: EL marks C3 and C11 white. LL.

C3: If R10 is black, R10C4 is also black, and R8 is invalid. The same logic can be repeated in C11.

Smile logic to finish.

Found to be solvable with moderate lookahead by wombatilim.
