Subgoal: Minimize the odds of an opponent’s bingo

Resolution: While you have a slight lead, there is much to fear in this puzzle, as your opponent often has a bingo. You must block opponent bingos while scoring enough points to outscore them in the endgame.

While it seems like column 14 is the biggest threat, the bottom right corner is actually more threatening, as any bingo that plays in column 14 also plays row 15. The bingo line that you actually need to block is the A in row 13, as this allows your opponent to play UNmARRED or gURNARDS with racks that otherwise have no playable bingos. Thus, the best play is any good scoring play that blocks these alleys, such as JEU m11 (20).
