The only time I would use a 3-gun setup would be against a very high-armor enemy (i.e. more than 180 armor) with a high-luck battleship like Haruna or Iowa. If this is in a combined fleet, then this would only be used for the fast battleship in the escort fleet, since the main fleet battleships would not participate in night battle.
