Scotch Game: Lolli Variation: what should White play?

In the Scotch Game: Lolli Variation, the primary and most effective move for White is O-O-O. Castling queenside immediately activates the d1 along the central file, safeguards the king, and prepares an aggressive pawn storm on the kingside against Black's castled position. Modern evaluation rates O-O-O at +1.23, making it the clear theoretical standard.
