About the Hungarian Opening
White starts with 1.g3 to fianchetto the bishop at once. It is flexible and can transpose to the English, Réti or King's Indian Attack.
Bg2 controls the long diagonal and the centre from afar.
White chooses c4, d4 or e4 later, depending on Black's setup.
Black can grab the centre with ...d5 and ...e5; White then hits it.
