Hungarian Opening starts with 1.g3. It is not really an opening because the idea of the first move is generally to transpose into a well-known opening. White starts with 1.g3, keeping the options open to transpose into various openings.
The drawback of move 1.g3 is that it allows black to occupy the center first. Black has various moves like c5, d5, e5 or Nf6. White will choose his opening depending upon black’s reply.
We will look at various set-ups that can happen after 1.g3.
King’s Indian set-up
After 1.g3 d5, white can play the king’s Indian attack set-up. For example 2.Bg2 e5 3.d3 Nf6 4.Nd2 Bd6 5.e4 c6 6.Nf3 0-0 7.0-0
