About the Van Geet Opening
White starts with 1.Nc3, an offbeat but sound move. It develops a knight and can later turn into a Vienna, a Pirc-like or a d4 game.
The knight controls e4 and d5; White often follows with e4.
It blocks the c-pawn, so plans with c4 are harder.
Black can take the centre with ...d5 and ...e5; White plays for surprise.
