Van Geet Opening Middlegame (1.Nc3 / 1.Nc3 e5 / 1.Nc3 d5 2.f4 d4 3.Ne4 e5) Chess Puzzles

The van geet opening middlegame begins with 1.Nc3, the defining move of the Van Geet or Dunst Opening, before White commits a central pawn. Because 1.Nc3 leaves both d- and e-pawns flexible, Black’s reply—such as ...d5, ...e5, ...Nf6, or ...c5—largely determines the resulting middlegame. This is an obscure, transpositional topic rather than one universally documented variation with a fixed move order.
