Chess Opening Theory/1. Nc3/1...Nf6

van Geet opening A00 van Geet opening 1...Nf6 A flexible continuation where Black passes the decision on making a pawn move in the centre back to White. There is little independent character and the game usually transposes shortly to another opening. Whether 2. e4 or 2. d4, Black can move order into a classical French defence (2...e6, then either 3. d4 d5 or 3. e4 d5, respectively) or the Pirc (2...d6 3. d4 or 3. e4). Otherwise, 2. e4 and Black's transpositional options include the Vienna game, 2...e5; and an Alekhine defence, 2...d5. 2. d4 may lead to a Chigorin closed game. 2. g4? is called the Tübingen gambit with a similar character to the Bronstein aka the Gibbins-Weidenhagen gambit, 1. d4 Nf3 2. g4, to which this may transpose. After 2...Nxg4 3. e4 discovers an attack on the knight. Theory table 0 Vienna game 2. e4 e5 3. f4 d5 Pirc defence 2. e4 d6 3. d4 Nbd7 four knights game 2. Nf3 Nf6 3. e4 e5 Tübingen gambit 3. g4?
