About the Vienna Game
After 1.e4 e5, White plays 2.Nc3 instead of Nf3. It keeps the f-pawn free, so White can later play f4 like a King's Gambit.
The Vienna Gambit f4 aims to open the f-file for an attack.
Bc4 with Qh5 or Qf3 tricks targets f7; beginners must watch out.
Black's best answers are ...Nf6 with ...d5, hitting the centre fast.
