Vienna Game Players
For all players with 2.Nc3 in their repertoire against 1...e5.
It's common knowledge that 1...e5 players are often well-prepared to equalize against the many overused gambit lines White has in store with openings such as the Italian and the Scotch game—try to throw them off-guard with the less common 2.Nc3! This opening is versatile as it can accommodate both aggressive players with the Vienna Gambit, as well as the more positional, strategical players with a slow Italian or KIA-esque setup.
If you practice all three of them, you could become a master of the Vienna Game!
