Berlin Defense (2...Nf6)
1.e4 e5 2.Bc4 2...Nf6 3.d3

Modern main line. After 3.d3 Nc6 4.Nf3, we reach an Italian-style game but sidestep Petrov Defense (since Black has committed to ...Nc6, not ...Nxe4).
2.Ac4 en lugar de 2.Cf3: evita la Petrov y mantiene la flexibilidad hacia la Italiana o la Vienesa.
1.e4 e5 2.Bc4

La Apertura del Alfil (1.e4 e5 2.Ac4) apunta a f7 desde el segundo lance sin comprometer el caballo de rey. A menudo transpone a la Italiana (si 2...Cf6 3.Cf3 Cc6) o a la Vienesa (si 2...Cf6 3.Cc3). Ventaja principal: evita la Defensa Petrov (que requiere 2.Cf3 Cf6). Jugada al más alto nivel por Anand y Nakamura en blitz. Carga teórica baja, ideal para jugadores que quieren la simplicidad de la Italiana sin el riesgo de la Petrov.

1.e4 e5 2.Bc4 2...Nf6 3.d3

Modern main line. After 3.d3 Nc6 4.Nf3, we reach an Italian-style game but sidestep Petrov Defense (since Black has committed to ...Nc6, not ...Nxe4).
1.e4 e5 2.Bc4 2...Nf6 3.Nf3 Nxe4 4.Nc3

A sharp line where White sacrifices the e4 pawn for development. Black must play precisely to hold the position.
1.e4 e5 2.Bc4 2...Bc5 3.c3

Black mirrors White's bishop development. After 3.c3 Nf6 4.d4, we transpose to the Italian Game Giuoco Piano.
Play the Bishop's Opening to learn the ideas before the Italian Game, fewer tactical pitfalls than the Fried Liver/Two Knights lines.
Use 2.Bc4 3.d3 specifically to avoid Petrov Defense players. Study the transition to Vienna Game (with Nc3) and Italian Game (with Nf3).
Add the Boden-Kieseritzky Gambit for sharp play. As an anti-Petrov weapon at higher levels, 2.Bc4 remains completely valid.
Yes, particularly as an anti-Petrov weapon. Kaufman's system (2.Bc4 3.d3) has been used at the top level including by Carlsen in blitz games. Less theory than the Italian Game.
The Bishop's Opening plays 2.Bc4 before 2.Nf3. This avoids the Petrov Defense (2...Nf6) entirely and can transpose to the Vienna (with Nc3) or Italian (with Nf3). Move-order flexibility.
2...Nf6 (Berlin Defense) is most principled. It challenges e4 and prepares ...Nxe4 tactics. 2...Bc5 develops symmetrically and often transposes to Italian Game lines after 3.Nf3.
After 2...Nf6 3.Nc3 Nxe4, White plays 4.Qh5, hitting the e4-knight and threatening Qxf7#. Black's correct reply is 4...Nd6, the wild but fully sound Frankenstein-Dracula Variation: the knight defends f7 and hits the c4-bishop, and Black holds with ...Nc6 and a queenside pawn storm. It is a sharp fight, not a refutation. (The separate Boden-Kieseritzky Gambit arises after 3.Nf3 Nxe4 4.Nc3, where White sacrifices the pawn for development.)
Excellent, simple plans, natural development, and it teaches the importance of attacking f7 from move 2. A great stepping stone to the Italian Game or Vienna Game.
La apertura clásica 1.e4 e5 2.Cf3 Cc6 3.Ac4: principios sólidos, tácticas ricas.
Una apertura subestimada, cortante al nivel de club: desarrollo clásico con planes de ataque agresivos.
La defensa a 1.e4 e5 más sólida: simétrica, equilibrada y difícil de batir.
