Italian Game: Two Knights Open
Italian Game – Two Knights Defense, Open Variation
Definition
The Italian Game – Two Knights Defense, Open Variation is a sharp branch of the Open Games that arises after the moves 1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nxd5. It is called “Italian” because it grows out of the centuries-old Italian Game (3. Bc4), “Two Knights” because each side has developed one knight to c6/f6, and “Open” because Black recaptures on d5 with the knight, opening lines and inviting immediate tactical skirmishes.
Typical Move Order & Key Branches
- 6. d4 … exd4 7. O-O is the modern main line, leading to violent play around f7 and f2.
- 6. Nxf7!? (the Fried Liver Attack) sacrifices a knight on f7; if Black replies inaccurately, White can win swiftly, but correct defense (e.g. 6…Kxf7 7. Qf3+) yields dynamic equality.
- After 5…Na5 instead of 5…Nxd5, the game enters the Morphy Variation, technically outside the Open line.
Strategic Themes
- Race for Development: Both kings remain in the centre for several moves, so rapid mobilisation is critical.
- f7 & f2 Hot-spots: The early knight on g5 eyes f7, while Black’s pieces often counter-attack f2.
- Central Tension: The pawn structure (isolated d-pawns, semi-open e-files) gives each side chances to seize the initiative with timely pawn breaks (…c6, …e4 or d4-d5).
- King Safety vs Activity: White sometimes castles long; Black may leave the king in the centre or castle queenside, creating opposite-side attacks.
Historical Background
The line was already known in the 19th century to Italian masters Greco and Polerio, but it exploded in popularity after Paul Morphy (pre-Civil War America) and Wilhelm Steinitz (late 1800s) analysed its labyrinthine tactics. 20th-century theoreticians, notably Euwe, Boleslavsky and Geller, refined defensive resources for Black, proving that the once-feared Fried Liver is sound for the second player with best play. In contemporary praxis the variation remains a favourite surprise weapon, especially in rapid and blitz.
Illustrative Mini-Game

White’s queen and rook cooperate to deliver mate after a cascade of checks — a textbook example of what both sides must watch for in the Open Variation.
Famous Encounters
- Marshall – Burn, Ostend 1905 – A pioneering battle in which Frank Marshall unleashed novelties involving …Nd4 and …b5 ideas.
- Anand – Karpov, Wijk aan Zee 1996 – Anand deployed the Fried Liver; Karpov’s precise defense highlighted modern antidotes.
- Kasparov – Short, Tilburg 1991 – Kasparov steered into the Open line, sacrificed material, and out-prepared Short in a bristling tactical slug-fest.
Typical Tactical Motifs
- Forks on c7 & e6: The knight on d5 (or f4) can fork king & rook.
- Queen Sacrifice on e6: Common in lines where the Black king sticks to e8 after …Nxd5.
- Rook Lift R–e1–e4–h4: White swings the rook across to launch a king-side assault.
Interesting Facts & Anecdotes
- Because of the early outpost on g5, computers once evaluated the position +2 for White; deep engines now swing back to ≈0.00, showing how concrete calculation trumps static heuristics.
- In scholastic chess the Fried Liver Attack (6.Nxf7) is notorious; countless juniors have scored “smothered” checkmates thanks to Black’s misplaced king on f7.
- Mikhail Tal, famous for sacrifices, confessed that he disliked facing the Open Variation as Black, preferring 5…Na5 because “everything is hanging at once and even a magician may blunder.”
Practical Tips
- If you play White, learn the forcing lines 6.d4 exd4 7.O-O and the critical Bishop retreat ideas (8.Re1, 9.Qh5+).
- As Black, memorise the antidote to 6.Nxf7 — 6…Kxf7 7.Qf3+ Ke6 8.Nc3 Nb4! — and decide early whether you prefer the counter-punching 5…Nxd5 or the calmer 5…Na5.
- In rapid games, tempo often outweighs material. Do not cling to the extra pawn on d5 if your king lags in development.
