The Three Knights Game arises after 1.e4 e5 2.Nf3 Nc6 3.Nc3 and falls under ECO code C46. White follows the classic principle of developing knights before bishops, reasoning that both knights belong on f3 and c3 regardless of what follows. Although 3. Nc3 does not create any direct threats, it is surprisingly difficult for Black to deviate from symmetry, as there are no attractive ways to break the pattern. The natural and overwhelmingly popular reply is 3...Nf6, which transitions into the quiet but solid Four Knights Game. Bishop development is less appealing for Black at this point since no ideal square presents itself. One ambitious alternative is 3...f5?, the Winawer Defence, where Black gambits a pawn. The main response is 4. d4, though even the simple 4. exf5 should favor White objectively, despite Black retaining some practical chances at the amateur level. With 70.6 million Lichess games across all rating levels, it is a well-established opening choice.
