Défense des deux cavaliers - Lignes 4.O-O
White castles early with 4.O-O, skipping c3, so grab the e4 pawn with ...Nxe4. After 5.Re1 d5 6.Bb5 Bc5, meet 7.d4 with ...exd4, and if 8.Nxd4 castle with O-O. Watch for 5.Re1, a common mistake you punish. You land up a pawn with a strong attack, sometimes even winning material outright.
Apprenons les lignes 4.O-O ! Les Blancs font le petit roque, puis clouent notre cavalier avec 6.Bb5. Nous ripostons avec ...Bc5, qui menace une fourchette, et nous gagnons un pion avec une forte attaque. Commençons par 1.e4.

Partie du fou moderne (4.d3)
White enters the Italian with Bc4 and settles for the quiet 4.d3. Meet it with ...Be7, castle, and after 6.c3 d5 7.exd5 Nxd5, giving your bishop on e7 more room. Aim for an active, comfortable setup where your pieces develop freely and your d5 knight eyes the center.

Ligne de l'échec du fou (6.Bb5+)
White checks with 6.Bb5+, so block with ...c6 and recapture ...bxc6, then meet 8.Bd3 with ...Nd5 and ...Nf4 to grab the bishop. Castle, let White take on e5, and push ...c5, even though it lands isolated. Watch for the 8.Ba4 trap where ...Qd4 nets you a piece. You reach the bishop pair against White's isolated and doubled d-pawns.

Variante italienne (4.Nc3)
After 4.Nc3, take the pawn with Nxe4 and meet Nxe4 with d5, hitting bishop and knight at once. Follow up Qxd5, Qd6, Bg4 pinning the knight, and Bh5 to keep it pinned. Castle queenside, then push f5 and f4 with the bishop pair.

Variante ouverte (4.d4)
White opens the center with 4.d4, steering you into the Scotch Gambit. Meet it with 4...exd4, 5...d5, 6...Ne4 and 7...Bc5, then castle with 8...O-O and defend your knight with 12...Qe7. You land in a position with an isolated c7 pawn against White's queenside majority.
