Sicilian Defense: Accelerated Dragon - Modern Bc4 Variation (7.Bc4, after 5.Nc3 5...Bg7 6.Be3 6...Nf6)
White develops with 7.Bc4, then retreats to 8.Bb3 after your castling. Meet it with ...Re8, then after 9.f3 d5 10.exd5 Nb4 11.Nde2, play ...e6, lining your rook up behind that pawn against White's bishop on e3. Watch the 10.f4 trap, where ...Ng4 and ...Qb6+ win material. You aim for a sound center against White's queenside majority.
Let's learn the Modern Bc4 Variation! White brings the bishop to c4, eyeing f7 and d5, then retreats it to b3. We castle for safety and push ...d5 to challenge White's center. Let's begin with 1.e4.

Exchange Variation (5.Nxc6)
White grabs your knight with 5.Nxc6, then jumps the queen to d4 and later pushes e5-e6 to chase your pieces. Recapture bxc6, meet 7.e5 with Nd5, and answer 8.e6 with Nf6, letting White overextend. If White grabs your pawn with 12.Qxe5, hit back with Bb4+ and win material. Aim for an endgame where your active pieces and extra material are winning.
