About the Main Line

The Main Line meets the bishop check with 6. Bd2, which blocks and attacks the b4-bishop but abandons the d4-pawn. Black nearly always accepts with 6...Qxd4, hitting the e4-knight. After 7. Bxb4 Qxe4+, White interposes on e2 and relies on the bishop pair, the dark squares and a lead in development. The less common 6...Bxd2+ exchanges bishops instead of taking material. The engine rates the position as roughly balanced, and Lichess results are close to even.
