Practice this lineThe idea
White develops the bishop to e3 and plans f3, Qd2, g4 and long castling, then storms the kingside with the pawns. After 6...e5, the knight retreats with 7.Nb3, keeping an eye on d4 and c5.
With the kings usually on opposite sides, the game becomes a race: White attacks on the kingside, Black on the queenside.
Plans for White
Play f3, Qd2 and O-O-O, then g4 and g5 to push away the knight on f6 and loosen Black's king. The pawn on f3 also stops ...Ng4, which would otherwise hit the bishop on e3.
Watch the d5 square: getting a knight there, or exchanging pieces so that Black can't control it, gives White a lasting edge.
Plans for Black
Black usually replies 7...Be6, controlling d5, then plays ...Be7, ...O-O and ...Nbd7. The counterattack comes with ...b5 and ...b4, kicking the knight on c3, and a rook on c8.
The ...d5 break, when it works, frees Black's position and opens lines toward White's king.
Watch out for
For both sides, speed. With opposite-side castling, a single slow move can decide the race. Count tempi before spending one on defense.
For Black, giving up control of d5. If White can play Nd5 and recapture with a pawn or piece without Black getting play, Black is left with a weak d6 pawn and no counterplay.
