This opening is all about a central break and rapid development. After 3.f4, you challenged Black's e5 pawn, and they responded not by defending it but by pinning your knight with Bb4. Your recapture 4.fxe5 opens lines — Black's knight is under attack from the pawn, and their bishop on b4 is aiming at your knight but not yet threatening anything decisive. Black's biggest problem is that their king is still in the centre, and they are already behind in development. Your plan is simple: keep the initiative, open the game, and punish any slow move. The engine says +2.50 which means you have a near-winning advantage — the position is close to decided if you play accurately.
The Move Black Must Play (and How You Punish It)
Black's best move is Bxc3, capturing your knight. This has been played in 115,197 games — the overwhelming majority of responses. After Bxc3, you recapture with dxc3. Then Black's best continuation is Ng8, retreating the knight all the way back — a sign of how uncomfortable their position already is. From there you continue with Qh5, building a powerful attack. Even in this 'best' line, White scores 52.1% — a solid plus. Black's other options are far worse for them, so when you see Bxc3, understand that you have already achieved a wonderful position from the opening.
The Mistakes You Need to Recognise and Punish

White wins 79.3% of these games. - Qe7 (298 games): Loses about 2.5 pawns — a serious mistake. White's score jumps to 77.2%. If your opponent plays any of these, trust your advantage and keep developing with tempo.
