Move by move

1.e4 – White opens with the classical 1.e4, controlling d5 and f5 and freeing diagonals for both the f1 bishop and the queen to begin an open game.
1...e5 – You respond symmetrically with 1...e5: staking your claim in the center, preventing d4, and opening paths for your own pieces.
2.Nf3 – White develops the king's knight toward the center, attacking your e5 pawn and preparing rapid kingside castling in two moves.
2...Nf6 – The Petrov Defense! With 2...Nf6 you disregard White's attack on e5 and launch a symmetrical counterstrike against their e4 pawn.
3.Nxe5 – White captures your central e5 pawn with the knight, hoping for an immediate advantage or tempting you into a tactical blunder.
3...d6 – The essential golden move! With 3...d6 you kick White's knight first, ensuring you can recapture on e4 in complete safety next turn.
4.Nxf7 – The dreaded Cochrane Gambit! White sacrifices a full knight on f7 to dismantle your castling shelter and launch a wild onslaught.
4...Kxf7 – You capture the knight with your king on f7: accepting the challenge with cool nerves and holding an extra piece to your name.
5.d4 – White advances d4 to seize the center with pawns and open lines for both bishops, hoping for a devastating, swift assault.
5...g6 – Masterly defensive move with 5...g6: preparing an artificial shelter for your king on g7 and an active fianchetto with Bg7.
6.Nc3 – White develops the knight to c3 to support the center and prepare castling, trying to pile pressure against your king position.
6...Kg7 – The king finds a safe, impenetrable sanctuary on g7! The danger has passed and your full extra piece decides the game easily.
7.Bc4 – White's bishop steps out to c4 aiming down your king's diagonal, in a desperate bid to manufacture tangible threats on the flank.
7...c6 – You shore up the defense precisely with 7...c6: barring White's pieces from b5 and d5 and preparing to smoothly convert your material.
