Move by move

1. 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.
2. 1...e5 – You respond symmetrically with 1...e5: staking your claim in the center, preventing d4, and opening paths for your own pieces.
3. 2.Nf3 – White develops the king's knight toward the center, attacking your e5 pawn and preparing rapid kingside castling in two moves.
4. 2...Nf6 – The Petrov Defense! With 2...Nf6 you disregard White's attack on e5 and launch a symmetrical counterstrike against their e4 pawn.
5. 3.Nxe5 – White captures your central e5 pawn with the knight, hoping for an immediate advantage or tempting you into a tactical blunder.
6. 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.
7. 4.Nxf7 – The dreaded Cochrane Gambit! White sacrifices a full knight on f7 to dismantle your castling shelter and launch a wild onslaught.
8. 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.
9. 5.d4 – White advances d4 to seize the center with pawns and open lines for both bishops, hoping for a devastating, swift assault.
10. 5...c5 – Immediate counterattack in the center with 5...c5! You blast White's Cochrane plan by targeting d4 before White can target you.
11. 6.d5 – White is forced to push d5 to avoid collapsing in the center, but closes attacking lines and makes your king completely safe.
12. 6...g6 – You set up the fianchetto with 6...g6: preparing the g7 shelter for your king and liberating the long diagonal for your bishop.
13. 7.Nc3 – White develops the knight to c3 attempting to regroup their forces, but finds themselves a full piece down with no compensation.
14. 7...Bg7 – You place the bishop on the long diagonal on g7: commanding the board and setting the stage for an effortless conversion of material.
