  1. Before the first move

    The Portsmouth Gambit is a sharp, provocative weapon where White sacrifices a wing pawn to deflect Black's c-pawn. By offering the b4-pawn, White aims to seize the center quickly with d4 and gain a lead in development. Black must choose between accepting the gift or maintaining a solid structure while the game heats up early.

  2. 1. e4White

    White starts with e4, the most popular move in chess, seeking to control the center and facilitate quick piece activity. While Black has many ways to respond, such as the solid e5 or the French Defense with e6, the most ambitious and fighting choice is the Sicilian Defense.

  3. 1... c5Black · your move

    Move your pawn to c5. By playing the Sicilian Defense, you immediately create an asymmetrical battle. You are challenging White's control of the d4-square and preparing to trade your wing pawn for White's central d-pawn later in the game.

    Other paths here: f6 (Barnes Defense) · g5 (Borg Defense) · h6 (Carr Defense) · f5 (Duras Gambit)

  4. 2. Nf3White

    White plays Nf3, the main line of the Sicilian. This move is vastly more common than sidelines like the Bowdler Attack with Bc4 or the Keres Variation with Ne2. It keeps White's options open while pressuring the center and preparing for the Open Sicilian.

    Other paths here: Qg4 (Sicilian Defense: Amazon Attack) · Bc4 (Sicilian Defense: Bowdler Attack) · Nh3 (Sicilian Defense: Brick Variation) · g4 (Sicilian Defense: Grob Variation)

  5. 2... Nc6Black · your move

    Bring your knight out to c6. This move develops a piece to its most natural square, adding pressure to the d4 and e5 squares. You are reinforcing your control over the center and preparing for a complex middle-game struggle.

    Other paths here: f5 (Sicilian Defense: Brussels Gambit) · h6 (Sicilian Defense: Bücker Variation) · g6 (Sicilian Defense: Hyperaccelerated Dragon) · e5 (Sicilian Defense: Jalalabad Variation)

  6. 3. b4White

    White surprises you with b4, the Portsmouth Gambit. Instead of the standard Rossolimo Attack with Bb5 or the quiet d3, White gambles a pawn for central control and initiative. You must now decide whether to capture the pawn or continue developing calmly.

    Other paths here: Bb5 (Sicilian Defense: Nyezhmetdinov-Rossolimo Attack) · b3 (Sicilian: 2...Nc6 3.b3) · Bc4 (Sicilian: 2...Nc6 3.Bc4) · d3 (Sicilian: 2...Nc6 3.d3)

  7. Where you stand

    The game has reached a critical junction where Black must decide how to handle the b4 sacrifice. If Black captures with Nxb4 or cxb4, White will use the time to establish a powerful center with c3 and d4. Both sides are looking at a tactical battle where White has the initiative, but Black has the extra material and a very resilient position.

    • c6-b4 Capture the gambit pawn with the knight
    • c2-c3 Support the center and kick the knight
    • d2-d4 Claim the center with a d4 push
    • e7-e6 Solidify the center and prepare bishop development
