King's Gambit Accepted: Hanstein Gambit

Before the first move

The King's Gambit is one of chess's most romantic and aggressive openings, where White sacrifices a pawn on move two to destroy Black's center. In the Hanstein Gambit, Black accepts the challenge and holds the extra pawn with g5, leading to a sharp tactical battle where White gains quick development in exchange for the material.

1. e4White

White opens with e4, the most common and ambitious first move. By occupying the center, White prepares to develop pieces rapidly. You must now decide how to respond; while e5 is the traditional reply, other major defenses like the Sicilian or French are also very common.

1... e5Black · your move

Push your pawn to e5. By meeting White in the center, you prevent them from grabbing more space with d4 and establish your own foothold. This leads to an open game where piece activity and tactical awareness are paramount from the very first moves.

2. f4White

White plays f4, the bold King's Gambit. White is willing to lose a pawn to gain rapid development and central control. You can decline the gambit with moves like Bc5 or the Falkbeer Countergambit, but accepting it is the most testing way to play for a win.

2... exf4Black · your move

Capture the pawn on f4. By accepting the gambit, you take the material lead and challenge White to prove they have enough compensation for the pawn. You will now have to defend your extra pawn while White tries to overwhelm you with faster development.

3. Nf3White

White plays Nf3, the King's Knight Gambit. This move stops the annoying Qh4+ check and prepares to develop the kingside. White could have tried the Bishop's Gambit with Bc4 or the Basman Gambit with Qe2, but Nf3 is the most solid and common choice.

3... g5Black · your move

Push your pawn to g5. This is the most ambitious way to defend your extra f4-pawn. By anchoring the pawn, you make it very difficult for White to win the material back, though you are slightly weakening your kingside in the process.

Other paths here: h6 (King's Gambit Accepted: Becker Defense) · Ne7 (King's Gambit Accepted: Bonsch-Osmolovsky Variation) · d6 (King's Gambit Accepted: Fischer Defense) · f5 (King's Gambit Accepted: Gianutio Countergambit)

4. Bc4White

White plays Bc4, aiming directly at your f7-pawn. This is a very aggressive setup. White could also choose the Quaade Gambit with Nc3 or the Rosentreter Gambit with d4, but this bishop placement is the most traditional way to pressure your position.

Other paths here: Nc3 (King's Gambit Accepted: Quaade Gambit) · d4 (King's Gambit Accepted: Rosentreter Gambit) · h4 (King's Gambit Accepted: King's Knight's Gambit)

4... Bg7Black · your move

Fianchetto your bishop to g7. This move reinforces your g5-pawn and prepares to put pressure on the long diagonal. It also clears the way for you to castle kingside, providing a safe home for your king behind a wall of pawns.

Other paths here: g4 (KGA: 3.Nf3 g5 4.Bc4 g4) · Nc6 (KGA: Blachly Gambit) · d6 (King's Gambit Accepted: King's Knight's Gambit)

5. O-OWhite

White castles, completing the Hanstein Gambit setup. White is now fully developed and ready to strike at your center. They could have played d4 first, but castling ensures the king is safe before the real tactical fireworks begin on the f-file.

Other paths here: d4 (KGA: Hanstein Gambit) · h4 (King's Gambit Accepted: Philidor Gambit)

Where you stand

The position is highly unbalanced. White has a lead in development and a safe king, while Black is a pawn up with a solid kingside structure. White will look to break the center with d4 and g3, while Black should focus on developing the queenside and challenging White's central control with d6 and Nc6.

• d2-d4 Occupy the center and open lines
• d7-d6 Solidify the center and free the bishop
• b8-c6 Develop the knight to pressure d4
• g2-g3 Challange the f4 pawn to open the f-file
