Grünfeld Defense: Brinckmann Attack, Grünfeld Gambit Accepted

Before the first move

The Grünfeld Defense is a dynamic counter-attacking opening where Black allows White to build a large center only to strike back at it immediately. In this Brinckmann Attack variation, White accepts a gambit pawn on c7, leading to a sharp position where Black gains rapid development and piece activity in exchange for the material.

1. d4White

White starts with d4, the most common alternative to the King's Pawn opening. By controlling e5 and d4, White prepares a structured game. You'll need to decide how to respond: the flexible Nf6 is standard, but some players try the Englund Gambit with e5 or the solid d5.

1... Nf6Black · your move

Develop your knight to f6. This is the most flexible response to d4, preventing White from immediately playing e4 and keeping your options open for several different defensive setups. You are preparing to influence the center without committing your pawns just yet.

2. c4White

White plays c4, the signature move of the Queen's Gambit family. This increases central tension and prepares to gain more space. You can now enter the Nimzo-Indian with e6, the King's Indian with g6, or even the sharp Benko Gambit with b5 if you are feeling aggressive.

Other paths here: f4 (Canard Opening) · g4 (Indian Defense: Gibbins-Weidenhagen Gambit) · e4 (Indian Defense: Omega Gambit) · d5 (Indian Defense: Pawn Push Variation)

2... g6Black · your move

Fianchetto your kingside by playing g6. You are signaling your intent to place your bishop on g7, where it will exert long-range pressure across the board. This move is the hallmark of the King's Indian and Grünfeld defenses, favoring piece activity over a fixed pawn center.

3. Nc3White

White plays Nc3, developing a piece and strengthening the grip on d5. This is the most testing move. You must now choose between the King's Indian Defense with Bg7 or the Grünfeld Defense with d5. Other options like c5 or d6 lead to different strategic battles entirely.

3... d5Black · your move

Strike at the center with d5. This is the defining move of the Grünfeld Defense. You are challenging White's c4 pawn and creating immediate tension. If White captures, you will use your knights and bishops to attack the remaining central pawns from the flanks.

Other paths here: Bg7 (King's Indian: 3.Nc3 Bg7) · c5 (King's Indian: 3.Nc3 c5) · c6 (King's Indian: 3.Nc3 c6) · d6 (King's Indian: 3.Nc3 d6)

4. Bf4White

White plays Bf4, a solid developing move that targets d5 and c7. This avoids the main lines of the Exchange Variation. You should continue with your plan of kingside development, though some players choose to challenge the center immediately with c5 or the solid c6.

Other paths here: e3 (Gruenfeld: 4.e3) · g3 (Gruenfeld: 4.g3) · g4 (Grünfeld Defense: Gibbon Gambit) · f3 (Grünfeld Defense: Lutikov Variation)

4... Bg7Black · your move

Fianchetto your bishop to g7. This piece is the soul of your position, staring down the long h8-a1 diagonal. From here, it supports your center and prepares for a future kingside castle, while remaining ready to strike at White's queenside later in the game.

5. e3White

White plays e3, creating a solid pawn triangle in the center. This is a very reliable setup. You should now finish your kingside development by castling. Alternatively, the move c5 is a sharp way to challenge the center immediately before White can complete their development.

5... O-OBlack · your move

Castle kingside to bring your king to safety and activate your rook. In the Grünfeld, king safety is paramount because the center often opens up very quickly. You are now fully developed on the kingside and ready to start your counterplay against White's center.

Other paths here: c5 (Gruenfeld: 4.Bf4 Bg7 5.e3 c5)

6. cxd5White

White plays cxd5, initiating the central exchanges. This is a critical moment. You must recapture with the knight to maintain your central influence. If White instead played Qb3 or Rc1, the game would remain more closed and focused on slow positional pressure.

6... Nxd5Black · your move

Capture the pawn on d5 with your knight. This centralizes your piece and attacks the knight on c3 and the bishop on f4. You are inviting White to trade pieces, which will help clear the way for your heavy pieces to enter the game.

7. Nxd5White

White plays Nxd5, forcing your queen into the center. This is part of White's plan to win the c7 pawn. You must recapture with the queen to keep your presence in the middle of the board and prepare for the tactical complications that are about to follow.

7... Qxd5Black · your move

Recapture on d5 with your queen. This is a very active square for the queen, as it eyes the d4 pawn and the g2 square. Although you are about to lose the c7 pawn, your queen's centralized position provides excellent compensation and attacking chances.

8. Bxc7White

White plays Bxc7, accepting the gambit. You are now down a pawn, but your pieces are much better coordinated. You'll need to use your development advantage to create threats against White's uncastled king. The main line continues with Nc6, developing your last minor piece.

Where you stand

The position is dynamically balanced. White is up a pawn but lags in development and has not yet castled. Black's plan is to develop the remaining knight to c6 and use the active queen and g7-bishop to pressure White's center. White must prioritize kingside development and king safety to realize the extra pawn in the long run.

• b8-c6 Develop the knight to pressure d4
• g1-e2 Prepare to castle by developing the knight
• c8-g4 Pin the knight to create central pressure
• e1-g1 Bring the king to safety quickly
