King's Gambit Accepted: Cunningham Defense

Before the first move

The King's Gambit is a romantic era opening where White sacrifices a pawn on move two to dominate the center. In the Cunningham Defense, Black prepares a cheeky bishop check on h4 to disrupt White's coordination and king safety, rather than just clinging to the extra pawn with g5.

1. e4White

White starts with e4, the most popular move in chess. By occupying the center, White prepares for rapid development. You have many ways to respond, but the most direct challenge is to mirror this move with e5.

1... e5Black · your move

Move your pawn to e5. By meeting White in the center, you prevent White from easily pushing d4 and establish your own foothold. This leads to open games where piece activity is paramount.

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

2. f4White

White plays f4, the aggressive King's Gambit. White ignores immediate safety to gain central control. You can decline the challenge with Bc5 or the Falkbeer Countergambit, but accepting the pawn is the most principled test.

Other paths here: Ke2 (Bongcloud Attack) · d4 (Center Game) · c4 (English Opening: The Whale) · Ne2 (King's Pawn Game: Alapin Opening)

2... exf4Black · your move

Capture the pawn on f4. By accepting the gambit, you challenge White to prove they have enough compensation for the material. You now have an extra pawn, though White will try to use the open lines to attack.

Other paths here: Bc5 (King's Gambit Declined: Classical Variation) · Qh4+ (King's Gambit Declined: Keene's Defense) · Qf6 (King's Gambit Declined: Norwalde Variation) · f5 (King's Gambit Declined: Panteldakis Countergambit)

3. Nf3White

White plays Nf3, the King's Knight Gambit. This move stops the immediate threat of Qh4+. White could have also tried the Bishop's Gambit or even the Breyer Gambit, but this knight move is the most solid foundational choice.

Other paths here: Qe2 (King's Gambit Accepted: Basman Gambit) · Bc4 (King's Gambit Accepted: Bishop's Gambit) · Qf3 (King's Gambit Accepted: Breyer Gambit) · Qh5 (King's Gambit Accepted: Carrera Gambit)

3... Be7Black · your move

Slide your bishop to e7 to initiate the Cunningham Defense. You are preparing to check the king from h4 anyway, forcing White to either move their king or weaken their kingside pawns to block.

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)

Where you stand

The position is sharp and tactical. Black intends to play Bh4+, forcing White to either play g3 or move the king to e2. White will likely continue with Bc4 and d4, aiming to create a powerful center and utilize the open f-file. Both players must prioritize king safety while navigating the immediate threats in this highly volatile line.

• e7-h4 Deliver a check to disrupt White's king
• f1-c4 Develop the bishop to pressure f7
• d2-d4 Occupy the center and open the dark bishop
• g8-f6 Develop the knight and prepare to castle
