One chess opening that can yield exciting games out of the King’s Gambit is the “Cunningham Defense” (3.Nf3 Be7).
In this article, we look at this opening and the potential it offers.
Cunningham Defense: A Brief Overview
The Cunningham Defense in chess is initiated with the moves 3.Nf3 Be7
It essentially threatens a check on h4 that can permanently prevent White from castling.
If White does not immediately develop the king’s bishop, Ke2 would be forced, which hems the bishop in.
Thus, the Cunningham Defense sets a sort of tactical snare right at the beginning of the game.
Potential Line of Play in the Cunningham Defense
A sample line that exemplifies the potential of the Cunningham Defense is 4.Nc3 Bh4+ 5.Ke2 d5 6.Nxd5 Nf6 7.Nxf6+ Qxf6 8.d4 Bg4 9.Qd2.
This line highlights how the Cunningham Defense can lead to complex positions that require careful navigation.
In this situation, White has strong central control with pawns on d4 and e4, while Black relies on the discomfort of the white king as compensation.
White’s Response to the Cunningham Defense
To avoid the potential pitfalls posed by the Cunningham Defense, the most popular response for White is 4.Bc4.
However, Black can still play 4…Bh4+, forcing 5.Kf1.
Here, the game could devolve into the wild Bertin Gambit or Three Pawns’ Gambit (5.g3 fxg3 6.0-0 gxh2+ 7.Kh1), which was commonly played in the nineteenth century.
In modern practice, it is more common for Black to develop with 4…Nf6 5.e5 Ng4.
This line is known as the “Modern Cunningham.”
It creates a different kind of game, where Black takes a more aggressive stance early on, attempting to seize control of the board.
The Euwe Variation of the Cunningham Defense
Another interesting line to explore is the Euwe Variation (5…Ne4!?).
Although this line has not been thoroughly explored, it seems playable and presents a number of “trappy” ideas that can catch an unprepared opponent off guard.
It serves as yet another example of the flexibility and richness of the Cunningham Defense.
Evaluation of the Cunningham Defense
The Cunningham Defense is generally evaluated at around +0.00 to -0.35 for white.
