Chess has a huge number of openings, defenses, variations, and attacking systems. Some are played regularly at the highest level, while others are less common but can give players a chance to reach unfamiliar positions.
Learning an opening does not simply mean memorizing a long list of moves. It is more useful to understand why the moves are played, where the pieces belong, and what each side is trying to achieve. The openings below cover several different styles, from direct counterattacks to flexible defensive systems.
Scandinavian Defense
The Scandinavian Defense is one of the most direct responses to White’s first move, 1.e4. Instead of allowing White to build a pawn center, Black immediately challenges the pawn on e4.
The opening begins with the moves:
1. e4 d5
White can capture the pawn with 2. exd5, after which Black normally recaptures it. One of the most familiar ways is 2…Qxd5, bringing the queen out early.
The early queen move is one of the things that makes the Scandinavian different from many other defenses. White can gain time by developing pieces while attacking the queen, so Black has to develop efficiently and avoid moving the queen unnecessarily.
The Scandinavian Defense has several important variations, including the Modern Variation, Classical Variation, and Portuguese Variation. These systems give Black different ways to develop the pieces and create counterplay.
The opening is popular with players who prefer a straightforward approach and don’t mind reaching positions that are different from the usual 1.e4 openings.
Alekhine Defense
The Alekhine Defense is an unusual response to 1.e4 because Black immediately develops the knight instead of occupying the center with a pawn.
The opening starts with:
1. e4 Nf6
Black attacks the pawn on e4 and often encourages White to advance it. After 2. e5, the knight usually moves to d5.
The basic idea is to allow White to gain space and then attack the advanced pawns later. Black does not try to build a large center immediately. Instead, the pieces and pawns are used to put pressure on White’s center.
The opening is named after Alexander Alekhine, who helped establish it as a serious chess defense. It can lead to complicated positions because White has to decide how much space to take and how to protect the center.
Important variations include the Four Pawns Attack, Exchange Variation, and Modern Variation. Each gives the game a different character.
The Alekhine Defense is particularly interesting for players who don’t mind giving their opponent some early space in exchange for active counterplay.
Nimzowitsch Defense
The Nimzowitsch Defense is another less conventional response to 1.e4. Black develops the queen’s knight and puts pressure on the center without immediately playing a central pawn.
It begins with:
1. e4 Nc6
Black’s knight goes to c6 and prepares to challenge White’s central pawns. White can respond with 2. d4, building a strong center, or choose a quieter development plan.
The opening follows a hypermodern idea: instead of occupying the center immediately, Black uses the pieces to control it and plans to attack it later.
The Nimzowitsch Defense is named after Aron Nimzowitsch, one of the important chess thinkers associated with this style of play.
White can often gain more space, but Black gets a flexible position and can take the game into less familiar territory. This makes the opening attractive to players who enjoy surprising their opponents.
Pirc Defense
The Pirc Defense is a flexible response to 1.e4 in which Black allows White to build a strong pawn center before trying to attack it.
The opening begins:
1. e4 d6
Black usually follows with …Nf6 and …g6, preparing to develop the bishop to g7.
Rather than immediately playing …e5, Black allows White to occupy the center. The idea is that the large white pawn center can later become a target.
This gives the Pirc a very different character from more traditional defenses. White usually gets more space, while Black looks for opportunities to undermine that space with pawn breaks and piece pressure.
The most important systems include the Classical System and the Austrian Attack. The Austrian Attack is particularly aggressive and allows White to build an imposing center while preparing for a kingside attack.
The Pirc Defense can suit players who are comfortable defending patiently before looking for counterplay.
Modern Defense
The Modern Defense is based on a simple but flexible idea: Black does not rush to occupy the center and instead develops the kingside bishop through a fianchetto.
A common starting move is:
1. e4 g6
Black normally follows with …Bg7, giving the bishop control over the long diagonal.
White is usually allowed to establish pawns in the center. Black then tries to challenge those pawns rather than immediately matching them.
The Modern Defense can sometimes transpose into positions similar to the Pirc Defense, but it also has its own systems and ideas. Black has considerable freedom in deciding where the other pieces and pawns should go.
The opening has several named systems, including the Averbakh Variation and other setups based on White’s choice of central formation.
The Modern Defense is often chosen by players who like flexible positions and want to avoid committing their central pawns too early.
Old Indian Defense
The Old Indian Defense is a response to 1.d4 in which Black develops the knight to f6 and then supports the center with …d6.
A common sequence is:
1. d4 Nf6 2. c4 d6
Black’s setup is solid and relatively straightforward. Instead of immediately creating the sharp positions associated with some Indian defenses, Black builds a stable position and waits for the right moment to challenge White’s center.
White normally has more space and can develop the pieces naturally. Black’s goal is to maintain a strong structure and look for counterplay as the game develops.
The Old Indian can lead to strategic middlegames where understanding pawn structures is often more important than memorizing long tactical sequences.
It is a useful opening for players who prefer a solid position and want to avoid some of the sharper theory found in other defenses against 1.d4.
Bogo-Indian Defense
The Bogo-Indian Defense is an Indian opening in which Black develops the bishop to b4 and checks the white king.
It commonly begins:
1. d4 Nf6 2. c4 e6 3. Nf3 Bb4+
The check forces White to respond while Black develops a piece. The bishop on b4 also puts pressure on the knight and can influence the center.
One of the main attractions of the Bogo-Indian is its flexibility. Black can choose different setups depending on how White deals with the check.
The resulting positions are often strategic rather than completely tactical, although both sides can create attacking chances if the pieces become active.
The Bogo-Indian is a good example of an opening where Black does not simply try to copy White’s setup. Instead, Black uses piece activity and pressure against the center to create counterplay.

Dutch Defense
The Dutch Defense is one of the more ambitious ways for Black to respond to 1.d4. Black immediately creates an unbalanced position by moving the f-pawn.
The opening begins:
1. d4 f5
The move controls e4 and gives Black the possibility of building an attack on the kingside.
The drawback is that moving the f-pawn also creates some weaknesses around Black’s king. Because of this, the Dutch Defense can become dangerous for both sides if Black does not develop the pieces carefully.
There are several major systems within the Dutch Defense. The Stonewall Dutch uses a strong pawn formation, while the Leningrad Dutch develops the bishop to g7 and produces a more dynamic position.
The Classical Dutch is another important setup and can lead to strategic middlegames with chances for both players.
The Dutch Defense is generally suited to players who want an unbalanced game from the beginning rather than a quiet symmetrical position.
Stonewall Dutch
The Stonewall Dutch is a well-known system within the Dutch Defense. It is named after the solid-looking pawn formation that Black creates in the center.
A typical setup includes pawns on f5, e6, d5, and c6, although the exact position depends on White’s moves.
The pawn structure gives Black control over important central squares and can support a kingside attack. Black often develops the pieces behind this structure and looks for attacking opportunities.
The strength of the Stonewall is its solid structure, but the same pawn formation can also create weaknesses. White may try to attack those weaknesses rather than directly breaking through the center.
The Stonewall Dutch is therefore less about quick tactics and more about understanding where the pieces belong and how to use the pawn structure.
Leningrad Dutch
The Leningrad Dutch is another major system that comes from the Dutch Defense. Compared with the Stonewall, it gives Black a more flexible and dynamic pawn structure.
A typical setup can begin with:
1. d4 f5 2. g3 Nf6 3. Bg2 g6
Black prepares …Bg7, placing the bishop on the long diagonal.
The bishop can become an important attacking piece, especially when Black later challenges White’s central pawns.
The Leningrad Dutch gives Black active possibilities while avoiding the fixed pawn structure of the Stonewall. Black can choose different central breaks depending on how White develops.
This makes the Leningrad an attractive choice for players who want the aggressive character of the Dutch Defense without committing to a completely fixed structure.
Benoni Defense
The Benoni Defense is an ambitious opening in which Black allows White to gain some central space in exchange for active counterplay.
One common route begins:
1. d4 Nf6 2. c4 c5 3. d5 e6
Black challenges White’s central pawn formation and prepares to create an unbalanced position.
After the central exchanges, Black can obtain active piece play and pressure on the queenside. White usually has more space, but Black gets clear targets and attacking chances.
The Benoni is known for creating positions in which both sides have different plans. White often tries to use the central space, while Black looks for activity and counterplay on the queenside.
The Modern Benoni is the best-known version of this opening and has been played by many strong players.
Modern Benoni
The Modern Benoni is a dynamic system that gives Black active counterplay in exchange for allowing White a strong pawn center.
The opening can arise after:
1. d4 Nf6 2. c4 c5 3. d5 e6 4. Nc3 exd5 5. cxd5 d6
The resulting pawn structure is one of the defining features of the Modern Benoni.
White has more central space, but Black has active plans on the queenside. The bishop on g7 can also become powerful along the long diagonal.
Black often tries to create pressure against White’s queenside pawns, while White may use the central space to launch an attack.
Because of these competing plans, the Modern Benoni can produce sharp and highly complicated middlegames.
It is an opening for players who are comfortable accepting an unusual pawn structure in return for active play and clear counterattacking chances.
Nimzo-Indian Defense
The Nimzo-Indian Defense is one of the most respected ways for Black to meet 1.d4.
The opening begins:
1. d4 Nf6 2. c4 e6 3. Nc3 Bb4
Black develops the bishop to b4 and pins the knight on c3.
The idea is not simply to pin the knight. Black is also putting pressure on White’s central setup and can sometimes damage White’s pawn structure by exchanging the bishop for the knight.
The Nimzo-Indian can lead to many different types of positions. Some variations are highly positional, while others can become tactical and aggressive.
Among its important systems are the Sämisch Variation, Rubinstein Variation, and Classical Variation. Each gives White a different way to respond to Black’s setup.
The opening remains popular because it gives Black active piece play without requiring an immediate commitment to a rigid pawn structure. It is also a good example of how chess openings can be based as much on piece placement and long-term plans as on pawn moves.
