A flank opening, it is the fourth most popular and, according to various databases, anywhere from one of the two most successful to the fourth most successful of White's twenty possible first moves. White begins the fight for the centre by staking a claim to the d5 square from the wing, in hypermodern style. Although many lines of the English have a distinct character, the opening is often used as a transpositional device in much the same way as 1.Nf3 – to avoid such highly regarded responses to 1.d4 as the Nimzo–Indian and Grünfeld defences, and is considered reliable and flexible.
The English derives its name from the English (unofficial) world champion, Howard Staunton, who played it during his 1843 match with Saint-Amant and at London 1851, the first international tournament. It did not inspire Staunton's contemporaries, and only caught on in the twentieth century. It is now recognised as a solid opening that may be used to reach both classical and hypermodern positions. Mikhail Botvinnik, Tigran Petrosian, Anatoly Karpov, Garry Kasparov and Magnus Carlsen employed it during their world championship matches. Bobby Fischer created a stir when he switched to it from his customary 1.e4 late in his career, employing it against Lev Polugaevsky and Oscar Panno at the Palma de Mallorca Interzonal in 1970 and in his 1972 world championship match against Boris Spassky.
Taxonomy
Opening theoreticians who write on the English Opening break the opening down into three broad categories, generally determined by Black's choice of defensive setups.
Symmetrical Defense: 1...c5
The Symmetrical Defense (classified A30–39 in ECO), which is 1...c5, and is so named because both of the c-pawns are advanced two squares, maintaining symmetry. Note that Black can reach the Symmetrical Defense through many move orders by deferring ...c5, and often does. For example, 1.c4 Nf6 2.Nc3 (or 2.Nf3) c5 is a Symmetrical Defense even though Black played ...Nf6 before ...c5.
There are several types of positions that can arise from the Symmetrical Defense. Among the ideas are:
Either player may make an early break in the centre with the d-pawn.
Reversed Sicilian: 1...e5
The Reversed Sicilian (classified A20–29 in ECO) is another broad category of defence, introduced by the response 1...e5. Note again, that Black can delay playing ...e5, for example 1.c4 Nf6 2.Nc3 Nc6 3.Nf3 e5 whereupon even though ...e5 has been delayed, once it is played the defence is classified as a Reversed Sicilian.
Other variations
The third broad category are the non-...e5 and non-...c5 responses, classified A10–19 in ECO. Most often these defences consist of ...Nf6, ...e6, and ...d5 or ...Bb4 systemic responses by Black, or a Slav-like system consisting of ...c6 and ...d5, a direct King's Indian Defense setup with ...Nf6, ...g6, ...Bg7, ...0-0, after which ...c5 and ...e5 are eschewed, or 1...f5, which usually transposes to a Dutch Defense once White plays d4. All irregular responses such as 1...b6 and 1...g5 are also lumped into this third broad category.
Common responses include:
Transposition potential
If White plays an early d4, the game will usually transpose into either the Queen's Gambit or an Indian Defence. For example, after 1.c4 Nf6 2.Nc3 g6 3.d4 d5 the game has transposed into the Grünfeld Defence, usually reached by the move order 1.d4 Nf6 2.c4 g6 3.Nc3 d5.
Note, however, that White can also play 1.c4 Nf6 2.Nc3 g6 3.e4, making it impossible for Black to reach a Grünfeld, instead more or less forcing him into lines of the King's Indian Defence with 3...d6. Black also cannot force a Grünfeld with 1.c4 Nf6 2.Nc3 d5, since White can deviate with 3.cxd5 Nxd5 4.g3, a line played several times by Mikhail Botvinnik in 1958, in his final match for the world championship with Vasily Smyslov.
Instead of playing an early d4, White can also play Nf3 and fianchetto the king's bishop (g3 and Bg2), transposing into a Réti Opening.
Also, after 1.c4 c6, White can transpose into the Polish Opening, Outflank Variation, by playing 2.b4!?, which can be used as a surprise weapon if Black does not know very much about the Polish Opening.
The many different transpositional possibilities available to White make the English a slippery opening for Black to defend against, and make it necessary for him to consider carefully what move order to employ. For instance, if Black would like to play a Queen's Gambit Declined, the most accurate move order to do so is 1...e6 2.d4 d5. (Of course, White can again play the Reti instead with 2.Nf3 d5 3.b3.) If Black plays instead 1...Nf6 2.Nc3 e6, White can avoid the QGD by playing 3.e4, the Flohr-Mikenas Attack.
ECO
The Encyclopaedia of Chess Openings has classified the English Opening under the codes A10 through A39:
Depiction in cinema
The English Opening is used by Professor Moriarty in the film Sherlock Holmes: A Game of Shadows as he and Holmes discuss their competing plans over a game of chess. Both Holmes and Moriarty eventually play the final moves blindfolded by citing out the last moves in descriptive notation (rather than algebraic, as the former was contemporary in the late 19th century), ending in Holmes checkmating Moriarty, just as Watson foils Moriarty's plans.
The English Opening is also used in Pawn Sacrifice by Bobby Fischer in the climactic game six of the 1972 World Chess Championship against Boris Spassky.
