English Opening
Encyclopedia
In chess
, the English Opening is the opening
where White begins:
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 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
, and Garry Kasparov
all employed it during their world championship matches. Bobby Fischer
created a stir when he switched to it from his hitherto almost universal 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
.
Also white can play 2.Nf3. Then black may play 2...e6 for English (A13, see 1.c4 Nf6 2.Nf3 e6). This can lead to Queen's Gambit Declined
(D37), Queen's Indian (E12), or Symmetrical Variation (A30). Or black may play 2...g6 for English (A15, see 1.c4 Nf6 2.Nf3 g6). This can lead to King's Indian Defense (E60), King's Indian, Orthodox (E94), King's Indian (E92), or English (A15).
Also white can play 2.Nc3. Then black may play 2...e5 for English (A28, see 1.c4 Nf6 2.Nc3 e5). This can lead to English (A28), Old Indian, Ukrainian Variation, 4.Nf3 (A54), or English (A22). Or black may play 2...e6 for English (A17, see 1.c4 Nf6 2.Nc3 e6). This can lead to Nimzo-Indian, Classical (E32), Queen's Gambit Declined (D35), Symmetrical Variation (A30), or Queen's Gambit Declined (D37).
Also white can play 2.g3. Then black may play 2...Nf6 for English (A20, see 1.c4 e5 2.g3 Nf6). This can lead to English (A22) or English (A20). Or black may play 2...Nc6 for English (A25, see 1.c4 e5 2.g3 Nc6). This can lead to English (A25), English (A22), or English (A20).
. Then black may play 2...Nf6 (see 1.d4 Nf6 2.c4 e6), or black may play 2...d5 (see 1.d4 d5 2.c4 e6).
Also white can play 2.Nf3. Then black may play 2...Nf6 (given above). Or black may play 2...d5 for English (A13, see 1.c4 e6 2.Nf3 d5). This can lead to Queen's Gambit Declined
(D37), Queen's Gambit Declined (D30), or English (A13).
Also white can play 2.Nc3. Then black may play 2...Nf6 (given above). Or black may play 2...d5 for Queen's Gambit Declined (D31, see 1.c4 e6 2.Nc3 d5). This can lead to Queen's Gambit Declined (D35) or Queen's Gambit Declined (D31).
(E10), or Symmetrical Variation, Benoni Formation (A31). Or black may play 2...Nc6 for Réti Opening
(A04, see 1.Nf3 c5 2.c4 Nc6). This can lead to Symmetrical Variation (A35), Reti Opening (A04), or Symmetrical Variation (A33).
Also white can play 2.Nc3. Then black may play 2...Nf6 for Symmetrical Variation (A34, see 1.c4 c5 2.Nc3 Nf6). This can lead to Symmetrical Variation (A30), Symmetrical Variation (A35), or Symmetrical Variation (A34). Or black may play 2...Nc6 for English (A36, see 1.c4 c5 2.Nc3 Nc6). This can lead to Symmetrical Variation (A35), Reti Opening (A04), English (A36), or English (A34).
. Then black may play 2...Nf6 (see 1.d4 Nf6 2.c4 g6), or black may play 2...Bg7 (see 1.d4 g6 2.c4 Bg7).
Also white can play 2.Nc3. Then black may play 2...Nf6 for English (A16, see 1.c4 Nf6 2.Nc3 g6). This can lead to King's Indian Defense (E97), Grünfeld Defense (D85), King's Indian (E95), or English (A15). Or black may play 2...Bg7 for English (A10, see 1.c4 g6 2.Nc3 Bg7). This can lead to King's Indian Defense (E97), Modern Defense, Averbakh System (A42), English (A16), or English (A36).
Also white can play 2.Nf3. Then black may play 2...Nf6 (given above). Or black may play 2...c5 for Réti Opening
(A04, see 1.c4 c5 2.Nf3 g6). This can lead to Reti Opening (A04) or Sicilian, Accelerated Fianchetto (B36).
Also white can play 2.d4. Then black may play 2...d5 for Slav Defense
(D10, see 1.d4 d5 2.c4 c6). This can lead to Slav Defense (D15), Queen's Gambit Declined
(D30), Slav Defense (D10), or Queen's Gambit Declined (D31). Or black may play 2...Nf6 for Slav Defense (D15, see 1.d4 Nf6 2.c4 c6). This can lead to Slav Defense (D15) or Slav Defense (D10).
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 Reti 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.
Another broad category of defence Black can choose against the English Opening is called the Reverse(d) Sicilian (classified A20s in ECO), which is 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 Reverse Sicilian.
The third broad category are the non-...e5 and non-...c5 responses, classified A10s 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
Opening theoreticians who write on the English Opening break the opening down into three broad categories, generally determined by Black, who selects one of three types of defensive setups. These include the Symmetrical Defense (classified A30s 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 playing a delayed ...c5, and in fact often does. For example, 1.c4 Nf6 2.Nc3 (or 2.Nf3) c5 is a Symmetrical Defense even though Black played ...c5 on move two.Another broad category of defence Black can choose against the English Opening is called the Reverse(d) Sicilian (classified A20s in ECO), which is 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 Reverse Sicilian.
The third broad category are the non-...e5 and non-...c5 responses, classified A10s 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:
- 1...Nf6 The most common response to 1.c4, often played in hopes of getting an Indian Defence. However, more than half the time after playing this first move, Black subsequently elects to transpose into either a Symmetrical Defense with ...c5, or a Reversed Sicilian with ...e5.
- 1...e5 White has black's position in the Sicilian but with a tempoTempo (chess)In chess, tempo refers to a "turn" or single move. When a player achieves a desired result in one fewer move, he "gains a tempo" and conversely when he takes one more move than necessary he "loses a tempo"...
