ParentFlank opening

In chess, the English Opening is the opening where White begins 1.c4.

A flank opening, it is the fourth most popular of the twenty possible first moves.[1][2] White begins the fight for the center by staking a claim to the d5 square. Although many lines of the English have a distinct character, it often transposes into other openings and is considered flexible.

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.[3] It did not inspire Staunton's contemporaries, and only caught on in the twentieth century.[4] It is now recognized as a solid opening that may be used to reach both classical and hypermodern positions. Botvinnik, Karpov, and Kasparov all employed it during their world championship matches. Bobby Fischer created a stir when he switched to it from the King's Pawn against Boris Spassky in 1972.

Transpositional Potential

1...Nf6

White can play 2.d4, thereby transposing to the Indian defence, which is usually reached by 1.d4 Nf6 2.c4. Then black may play 2...e6 (see 1.d4 Nf6 2.c4 e6), or black may play 2...g6 (see 1.d4 Nf6 2.c4 g6). 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).

1...e5

White can play 2.Nc3. Then black may play 2...Nf6 (given above). Or black may play 2...Nc6 for English (A25, see 1.c4 e5 2.Nc3 Nc6). This can lead to English (A25), English (A22), or English (A20). 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).

1...e6

White can play 2.d4, which is usually reached by 1.d4 e6 2. c4 so see Queen's Pawn Game. 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).

1...c5

White can play 2.Nf3. Then black may play 2...Nf6 for Symmetrical Variation (A30, see 1.Nf3 c5 2.c4 Nf6). This can lead to Symmetrical Variation (A30), Symmetrical Variation (A35), Queen's Pawn Game (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).

1...g6

White can play 2.d4, which is usually reached by 1.d4 g6 2.c4 so see Queen's Pawn Game. 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).

1...c6

White can play 2.e4, which is usually reached by 1.e4 c6 2.c4 so see Caro-Kann Defense. Then black may play 2...d5 (see 1.e4 c6 2.c4 d5), or black may play 2...e5 (see 1.e4 c6 2.c4 e5). 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, and instead more or less forcing him to defend a 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.

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.[5]

The many different transpositional possibilities available to White make the English a slippery opening for Black to defend against, and make it advisable 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 instead.

Common responses

Common responses include:[1]

1...Nf6 hopes to get an Indian Defence.
1...e5 White has black's position in the Sicilian but with a tempo up. This is often called the reverse-Sicilian.[6] Bruce Leverett, writing the English chapter in MCO14, stated, "It is natural to treat the English as a Sicilian reversed, but the results are often surprising--main lines in the Sicilian Defense correspond to obscure side variations in the English, and vice versa."
1...e6 (Can lead to a Queen's Gambit Declined after 2.Nc3 d5 3.d4, but White usually prefers 2.Nf3 or 2.g3)
1...c5 (the Symmetrical Variation) including attempts to try the Hedgehog system[7]
1...g6 leads to a kind of Modern Defense or after d6 and Nf6 to a kind of King's Indian Defence.
1...c6 (Can lead to a Slav Defence after 2.d4 d5, but White usually prefers a Caro-Kann Defence with 2.e4 d5, or a Reti Opening after 2.Nf3 d5).
1...b6 The English Defence. This setup involves the fianchetto of the queenside bishop and 2...e6. Often Black will attack the center with ...f5 and/or ...Qh4. The English grandmasters Anthony Miles and Jonathan Speelman used this opening successfully.
