In chess, the English Opening is the opening where White plays

1. c4

A flank opening, it is the fourth most popular opening.[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.

The English derives its name from the English (unofficial) world champion, Howard Staunton, who played it during his 1843 match with Saint-Amant. It fell out of favor (the opening was notably disdained by Morphy), but 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.

[edit] Transpositional 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, 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.[3]

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.

[edit] 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.[4] 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[5]
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 ...f6 and ...Qh4 will be played. Anthony Miles and Jonathan Speelman used this opening successfully in recent years.
