Editing French Defence (section)

==Early deviations for Black==
Although 2...d5 is the most consistent move after 1.e4 e6 2.d4, Black occasionally plays other moves. Chief among them is 2...c5, the '''Franco-Benoni Defence''', so-called because it features the c7–c5 push characteristic of the [[Benoni Defence]]. White may continue 3.d5, when play can transpose into the Benoni, though White has extra options since c2–c4 is not mandated. 3.Nf3, transposing into a normal [[Sicilian Defence]], and 3.c3, transposing into a line of the [[Sicilian Defence, Alapin Variation|Alapin Sicilian]] (usually arrived at after 1.e4 c5 2.c3 e6 3.d4) are also common. Play may also lead back to the French; for example, 1.e4 e6 2.d4 c5 3.c3 d5 4.e5 transposes into the [[#Advance Variation|Advance Variation]]. 

Another move is 2...b6, which transposes into [[Owen's Defence]] or the [[English Defence]]. Also possible is 2...f5, the '''Franco-Hiva Gambit''', but this is regarded as dubious.<ref>Watson, John: [https://books.google.com/books?id=fidBCwAAQBAJ&dq=%221.e4+e6+2.d4+f5%22&pg=PA3 Taming Wild Chess Openings] p. 67</ref>

2...d6 is a version of the '''Lengfellner System''', in which Black begins the game with e7–e6 and d7–d6 regardless of the opponent's moves. (White can also play the Lengfellner System by opening e2–e3 and d2–d3). The Lengfellner System is usually adopted by players who wish to reach a stable position while avoiding opening theory.<ref>{{cite book |last1=Hooper |first1=David |author-link1=David Vincent Hooper |last2=Whyld |first2=Kenneth |author-link2=Kenneth Whyld |title=The Oxford Companion to Chess |publisher=[[Oxford University Press]] |edition=2nd |year=1996 |orig-year=First pub. 1992 |contribution=Lengfellner System |page=222 |isbn=978-0-19-280049-7|title-link=The Oxford Companion to Chess }}</ref>
