 In fact, the KIA is probably most often reached after 1.e4 when White uses it to respond to a Black attempt to play one of the semi-open games such as the Caro–Kann, French, or Sicilian, or even the open games which usually come after 1.e4 e5.Its greatest appeal may be that by adopting a set pattern of development, White can avoid the large amount of opening study required to prepare to meet the many different possible Black replies to 1.e4.The English Opening (1.c4) also frequently transposes into a d4 opening, but it can take on independent character as well including the Symmetrical Variation (1.c4 c5) and the Reversed Sicilian (1.c4 e5).
