White starts with 1.c4, controlling d5 from the side. It is flexible and often leads to slow, strategic games.
White often fianchettoes with g3 and Bg2 to aim the bishop down the long diagonal.
Against 1...e5 it is like a Sicilian with colours reversed and an extra tempo for White.
White fights on the queenside with b4-b5 and the open c-file.
