English Opening
1.c4: a flexible flank opening with long-term pressure on the light squares. You play White. The English Opening is named after Howard Staunton, who played 1.c4 in his 1843 match against Saint-Amant. White controls d5 from the flank and often expands on the queenside. Botvinnik, Kasparov and Carlsen all used it as a main weapon.
