Réti Opening
1.Nf3 and 2.c4: control the centre from the flanks. You play White. Richard Réti, one of the hypermoderns, used 1.Nf3 and 2.c4 to control the centre from the flanks. His win with it against Capablanca in New York 1924 ended Capablanca's eight-year unbeaten run. The Réti stays flexible and can transpose into many other openings.
