RETI (1889-1929) During and after World War I there emerged a group of young players who attempted to break completely with accepted opinion. Foremost among them was Reti. Instead of occupying the centre with pawns these hypermoderns, with Reti as their leader, preferred to control the central territory by the action of their pieces. They developed their Bishops on the flanks and held back the centre pawns as long as possible. In his innovations Reti eventually went too far. He overpressed his theories, as inexperienced players sometimes do, and was often the victim of practical difficulties} 1. Nf3 {Zukertort also frequently opened with this Knight move, but the system White used here was worked out by Reti, and is quite rightly known as Reti's opening} 1... d5 2. g3 Nf6 3.

The centre is under control by White's pieces - not pawns. Note that White has made no automatic developing moves; he has not yet castled. The hypermodern player does this only after some sophisticated preliminary strategical skirmishing} 11... b6 12. a3 Bb7 13. Bb2 bxa3 14. Rxa3 Qc7 15.
