Board Position
This flank opening - actually an early gambit in what is otherwise sometimes called the Zukertort opening 1.Kt-KB3(f3) - is named after Richard Réti (1889-1929), a Czech mathematician and physicist who was one of the founders of the Hypermodern School and who left many writings on the game.
The aim of the opening is control of the centre without occupation, in the hope that Black will set up a rigid pawn structure that will be vulnerable to attack. White's usual gambit move 2..P-QB4(c4) is shown left. Requiring deep positional judgements, the opening is rarely seen outside master chess!
Avoiding the centre, the Reti tends to use a fianchetto, often becoming a Catalan or a Barcza system.
