Reti Opening Advance Variation Intermediate (1.Nf3 d5 2.c4 d4 / 1.Nf3 d5 2.c4 d4 3.b4 c5) Chess Puzzles

The reti opening advance variation intermediate usually refers to a Réti setup where White delays an early central pawn commitment and then meets Black’s ...d5 with an advance-based structure, often after 1.Nf3 and a later c4 or g3 setup. For an intermediate player, the defining feature is not a forced move order but the moment White uses an advance-style central claim to challenge Black’s space while keeping the Réti’s flexible piece placement.
