Reti Opening Reversed Blumenfeld Gambit (1.Nf3 d5 2.c4 d4 3.e3 c5 4.b4 / 1.Nf3 d5 2.c4 d4 3.e3) Chess Puzzles

The reti opening reversed blumenfeld gambit is a Reti-family opening where the “Blumenfeld” pawn sacrifice structure appears in a reversed move order, typically aiming to provoke ...c5 and then challenge Black’s queenside pawn setup. For an intermediate player, the defining feature is that White’s early queenside pawn thrusts and piece placement try to obtain activity while accepting (or forcing) a temporary pawn imbalance rather than playing a straightforward Reti setup.
