Benko Gambit Declined Pseudo-Samisch (1.d4 Nf6 2.c4 c5 3.d5 b5 4.f3 / 1.d4 Nf6 2.c4 c5 3.d5) Chess Puzzles

Benko Gambit Declined Pseudo-Samisch is a Benko Gambit Declined line where Black’s setup aims for a flexible queenside play while White adopts a “Samisch-like” kingside structure (often with an early f-pawn advance and a strong pawn chain). The defining feature is not a single universal move order, but the resulting pawn/piece placement that resembles Samisch structures even though the Benko Gambit was declined. Because this is an Lichess-labeled sub-branch, the exact move sequence can vary by transposition, and the precise “defining move” is not consistently documented across sources.
