Benko Gambit Declined Main Line (1.d4 Nf6 2.c4 c5 3.d5 b5 4.Nf3 / 1.d4 Nf6 2.c4 c5 3.d5) Chess Puzzles

The benko gambit declined main line is a Benko Gambit variation where Black offers the queenside pawn sacrifice, but White declines to take it and instead keeps a more solid center. In the “main line” form, the defining feature is that White’s choice is to not accept the gambit pawn immediately, leading to a position where Black’s compensation comes mainly from pressure and activity rather than a direct extra pawn. I don’t have a reliably documented, specific move-by-move sequence for the exact Lichess “Benko_Gambit_Declined_Main_Line” order from memory, so I can’t safely list the precise move
