Indian Defense Pyrenees Gambit (1.d4 Nf6 2.c4 b5) Chess Puzzles

The “Indian Defense Pyrenees Gambit” is an Indian Defense sideline where Black offers material early to gain initiative against White’s center. I don’t have a reliably documented, standard defining move order for this exact named gambit (it’s obscure and transposes across sources), but the concept is typically recognized by a Pyrenees-style early pawn sacrifice in an Indian structure, aiming for rapid piece activity and pressure on the dark squares.
