Indian Defense Budapest Defense En Passant in Chess

In the Indian Defense Budapest Defense En Passant motif, Black uses the Budapest structure (often via ...Nf6 and ...e5) and creates a moment where White’s pawn advances two squares and can be captured en passant. The defining feature is the pawn on the 5th rank that becomes capturable immediately after the double-step, turning a “normal” pawn structure into a tactical win of tempo or material.
