Bird Opening Horsefly Defense En Passant in Chess

In the Bird Opening Horsefly Defense, White often plays an early f-pawn or e-pawn thrust to build space while Black aims for active counterplay. The “En Passant” motif appears when Black’s pawn move creates an en-passant capture right after White advances a pawn two squares, allowing Black to remove the advanced pawn and disrupt White’s tempo. The defining feature is the tactical timing: the en-passant right is created by a specific two-square pawn move and must be taken immediately.
