Latvian Gambit Fraser Defense En Passant in Chess

The Latvian Gambit Fraser Defense En Passant is a tactical motif arising from the Latvian Gambit line where Black’s pawn advance creates an en-passant capture for White. The defining feature is the moment White can capture a pawn “as if” it had moved only one square, immediately after Black’s two-square pawn move. In practice, it’s a concrete refutation resource tied to the pawn structure and tempo of the Fraser Defense.
