Catalan Opening En Passant in Chess

“Catalan Opening En Passant” refers to the en-passant capture that can arise from pawn structures typical of the Catalan Opening (often after White plays d4/c4 and develops pieces to pressure the center). The defining feature is a pawn on the 5th rank that can capture en passant immediately after the opponent advances a neighboring pawn two squares. In practice, you’re looking for the exact timing window created by a Catalan-style pawn break that opens an en-passant target.
