Polish Opening Czech Defense En Passant in Chess

In the Polish Opening’s Czech Defense, the “en passant” motif appears when Black advances a pawn two squares and White has a pawn on the correct adjacent file to capture it immediately. The defining feature is the timing: after the double-step, White must have a pawn that could capture that pawn as if it had moved only one square. This creates a tactical moment tied to the specific pawn structure reached in the Polish Opening Czech Defense.
