Four Knights Game En Passant in Chess

In the Four Knights Game, the “Four Knights Game En Passant” motif refers to the tactical possibility of capturing a pawn en passant after a specific two-square pawn advance. It typically emerges from the Four Knights opening’s early pawn moves, where one side’s pawn can pass a square that becomes capturable immediately on the next move. The defining feature is that the en-passant capture is only legal right away, often creating a tempo gain or opening lines.
