What is En Passant?
En passant (French: 'in passing') is a special pawn capture rule. When your opponent advances a pawn two squares from its starting rank, landing it directly beside your own pawn, you may capture it as though it had only moved one square — landing on the square it passed through, not the square it landed on. The right expires immediately: you must capture on that very next move or lose the opportunity forever.
A Brief History
En passant was introduced in the 15th century when the rule allowing pawns to advance two squares on their first move was added. Players felt it was unfair to use the two-square advance to slip past an enemy pawn without risk. En passant was the solution: the pawn can advance two squares, but it cannot evade capture by doing so. The rule has been part of standard chess ever since.
The Three Conditions
Your pawn must be on the 5th rank
As White, your pawn must be on rank 5 (e.g. e5). As Black, your pawn must be on rank 4 (e.g. e4). A pawn that hasn't advanced that far cannot capture en passant.
The opponent's pawn must have just advanced two squares
The two-square advance must have happened on the immediately preceding move — not two moves ago, not three. The timing is strict.
The opponent's pawn must land directly beside yours
The two pawns must be on the same rank on adjacent files after the advance — e.g. White on e5 and Black on d5, or White on e5 and Black on f5.
How It Works — Step by Step
The Critical Moment
Black has just advanced ...d7-d5 in a single move, landing beside White's pawn on e5. This triggers the en passant right — but only for this exact move.
After exd6 e.p.
White's pawn moves diagonally to d6 — and the black pawn on d5 is removed. The capturing pawn lands on d6 (the square the black pawn passed through), not on d5 where it ended up.
One Move Too Late
White played Nf3 instead of capturing. The en passant right on d6 is now gone permanently — the black pawn on d5 is safe. You must capture en passant immediately or lose the chance forever.
A Real Opening: French Advance
In the French Advance (1.e4 e6 2.d4 d5 3.e5), if Black plays ...f7-f5, White has an en passant capture: exf6 e.p. This position appears regularly in real tournament games.
Common Misconceptions
You can do it any time your pawns are side by side
En passant is only legal on the move immediately after the two-square advance. If you miss it, it's gone forever — even if the position looks identical on the next move.
The capturing pawn lands on the captured pawn's square
The capturing pawn lands on the square the enemy pawn passed through (rank 6 for White, rank 3 for Black) — not on the rank where the enemy pawn ended up (rank 5 or rank 4).
It's an optional or house rule
En passant is a mandatory rule of chess, part of the official FIDE Laws of Chess. It applies in all standard games and has done so since the 15th century.

Can you spot it?
It's White's turn. Black just played ...d7-d5. Is there an en passant capture? If so, what is it?
Black's turn to capture
It's Black's turn. White just played d2-d4. Black has a pawn on e4. Is en passant available?
Is en passant available here?
White just played e4-e5 (one square, not two). Black has a pawn on d5. Can Black capture en passant?
En Passant in Your Openings
These openings frequently produce en passant opportunities
French Defense
The French Advance Variation (1.e4 e6 2.d4 d5 3.e5) regularly creates en passant opportunities. If Black plays ...f7-f5 to attack the advanced e5 pawn, White has the option of exf6 e.p. — opening the f-file and removing a central pawn. Many club players on both sides miss this resource.
View opening pageSicilian Defense
In several Sicilian lines, pawn advances on the c, d, and f files create en passant possibilities. Anti-Sicilian systems and the Grand Prix Attack in particular produce side-by-side pawn structures where en passant rights arise. Missing these captures can mean giving up open-file advantages for free.
View opening pageCaro-Kann Defense
The Caro-Kann Advance Variation (1.e4 c6 2.d4 d5 3.e5) mirrors the French pawn structure. After Black's ...c5 break, pawn advances on both sides can produce en passant chances. The locked nature of these positions makes timing everything — missing an en passant can alter the entire strategic character of the game.
View opening pageFamous En Passant Games
One of the most celebrated tactical combinations in early 20th-century chess. Réti's en passant capture was the pivotal move that broke through Tartakower's position, demonstrating that en passant can be a decisive attacking weapon, not merely a defensive technicality.
A strategic masterpiece where an en passant capture opened lines at the critical moment, converting a positional advantage into a winning endgame. This game is studied in many instructional texts as an example of how pawn structure can be transformed by a single well-timed capture.
A high-profile encounter where en passant played a structural role in the resolution of a sharp middlegame. The resulting passed pawn, created by the en passant capture, proved decisive in the endgame.
Common Mistakes
Pitfalls to avoid
The Forgotten Capture
1.e4 d5 2.e5 f5 3.Nf3?!
White misses exf6 e.p. on move 3. After Nf3, Black's f5 pawn is safe. White has given up a free chance to open the f-file, undermine Black's pawn chain, and gain central control. Always check for en passant before playing any other move.
The Decoy Advance
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5?! 6.Nb3 d5!?
Black plays ...d5, inviting exd6 e.p. After exd6, Black recaptures with the queen or a piece and gains excellent development and open lines. Sometimes offering en passant is a deliberate strategic invitation. Always calculate the position after the capture before taking.
Online Chess Confusion
(any position with en passant available) In online chess, en passant doesn't show up as a highlighted capture square in the usual way on most interfaces — you move your pawn diagonally onto the empty square and the engine handles the capture automatically. Many players miss it entirely or don't know to look for it. Train yourself to ask 'Did my opponent just advance a pawn two squares?' before every move.
Tips for Club Players
Before every move, ask yourself: 'Did my opponent just advance a pawn two squares beside mine?' Make it a habit.
En passant always lands on rank 6 (as White) or rank 3 (as Black) — never on the rank where the enemy pawn ended up.
You are never forced to capture en passant — it is always optional, and sometimes ignoring it is the stronger choice.
In online chess, trigger en passant by moving your pawn diagonally onto the empty square — the platform automatically removes the captured pawn.
In over-the-board play, say 'en passant' clearly while making the move to prevent any confusion about which pawn is captured.
En passant notation uses the destination square: if your e5 pawn captures a d5 pawn, write it as exd6 (not exd5).
Frequently Asked Questions
Everything you need to know about en passant
En passant is a special pawn capture. When your opponent advances a pawn two squares from its starting rank, landing it beside your own pawn on the 5th rank (4th rank for Black), you can capture it as though it had only moved one square. Your capturing pawn lands on the square the enemy pawn passed through. The right lasts exactly one move.
Only on the very next move after the two-square pawn advance. Three conditions must all be true: your pawn is on the 5th rank (4th for Black), the opponent's pawn just advanced two squares in the previous move, and it landed directly beside your pawn on an adjacent file. If you play any other move first, the en passant right is gone permanently.
The capturing pawn lands on the square the enemy pawn passed through — rank 6 for White, rank 3 for Black. It does NOT land on the rank where the enemy pawn ended up. The enemy pawn (which ended up on rank 5 or 4) is still removed from the board.
No. En passant is always optional. You can choose to capture or ignore the opportunity entirely. Sometimes it's strategically better not to capture — for example, if taking would open lines toward your own king.
