Have you ever seen a pawn capture another pawn sideways, like it came out of nowhere? If so, you probably just saw en passant, one of the most confusing chess rules for new players.
The name is French and means "in passing". Think of it like a special power your pawn has to stop an opponent's pawn from using its first two-step move to sneak by and avoid a fight.
Understanding This Unique Chess Rule
This weird rule wasn't always in chess. It was added around the 1800s to fix a problem that popped up when pawns were first allowed to move two squares at once. Before that, a pawn could just zoom past an enemy pawn next to it, which didn't seem very fair. En passant made things even again.
If you want to learn more about how chess rules have changed over time, the US Chess Federation has some cool info on the game's history.
So, when can you actually make this move? It's not a free-for-all. There are three strict rules that all have to be met. If even one isn't true, you can't do it.
Quick Checklist for an En Passant Move
Use this simple checklist to see if you can make an en passant capture. All three things must be true.
| Condition | Yes / No |
|---|---|
| Is your pawn on its fifth row? | |
| Did the other player's pawn just jump two squares to land beside yours? | |
| Is it your very next turn, with no other moves made in between? |
If you can say "yes" to all three, great! You can choose to capture en passant.
But here’s the tricky part: it's a "now or never" chance. If you make a different move instead, you lose the right to make that specific en passant capture forever. This adds a really cool tactical twist to the game and can lead to surprise attacks that change everything. Let's look at these rules a little closer.
The Three Conditions for an En Passant Capture
The special en passant move feels a bit like a hidden cheat code, but it has very strict rules. It can only happen when three specific things line up perfectly. Think of them as a three-part checklist you have to go through before you can pull off this cool capture.
Let's break them down one by one, so you'll always know when you have the chance.
Rule 1: The Capturing Pawn's Position
First, your pawn has to be in the right spot. For an en passant capture to even be possible, your pawn must already be on its fifth row.
If you're playing as White, this is the row numbered '5'. If you're playing as Black, it’s row '4'. Your pawn needs to have already marched halfway across the board to get into this special attack zone.
Think of your pawn as a guard standing deep in enemy territory. It's moved far enough to control an important area and is now watching the columns next to it for any pawns trying to sneak by. Getting your pawn to this row is the first piece of the puzzle.
Rule 2: The Opponent's Pawn's Move
Second, the other player's pawn has to make a very specific move. The enemy pawn must have just moved two squares forward from its starting spot.
This is what triggers the move. Pawns have that special one-time ability to jump two squares on their very first move. When your opponent's pawn uses this double-step and lands right next to your pawn (which is already waiting on its fifth row), the conditions for en passant are suddenly met.
This is the only way an en passant capture can happen. If the opponent's pawn moves just one square, or if any other piece moves, this chance doesn't exist. It's all about that first two-square jump.
This chart shows the simple checklist your brain should use to make sure an en passant is legal.
As you can see, the move is only possible when the pawn's position, the opponent's action, and the timing all line up perfectly.
Rule 3: The Timing of the Capture
Finally—and this is the one many players forget—the timing has to be perfect. You have to make the en passant capture on your very next turn.
This is a "now or never" move. If you decide to move another piece, even for just one turn, you lose the right to capture that pawn en passant forever. The opportunity is gone in a flash.
This is what makes the rule so tricky and fun. You can't wait to see if it becomes a better move later. You have to decide right away. This rule adds a real layer of pressure, forcing players to stay sharp and take the chance when it appears.
So, to review the three main conditions:
- Your Pawn: Must be on its fifth row (row 5 for White, row 4 for Black).
- Opponent's Pawn: Must move two squares from its starting square, landing beside your pawn.
- Your Move: You must capture right away on your very next turn.
If you can check all three of those boxes, you're good to go.
Reading about a rule is one thing, but seeing it happen is the best way to really get it. The en passant in chess rules can feel a little confusing until you see the pieces move, so let’s walk through it together on the board.
We’ll break down two clear examples, one for White and one for Black, showing you exactly what happens.
One of the biggest questions people have is where the capturing pawn actually lands. Does it hop behind the other pawn? Does it land on the same square? Let's clear that up right now.
Your pawn moves diagonally to the empty square behind the pawn it’s capturing—exactly where it would have landed if the enemy pawn had only moved one step forward.
Example 1: White Captures a Black Pawn
Alright, let's set up the board. Imagine you're playing White and your pawn has bravely marched all the way to the e5 square. It’s sitting on its fifth row, which means the first rule for en passant is already met. Now, it's Black's turn.
Your opponent decides to push their d-pawn, which is still on its starting square. They move it two squares forward, from d7 all the way to d5, landing it right beside your pawn on e5. This two-square jump is the trigger—now you have the chance to capture en passant!
Here’s how it works:
- White's Pawn: Sits on e5.
- Black's Move: The d-pawn jumps from d7 to d5.
- Your Chance: You can only do this on your very next move.
To make the capture, you move your pawn from e5 diagonally forward to the d6 square. The moment your pawn lands on d6, you reach over and remove your opponent's pawn from d5. The Black pawn is captured "in passing," as if it only tried to move one square to d6.
When you write this down, the code is exd6 e.p. The 'e' tells you which column your pawn came from, 'x' means it's a capture, 'd6' is the square it lands on, and 'e.p.' is just short for en passant.
Example 2: Black Captures a White Pawn
Now, let's flip the board and look at it from Black's side. It's the exact same idea, just for the other team.
In this game, you're playing as Black. Your pawn has moved to the c4 square. For Black, the "fifth row" is actually the 4th row, so your pawn is in the perfect spot to make an en passant capture.
Your opponent (White) has a pawn on its starting square at b2. They decide to push it two squares forward to b4, placing it right next to your pawn on c4. Just like before, the conditions are now perfect for you to make the move.
This special pawn capture is a powerful part of the en passant in chess rules. It was added to stop pawns from using their two-square starting move to just sneak past danger without a fight, which keeps the game fair.
Let’s see how Black's capture works:
- Black's Pawn: Is waiting on the c4 square.
- White's Move: The pawn on b2 jumps two squares to b4.
- Your Capture: You have to do it now, on your very next turn.
To finish the move, you will slide your pawn from c4 diagonally to the b3 square. As soon as your pawn lands on b3, the White pawn on b4 is taken off the board. You’ve successfully caught it as it "passed" through the b3 square.
The code for this move is cxb3 e.p. The 'c' is the column your pawn started on, 'x' shows it's a capture, and 'b3' is the square it lands on.
Once you picture these two situations, you can see the rule is the same for both players. The main thing to remember is that your pawn always moves to the square the enemy pawn would have landed on if it had only moved one step.
Common En Passant Mistakes to Avoid
Every chess player, and I mean every player, gets confused by the en passant rule at first. Let's be honest, it feels a little weird, so it’s super easy to get it wrong. But don’t worry, once you know the common mistakes, you’ll avoid them like a pro.
Let's look at the most common slip-ups I see beginners make, so you can skip them in your own games.
Forgetting the "Now or Never" Rule
This is the big one. It's the most common mistake by far. A player sees the chance to capture en passant, but thinks, "Hmm, I'll make this other move first and get that pawn later."
Nope. You can't do that. The en passant capture is a quick chance—a one-time offer. It's available only on the move right after your opponent's pawn moves two squares. If you play anything else, that specific en passant chance is gone forever.
Pro Tip: Think of en passant like a reflex. The opportunity flashes, and if you don't act right away, the moment is lost. This "use it or lose it" rule is what makes it so unique.
Trying to Capture a Pawn That Moved One Square
Another common mistake is trying to use the en passant rule on a pawn that only moved one square forward. It's an easy mix-up, but remember the whole point of this rule: it exists to stop a pawn from using its first two-square "sprint" to sneak past an enemy pawn.
The rule only starts when an opponent's pawn jumps two squares from its starting row to land right beside your pawn. If it only moves forward one square, only a normal diagonal capture is possible—no en passant allowed.
Common Errors at a Glance
To make it super clear, here are the top three mistakes in short:
- Waiting Too Long: You see the chance but try to capture en passant a turn or two later. Fix: You have to capture right away.
- Wrong Pawn Move: You think you can capture a pawn that only moved one square. Fix: The enemy pawn must have jumped two squares from its starting spot.
- Wrong Pawn Position: You try to capture when your pawn isn't on its fifth row (or fourth row for Black). Fix: Your pawn has to be in the right attack zone for the move to be legal.
Because en passant needs such a specific setup on the board, it's actually pretty rare in chess. Studies of top-level games show the move happens in less than 1% of all pawn captures. This rarity makes it even more important to know the rules perfectly for when that moment finally comes.

By avoiding these simple mistakes, you'll be confidently using one of the trickiest rules in chess. Not only will you play correctly, but you'll also be able to see when your opponents get it wrong.
Why This Special Rule Is Important for Strategy
Alright, so you know the "what" and "how" of en passant. But have you ever stopped to think why this weird little rule even exists? It’s not just some random thing thrown in to make chess more confusing; it plays a big part in keeping the game fair and fun to play.
The main job of en passant is to stop a pawn from using its special two-square dash to sneak past an enemy pawn without any risk. Think of your pawn as a guard, patiently controlling a key square. If an enemy pawn could just sprint past that guard in one go, it would feel a bit like cheating, right?
Keeping the Game Fair
The en passant rule makes sure that pawns have to deal with the results of their moves. Without it, a pawn could just cruise past an opposing pawn that was in the perfect spot to capture it. This rule was added to chess to fix this problem after the two-square pawn move was introduced. It keeps the game exciting and is the reason we see so many open columns and pawn attacks.
This rule is a key part of what makes chess so balanced. It forces pawns to interact with each other, which is super important for creating weaknesses and finding chances to attack. Understanding how pawns work together is a huge part of getting better at the game. If you really want to learn more about this, you might find our book review on rock-solid pawn structures helpful.
Creating Tactical Opportunities
But en passant is more than just a rule for fairness—it's a sharp weapon. Knowing when to use an en passant capture can completely change the game.
En passant isn't just about capturing a pawn; it's about what that capture does. It can open a column for your rook, clear a diagonal for your bishop, or even set up a clever check.
Here are a few ways you can use it to your advantage:
- Opening Lines: An en passant capture can suddenly crack open a column for your rook or queen, letting you launch a surprise attack on your opponent’s king or a key piece.
- Creating Pawn Breaks: You can use it to smash through your opponent's line of pawns, making their position weaker and creating targets to attack later.
- Controlling the Center: A smart en passant can get rid of a key central pawn, giving you more control over the most important part of the board.
Thinking of en passant as just a weird, rare rule is a classic beginner's mistake. A strong player sees it as another tool in their toolbox—one that can create unexpected problems for their opponent and keep the game interesting.
Got Questions About En Passant?
Even after you get the hang of it, en passant can still be a little tricky. It's such a unique move that it’s normal to have questions. Let’s go over some of the most common ones I hear from players.
This quick Q&A should clear up any last doubts and help you use this rule without worry.
Do I Have to Capture En Passant?
Nope, you are never forced to make an en passant capture. Just like any other capture, it’s a choice. It's your job to figure out if it's the best move in your situation.
Sometimes, capturing is a great move. Other times, it might mess up your pawn setup, or you might just have a much better move to make. The key thing to remember is that you only get one chance—it has to be done on the very next turn after your opponent's pawn makes its two-square jump.
Think of it this way: The game is offering you a special chance. It's up to you, the player, to decide if that chance actually helps you win. Always think about your options before you make the capture.
Can an En Passant Capture Give Check or Checkmate?
Yes, absolutely! An en passant capture can be a deadly and often surprising attack. When your pawn takes the opponent's pawn, it lands on a new square. That simple move can suddenly open up a line of attack for another one of your pieces, like a rook or bishop.
This is called a "discovered check," and it can be a huge problem for your opponent. By getting your pawn out of the way, you might suddenly spring a trap, putting their king in check with a major piece. In some very rare and cool situations, this discovered check could even lead to an instant checkmate. So, always keep an eye on what an en passant capture might open up!
Can You Capture Any Piece Other Than a Pawn En Passant?
That’s a great question, but the answer is a definite no. The en passant rule is only for pawns capturing other pawns.
You can't use this move to grab a knight, bishop, rook, queen, or king. The rule only works under the very specific conditions we've already talked about:
- Your Piece: Must be a pawn on its fifth row (or fourth row, if you're playing as Black).
- Opponent's Piece: Must be a pawn that has just moved two squares from its starting spot.
- The Target: The enemy pawn has to land on a square right next to your pawn.
Knowing these details is what separates a beginner from a more experienced player. Keep practicing, and before you know it, spotting and using en passant will feel totally normal.
