What Does En Prise Mean?
A piece is en prise — French for 'in take', pronounced roughly 'on preez' — when the opponent can capture it and come out ahead in material. That is broader than the familiar hanging piece: a piece can be en prise while defended, if it is attacked more times than it is defended, or if its only defender is too valuable to recapture. When a commentator says 'the bishop is en prise', they mean one thing: it can simply be taken, at a profit, right now. Learning to spot en prise pieces — the opponent's before you capture, your own before you move — removes more blunders from your chess than any opening file ever will.
A Brief History
En prise comes straight from French: literally 'in take' — a piece standing within reach of capture. Like en passant and j'adoube, it belongs to a small family of French expressions that entered chess writing untranslated and stayed that way in every language: you will hear 'the knight is en prise' from commentators worldwide, pronounced roughly 'on preez'. The term has survived because no English word does its job. 'Attacked' is too weak — an attacked piece may be perfectly safe behind enough defenders. 'Hanging' is too narrow — club players use it mostly for the completely undefended case. En prise covers every situation where a capture turns a profit: undefended, outnumbered, or defended only by pieces too valuable to do the recapturing. That is precisely the situation a chess player needs one crisp word for.
The Three Flavours of En Prise
Flavour 1 — Attacked and undefended: the hanging piece
The simplest case: a piece is attacked at least once and defended zero times. Any capture wins it outright — a bishop on g5 attacked by a knight on f3, with no defender in sight, is just free. This is the case players informally call 'hanging', and it decides an enormous share of club games on its own.
Flavour 2 — Defended, but outnumbered
When attackers outnumber defenders, the piece falls anyway: attacked twice and defended once means capture, recapture, capture — and the last word is yours. Start the sequence with your cheapest attacker so every recapture trades up. A knight attacked by a rook and a knight, but guarded by only one piece, is en prise even though it looks 'protected'.
Flavour 3 — Defended, but only by the wrong piece
A defender only counts if it can afford to recapture. A bishop attacked by a pawn and 'defended' by the queen is still en prise: pawn takes bishop, queen takes pawn back, and the attacker has won a bishop for a pawn. Whenever the only defender is worth more than the attacking piece, the defence is an illusion.
How to Stop Leaving Pieces En Prise — Step by Step
Attacked and Undefended: The Hanging Piece
Black's g5-bishop is attacked once — by the f3-knight — and defended zero times. That is en prise at its simplest: Nxg5 wins a whole bishop for nothing.
Outnumbered: Two Attackers, One Defender
The d5-knight is attacked twice (the d1-rook and the c3-knight) but defended only once, by the f6-knight. White captures with the cheaper piece first: after Nxd5 Nxd5 Rxd5, White has won a knight.
Defended — but Only by the Queen
Black's d4-bishop is attacked by the c3-pawn and 'defended' by the d8-queen. The defence is an illusion: a queen cannot profitably recapture against a pawn, so cxd4 wins a bishop for at most a pawn. When the only defender is worth more than the attacker, the piece is effectively en prise.
En Prise on Purpose: The Poisoned Piece
White's d6-bishop is attacked by the d8-rook and defended by nothing — genuinely en prise. Yet Rxd6 loses on the spot: that rook was guarding e8, and Re8 would then be checkmate on the back rank. En prise describes a fact on the board, not an order to capture.
Common Misconceptions
En prise just means 'attacked'
An attacked piece can be completely safe. A knight attacked once by a rook and defended once by a pawn is not en prise: Rxc6 bxc6 gives up a rook for a knight. En prise means the capture comes out ahead — the piece is undefended, outnumbered, or guarded only by something too valuable to recapture.
If it's defended, it's safe
Defence is arithmetic, not a status. Two attackers against one defender means the piece falls: capture, recapture, capture. And a lone queen 'defending' a bishop against a pawn attack defends nothing at all — pawn takes bishop, queen retakes a mere pawn, and the material is gone for good.
A piece left en prise is always a blunder — so always take it
En prise describes a fact on the board, not a verdict on the move. Strong players leave material en prise deliberately: poisoned pieces whose capture walks into a back-rank mate or a fork, and desperado pieces that sell themselves for the highest price because they are lost anyway. Count first — then ask why it is free.
Can You Count It?
Count attackers and defenders, then decide
Two against one
It is White to move. Count the attackers and defenders of the black knight on e5. Is it en prise?
Defended by the queen
It is White to move. Black's d6-bishop is attacked by the c5-pawn and defended by the d8-queen. Is the bishop safe?
Attacked — but not en prise
It is White to move. The c1-rook attacks the black knight on c6, which is defended once by the b7-pawn. Is the knight en prise?
Can You Spot It?
Three positions: take the free piece — or leave the poisoned one
One black piece is en prise — genuinely free. Find it and take it.
Count the attackers and defenders of the knight on d5, then win a piece with the right capture.
White's bishop on d6 is attacked and completely undefended. Should you take it — and if not, what instead?
En Prise in Your Openings
Where club players hang material most
Italian Game
The Italian (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5) starts the en prise lesson on move two: Nf3 attacks the e5-pawn and Nc6 defends it — one attacker, one defender. Every time that c6-knight moves or is exchanged, e5 must be recounted, and the bishops on c4 and c5 sit on open diagonals where one tempo-gaining move can leave them short of defenders. Recount the centre after every trade.
View opening pageLondon System
In the London (1.d4 followed by 2.Bf4), the moment the dark-squared bishop leaves c1, the b2-pawn loses its only defender. Black's standard test is ...Qb6, putting b2 en prise and daring White to ignore it. White has clean answers — Qb3 or Qc1 — but only if the threat is seen in time; countless London games are decided by ...Qxb2 landing unanswered.
View opening pageScandinavian Defense
The Scandinavian (1.e4 d5 2.exd5 Qxd5 3.Nc3) is an en prise drill from move three: Nc3 attacks the queen on d5 and she must move at once. Playing it as Black — or facing it as White — trains the core habit early: after every developing move, ask which enemy piece it attacks, and never leave your queen standing where a cheaper piece can hit her.

Pitfalls to avoid
Grabbing first, asking why later
The reflex capture is the poisoned piece's best friend. A piece that looks free is sometimes bait — the classic pattern is a rook lured off the back rank to win a bishop, only to be mated by a check behind it. Make the one-second check standard before every capture: what does the opponent's reply gain — a check, a fork, a mate threat? If the piece is free for no reason, it is simply free; take it and be happy.
Moving the defender away
Pieces rarely hang where they stand — they become en prise because their defender just left. You develop the knight that was covering a central pawn, or push the pawn that was guarding a bishop, and a piece that was safe for ten moves is suddenly free. When any of your pieces moves, recount every friendly piece it was defending. This is the same logic as removing-the-defender and overloading tactics — applied preventively to your own camp.
Counting pieces, but not values
'Attacked twice, defended once — I can take!' is only half the calculation. Capture with the wrong piece and the count betrays you: a rook capturing first on a square a knight defends trades five points for three. Start every exchange with your cheapest attacker, and never call a piece 'defended' when its only guard is a queen facing a pawn or minor-piece attack — she cannot afford the recapture.
Tips for Club Players
Make the scan a ritual: after every opponent move, ask 'what does that attack?' — trace the moved piece's new lines before you start thinking about your own plan.
Before releasing your own move, look backwards: what was the piece you are moving defending? Pieces become en prise when their guard walks away.
Count literally — attackers versus defenders — on every piece that stands where it can be captured. More attackers than defenders means it falls.
Capture with your cheapest piece first: pawn before knight, knight before rook, rook before queen, so every recapture trades up instead of down.
Treat the queen as a non-defender: anything guarded only by her is effectively en prise to a pawn or minor-piece attack, because she cannot afford the recapture.
When a piece is free, spend three seconds on 'why?' — look for a check, a mate threat or a fork that follows your capture. No reason found? Take it.
Frequently Asked Questions
Everything you need to know about en prise
En prise is French for 'in take'. A piece is en prise when the opponent can capture it and come out ahead in material: it is undefended, or it has more attackers than defenders, or its only defender is too valuable to recapture — like a bishop guarded only by the queen against a pawn attack. Commentators use it as shorthand for 'that piece can simply be taken'.
Roughly 'on preez', keeping the soft French nasal on the first word. Like en passant, the term stays French in every language — there is no translated version to learn, which is exactly why it has survived in chess commentary worldwide.
'Hanging' is the informal word for the simplest case: attacked and completely undefended. En prise is the broader, classical term — it also covers pieces that are defended but outnumbered, and pieces whose only defender is too valuable to recapture. Every hanging piece is en prise, but not every en prise piece is hanging.
Almost always — free material wins club games — but count first and ask why it is free. Some pieces are left en prise deliberately: capturing a poisoned piece can walk into a back-rank mate, a fork or a queen trap, and a desperado piece is offered precisely because it was lost anyway. If you find no tactical reason the piece is free, take it.
