A pawn without neighbors
An isolated pawn has no pawns of its own on the files next to it. No pawn can protect it, so the pieces have to. On the d-file it is called an isolated queen's pawn, and then it stands in the middle of the board, where everything happens. We will follow a game where both sides' plans show clearly: Botvinnik vs. Vidmar, Nottingham 1936.
The position is balanced. White has more space and open lines: the bishops and the queen can aim at the kingside, and the rooks can use the c- and e-files. The pawn also takes the squares e5 and c5 away from Black. Black's pawns have no weaknesses, and Black has something White doesn't: the square d5, which no white pawn can ever attack.
Where does it come from?
The isolated queen's pawn arises from many openings, for both colors:
- The Queen's Gambit Accepted: Black captures on c4 and later on d4, and White often gets the pawn on d4.
- The Panov Attack in the Caro-Kann: White trades in the center and plays c4, and after the trades the pawn on d4 is left alone.
- The Tarrasch Defense in the Queen's Gambit and the Tarrasch Variation of the French: here it is Black who gets the pawn, on d5.
- The Italian Game with c3 and d4 can give it too, as in Steinitz vs. von Bardeleben, 1895.
The plan for the side with the pawn
The pawn is at its strongest with all the pieces on the board. The side that has it therefore wants to play actively and quickly, before the trades begin.
- Pieces forward. A knight on e5, where the pawn protects it. The bishop aimed at the kingside, preferably on b3 or c2. The queen and the rooks behind.
- An attack on the king. Often with the f-pawn, as in Botvinnik's game, or with a rook lifted up via the third rank.
- The d4–d5 break. When the pieces are ready, the pawn can advance and open the lines. It may be lost, but it has done its job.
- No needless trades. Almost every trade makes the pawn weaker.
Here both sides have done what they should. White's knight stands on e5, and Black's knight has settled on d5, in front of the pawn. A few moves later Black moved the knight to b4 and put the bishop on d5 instead. White captured it, and then Black had a choice to make.
The plan for the side against the pawn
- Blockade. Put a piece, preferably a knight, on the square in front of the pawn. No pawn can chase it away there, and the pawn gets no further.
- Trade. Especially the pieces that can attack your king. With fewer pieces, the isolated pawn has less to give.
- Press against the pawn. The rooks on the d-file, a knight and the queen against d4. The more pieces White needs to protect it, the fewer are left for the attack.
- Aim for the endgame. There the pawn is often just weak.
The attack
Vidmar chose the wrong knight. All of White's attacking pieces were left on the board, and now came the attack that the pieces behind the isolated pawn had been preparing.

The d4–d5 break
The isolated pawn has a weapon of its own: moving forward. When it goes to d5, lines open, and the pieces that stood behind it come into play at once. Steinitz played it against von Bardeleben in 1895. Black's king was still in the middle, and the knight on e7 was pinned by White's queen and rook on the e-file.
Common mistakes
- Passive play with the pawn. If you only protect the pawn and trade pieces, you end up in an endgame where the pawn is a target.
- Taking the pawn too early. Grabbing the pawn before it is blockaded and the pieces are traded often opens the lines for the opponent.
- Leaving the king. Against the isolated pawn you need defenders on the kingside. If every piece goes to d5, the attack comes on the other side.
Remember
- With the pawn: active pieces, an attack, and the d4–d5 break when it opens lines.
- Against the pawn: blockade the square in front, trade, and aim for the endgame.
- The trades decide. The fewer the pieces, the weaker the pawn.
The pawn has a close relative: when two pawns stand side by side without neighbors, they are called hanging pawns. Read about them and other structures on the page about pawn structures.
Frequently asked questions
Is an isolated queen's pawn good or bad?
Both. A white pawn on d4 gives the pieces room, open lines and the squares e5 and c5, and it can support an attack. But it has to be protected by pieces, and the square in front of it, d5, is an excellent square for the opponent's knight. The more pieces are traded, the weaker it gets.
Which openings give an isolated queen's pawn?
Among others the Queen's Gambit Accepted and the Panov Attack in the Caro-Kann, where White often gets the pawn on d4, and the Tarrasch Defense in the Queen's Gambit and the Tarrasch Variation of the French, where Black often gets it on d5.
How do you play against an isolated queen's pawn?
Blockade the square in front of it, preferably with a knight, and trade pieces, especially the ones that can attack your king. In the endgame the pawn often becomes an easy target.
