White's pawns on the b-file and on the e-file are doubled

In chess, doubled pawns are two pawns of the same color residing on the same file. Pawns can become doubled only when one pawn captures onto a file on which another friendly pawn resides. In the diagram, the pawns on the b-file and e-file are doubled. The pawns on the e-file are doubled and isolated.

In most cases, doubled pawns are considered a weakness due to their inability to defend each other. This inability, in turn, makes it more difficult to achieve a breakthrough which could create a passed pawn (often a deciding factor in endgames). In the case of isolated doubled pawns, these problems are only further aggravated. Several chess strategies and openings are based on burdening the opponent with doubled pawns, a strategic weakness.

There are, however, cases where accepting doubled pawns can be advantageous because doing so may open up a file for a rook, or because the doubled pawns perform a useful function, such as defending important squares. Also, if the opponent is unable to effectively attack the pawns, their inherent weakness may be of little or no consequence. There are also a number of openings that accept doubled pawns in exchange for some prevailing advantage, such as the Two Knights Variation of Alekhine's Defence.

Final position, Black to move, draw

It is possible to have tripled pawns (or more). The diagram shows a position from the Lubomir Kavalek versus Bobby Fischer game in the 1967 Sousse interzonal. The pawns remained tripled at the end of the game on move 28 (a draw).

Quadrupled pawns occurred in the game Alexander Alekhine versus Vladimir Nenarokov in 1907, in John van der Wiel versus Vlastimil Hort in 1981, and in other games. The longest lasting case of quadrupled pawns was in the game Kovacs versus Barth in 1994, lasting 23 moves.[1] The final position was drawn, demonstrating the weakness of the extra pawns (see diagram).

Different types of doubled pawns (from Berliner)

There are different types of doubled pawns (see diagram). A doubled pawn is weak because of four considerations:

  1. lack of mobility
  2. inability to act as a normal pawn
  3. likelihood that it cannot be exchanged for an opposing normal pawn
  4. vulnerability to attack, as the front pawn cannot be defended from behind by a rook

The doubled pawns on the b-file are in the best situation, the f-file pawns are next. The h-file pawns are in the worst situation because two pawns are held back by one opposing pawn, so the second pawn has little value (Berliner 1999:18–20). See Chess piece relative value for more discussion.
