Candidate passed pawn

A candidate passed pawn is not yet passed. No enemy pawn stands ahead on its own vertical file, but one or more enemy pawns on neighboring files can still capture it if it advances. The pawn layout, however, offers a realistic sequence of advances or exchanges after which it could become a passed pawn, with no enemy pawn between it and the last rank on its own file or either neighboring file. On reaching that rank, it could become another piece.

Candidates often arise where one side has a pawn majority, meaning more pawns than the opponent in one area of the board. That numerical edge may allow one pawn to be exchanged while another survives. Not every pawn in a majority is a candidate: there must be a concrete route to creating the passer.

How to identify one

• Work out the possible pawn advances and exchanges in that part of the board.
• Look for a push that makes the opponent capture and lets another pawn recapture, or leaves the opponent without an adequate pawn reply.
• Then check that pieces, checks, and other immediate threats do not prevent the transformation.

The word candidate describes potential, not a guaranteed status. Timing matters: pushing too early can let the opponent blockade the pawn, win it, or fix the structure in a favorable way.
