Whereas this definition is obvious for a human, in a form presented above it would require no less than a separate [[Recursion|recursive]] search routine. For that reason, computers have to use approximations of that rule. One possibility is to define a pawn as a candidate, if no square on its path is controlled by more enemy pawns than own pawns. However, this simple heuristics rules out an early recognition of a candidate passed pawns. For example with white pawns on a4 and b5 and black pawn on a7, the b5 pawn would be viewed as a candidate passer only after a4-a5. || || White and Black candidates (b5, g5) ||~ ||^ || [[toc]] =See also= * [[Candidates (Bitboards)]]. * [[Faker]] * [[Hidden Passed Pawn]] * [[Passed Pawn]] * [[Pawn Majority]] * [[Unstoppable Passer]] =Forum Posts= * [[http://www.stmintz.com/ccc/index.php?id=476471|How to define a candidate passer]] by [[Jan Willem de Kort]], [[CCC]], January 03, 2006 * [[http://www.stmintz.com/ccc/index.php?id=489960|Outside passer and candidate passer: definition wanted! :-)]] by [[Alessandro Scotti]], [[CCC]], February 27, 2006 * [[http://www.talkchess.com/forum/viewtopic.php?t=37748|Improving evaluation of passed pawns]] by [[Ben-Hur Carlos Vieira Langoni Junior]], [[CCC]], January 22, 2011 ยป [[Passed Pawn]] =External Links= * [[https://www.chess.com/forum/view/chess-equipment/pawn-power-in-chess-by-hans-kmoch-glossary-of-terms|Pawn Power in Chess by Hans Kmoch - Glossary of Terms - Chess Forums]] - [[https://en.wikipedia.org/wiki/Chess.com|Chess.com]] <ref>[[Hans Kmoch]] (**1959, 1990**). //Pawn Power in Chess//.
