Candidate Passed Pawn
Home * Evaluation * Pawn Structure * Candidate Passed Pawn
| Candidate passed pawn, a pawn on a half-open file, which, if the board had only pawns on it, would eventually become a passed pawn by moving forward. Whereas this definition is obvious for a human, in a form presented above it would require no less than a separate 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. |
