In chess, a passed pawn is a pawn with no opposing pawns to prevent it from advancing to the eighth ; i.e. there are no opposing pawns in front of it on either the same or adjacent files.

Touch-move Rule
The touch-move rule in chess specifies that a player, having the move, who deliberately touches a piece on the board must move or capture that piece if it is legal to do so. If it is the player's piece that was touched, it must be moved if the piece has a legal move. If the opponent's piece was touched, it must be captured if it can be captured with a legal move. If the touched piece cannot be legally moved or captured, there is no penalty. This is a rule of chess that is enforced in all formal competitions. A player claiming a touch-move violation must do so before themselves touching a piece. A player who wants to adjust a piece on its square without being required to move it can announce the French ''j'adoube'' ("I adjust") before touching the piece. While ''j'adoube'' is internationally understood, a local language equivalent such as "adjusting" is usually acceptable. A player may not touch the pieces on the board during the opponent's turn. There is a separate rule tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sealed Move
Some board games, such as chess and Go, use an adjournment mechanism to suspend the game in progress, or at least did so before the advent of computer programs that play that game better than any human. The rationale is that games often extend in duration beyond what is reasonable for a single session of play. Adjourning the game would allow it to be continued at another time, typically the following day. There may be a : the next move that would be made is sealed in an envelope, to be played out when the game resumes (normally played by the director or arbiter). This practice ensures that neither player knows what the board position will be when it is their next turn to move. Chess Before chess programs achieved strength, and then became better than the best humans, adjournment was commonly offered in tournaments. When an adjournment is made, the player whose move it is secretly writes their next move on their scoresheet but does not make the move on the chessboard. Both opp ...
