7.Passed Pawns

In general, having a passed pawn is an asset, especially in endgames. An outside passed pawn can mean a victory, but keep in mind that it may not always be an advantage. If the pawn is blockaded well, usually by a minor piece (especially a knight), that pawn can become weak and vulnerable at some point, and can be potentially under attack by the opponent's pieces. Last thing to add here is that having a protected passed pawn is definitely an asset, when the passed pawn can't be captured and an enemy piece has to always stand guard near it so it doesn't promote.
