'''Hanging pawns''' are an [[Open Pawns (Bitboards)|open]], [[Isolated Pawns (Bitboards)#IsolanisSetWise|half-isolated]] [[Duo Trio Quart (Bitboards)|duo]]. It means that they are standing next to each other on the adjacent [[Half-open fileFile|half-open files]], usually on the fourth rank, mutually protecting their [[Stop Square|stop squares]]. They share a number of characteristics of weak pawns - they are not directly protected by other pawns and may become targets of attack - but unlike them they have dynamic potential of executing a pawn breakthrough and thus creating a [[Passed Pawn|passed pawn]] (admittedly being an [[Isolated Pawn|isolated pawn]] at the same time). The side with hanging pawns also tends to enjoy a [[Space|space]] advantage.
