Isolated Queen Pawn
The Isolated Queen Pawn is so common in chess positions that it is usually abbreviated as IQP. An isolated Queen Pawn is a pawn that is isolated and a Queen pawn ("dí pawn). For some reason, the "dí pawn is the most common pawn that becomes isolated in many chess openings. It is particularly common in Queen pawn openings, where other pawns may be swapped off, leaving the Queen pawn all alone.
IQP positions often revolve around the key positional issue of the isolated pawn. Will it be captured and lost? Or can it be saved and be strong in the center?
The player with an IQP will often have active piece play as compensation for the static weakness of the isolated pawn. Dynamic play often trumps the static weakness. Hence, the player with the IQP may seek to avoid piece exchanges, as the isolated pawn becomes weaker in the endgame. If an IQP can be advanced, then it can have a cramping effect on the enemy game. And sometimes the IQP is actually sacrificed to get more piece play.
The defender against an IQP will seek to blockade the isolated pawn. The goal is not to let the pawn advance. Then the IQP is a static weakness that can be attacked. As many pieces as possible are trained against the queen pawn in an attempt to simply win it. Alternatively, the player may simply use a strategy of exchanging pieces to head into an endgame, where the isolated pawn will be even weaker.
