You could write a book about IQP positions (maybe someone has).
Very generally speaking, the side with the IQP usually seeks active piece play, sometimes a kingside attack. The side playing against it wants to blockade it and trade pieces into an endgame where the isolated pawn is a liability, sometimes a fatal liability.

Winning Pawn Structures by GM Baburin is a book about the IQP in his entirety. Same goes for Beliavsky, Mikhalcsisin and Stetsko's book Isolani Strategy.


Trade minors if against the IQP, but keep Queen and at least one set of Rooks. Also hold a c- or e-pawn. the Rook goes in front of the pawn, blocking it, and the Queen goes behind it. If he tries to go behind to defend then push c/e-pawn then the IQP is pinned. The Queen makes the defender's King's participation risky
