Possibly confirmation bias, but I often find a game I've won involved the loss (intentional or otherwise) of a pawn, which has opened up a file for rook attack, particularly on b/g files. Is there any catch-all term for this sort of gambit other than this title? I wonder if anyone has statistically analysed this type of scenario.
It is called a clearance sacrifice:
In a clearance sacrifice, the sacrificing player aims to vacate the square the sacrificed piece stood on, either to open up lines for his own pieces, or to put another, more useful piece on the same square.
