I don't understand all the remarks about this (from the OP) not being a queen sacrifice.
In chess, the queen is the most powerful piece, and giving it up for all kind of reasons is simply often called a queen sacrifice.
Just like the "exchange sacrifice" is called a sacrifice. Maybe because you trade a rook (5 points) versus either a knight or a bishop (3 to 3.5points). That is theoretically a material loss, but there can be compensation on the chessboard.
If you give you queen (10 points, in some systems 9 or 9.5) for example versus a rook (5 points) and two pawns (2 points) you can also call it a queen sacrifice.
