Queens "Gambit"

The Queens gambit is a very old chess opening that everyone knows (besides the very new). The idea basic idea behind it is to "gambit" a pawn in the opening as such 1. d4 d5 2. c4 dxc4, going for the f1 bishop to capture back and with better development and a classical pawn center you will have a superior game. My interest lies in the fact that people call it a gambit because you are giving up the c4 pawn. But white will be able to capture the pawn back and if black tries to stop the recapture of his pawn white will have an even greater advantage, meaning it is not really a gambit. This is also supported by the fact that most players who play queens gambit openings are more calm than players who play e4 lines (although this is not always true).

One of the few ways black can save his pawn:

It was probably named that by analogy to the King's Gambit.

qc7 and bb7 and its trapped maybe

4.Qc5

7...Bb7 8. Rxa7. Regardless of this your position is incorrect as white still has the a-pawn shouldn't be there. The queen can't be trapped.

It's probably named like this since in the early days, black tried to keep his extra pawn, and it usually cost him dearly, Giving the QG a bad reputation.
