Opening Trap In The Queen's Gambit!

You know the chess traps? Well, this is an old trap that has taken many Black players out of the game! It is one where Black will lose a rook in the QGA. That's why I prefer the Slav Defense, especially not to block my c8-bishop in.

Anyways, I hope you like this trap!

I do not know the name of the trap but it is certainly a nice one.
