The Queen's Gambit from the Closed Games openings may give white to squeak out a small initiative, but for black, it has the advantage of being very solid. Every world champion has played the black side of the Queen's Gambit which follows 2. c4.
1. d4 d5 2. c4
Try yourself the Queen's Gambit opening below. You have white pieces and need to move your Pawn to c4 to complete the
