And, after Black has castled Q R, he has the better game.
THE DANISH AND CENTRE GAMBITS.
The opening moves in each case are 1. P to K 4, P to K 4; 2. P to Q 4, P takes P. If White continue 3. P to Q B 3, it is called the Danish Gambit, which is rarely played now. The Centre Gambit is a modification of the Scotch, and similar to it in many of the continuations. 3. Q takes P constitutes this Gambit. (Strictly speaking, it is not a Gambit, the pawn not being sacrificed.) Latterly the Centre Gambit has been somewhat neglected.
