Dominate with the Center Game and Danish Gambit
The Center Game
The Center Game begins after 1. e4 e5 2. d4
It is called the Center Game because you put two pawns in the center(duh). Your opponent has 2 responses: accepting or declining. If they decline the game usually transposes into another opening. For example if they decline with 2. ... Nc6, this is now the Nimzowitsch Defense: Kennedy Variation.
The response we play is the natural d5, kicking away their knight. If Nd4 play c3, winning the knight. If Nb4, f4(according to computers) and after they take Nf3. If Na5, do the same thing, except instead of Nf3 you play Bxf4. Nb8 is too passive so the only real move is Nce7.
After Nce7 play Nf3 attacking their e5 pawn. The only plausible way to defend is Ng6. That knight is awkward and has moved to many times in the opening. Play h4, preparing to kick it away and take on e5. The best response is h5 and now play Bg5.
Their only other way to decline is with d6. This has transposed to the Pirc Defense: Maróczy Variation. Best move is Nf3 and another transposition has happened. This is now called the Philidor Defense. The more simpler, but less advantageous approach is to trade pawns, then queens and attack f7.
f3 is the only way not to decline the center game. If f3, trade and if they recapture Qh5+! You will win.
The only real option is to accept it and take on d4 at the beginning.
The Mainline is to recapture with your queen(hence this variation being called the Normal Variation). When they play Nc6, the best and basically only good move, we will bring the queen to e3. Our next moves are automatic, we will play Bd2, then Nc3.
If they push d5, in a position like the case above, trade pawns and move the queen to g3 attacking g7. If they trade knights after doing something like Bf6 to defend g7, take back with the bishop. This helps us as add pressure to g7.
If they don't trade, whatever, keep developing and play a solid game. Also, the reason we don't push e5 is because of Ng4 attacking the queen. If our queen is ever attacked move it to g3. They can't castle to defend g7 because of Bh6, which can be dangerous for black.
