Also, it depends on if you like sharp openings or positional play. I prefer the sharp openings
D4 is better than E4 and C4 and its also whatever works best for you

1. No one plays the Smith-Morra Gambit, one of the above openings.
2. White is favorable in the second opening, a bad Alapin for Black,
3. No one really plays the Exchange Variation of the Rudy Lopez.
at the average 500 ELO level through 800 ELO level where most players are at these are really often played nobody knows that the pawn is not free in the Morphy defense what is the Rudy Lopez Smith morra gambit is played by 1600's I've watched games at that level and the alapin Is considered losing advantage. Gothamchess might tell you that for some people you should play the smith morra cuz it gives you a weapon against the Sicilian though not really its just another antisicilian.

Positional play allows a sharper attack later and the most attacking opening without gambiting a pawn is the Jobava London with over 300 attacking ideas contained within the Jobava London. The Jobava london is part of the Queens pawn opening.

The main ideas of the Jobava London are the Forking plan The pawn structure ruining trade the bishop trapping plan and the mating attack plan.
Also that Quillbot AI thing is because you guys wanted me to improve my grammar.
