No, it is not refuted. It is a sound gambit, specially at your level. If you like the positions then go ahead, play it.
I think it is even played in correspondence games so that should give you a clue regarding if it is sound or not.
However you should be ok with the positions after Black declines the pawn.
For example after Nf6 you have to enter an Alapin and not a Morra anymore.
In chess there is no easy road, everything requires hard work.
If you want an answer to all variations of the Sicilian play the Closed Sicilian or the Grand Prix, there is not so much theory as in other variations, altough hard work is still required. This lines will save you time for more important things to improve like endgames/tactics and annotated games.
If possible try to get your hands on the "Starting out" series of the Closed and Grand Prix, I like the format, they quickly explain the theory and pass on to sample games which will benefit every player, even if he doesnt play those lines as the authors do a good job on explaining the position and games in general.
I hope that helped you.
Have a wonderful day m8!
Looking at this against the Sicilian. They say it strikes fear into Sicilian players. (if they go 1...e5, I'll just go Urusov, if they 1...c5, then the Morra Gambit is supposed to really take them out of their game and lots of traps they can fall into. Supposed to be very tactical?
Main line is Morra Gambit Accepted... (below is an example. To me, Black looks pretty good here and is a pawn up; though jammed up, hasn't castled yet and white has more space, already castled, can own that d file soon)
Is this opening for White sound and quite good for against under 1700-1800 players?
