No.
Should I play smith-morra gambit?

Sveshnikov played the Alapin at top level. Smyslov and Spassky played the closed Sicilian against top grandmasters. Hebden, Polgar etc. played the Grand Prix Attack against strong grandmasters. The preferred version is with Bb5, not Bc4.
Caruana played the Rossolimo in the World Championship Match.

the openings like the alapin or grand prix are rarely played at top level and are only played as a sideline to deviate out of mainline theory. No GM actually plays these as a main weapon (other than the rossolimo, which is very playable at all levels)

The Morra gambit will still get results up to 1800 but beyond this odds are then stacked against you, its worth pointing out though black has several ways to decline this gambit one is the early ... Nf6! The other being returning the pawn and avoiding the open c=file 1.e4,c5 2.d4,cxd4 3.c3, and now ...d3!? After 4.Bxd3 blacks plan would be to play a type of pirc setup with ...d6 followed by ...Nf6 and ...g6, white will still hold an edge but without the dangerous open c file!!?
i'm 2200 and i get good results using the morra. most people don't know how to play the opening especially at sub 2000. learn the ideas of the opening and you will have great attacking chances

As a reply to sicillian?
i recommend delaying the alapin and only playing it if they play 2.d6 in order to avoid the paulsen kan setup (which is very annoying to face)
It was normally thought that the Alapin is weakest of all when it's delayed a move and played after 2. ...d6, since then, after 3. c3, the correct move is obviously 3. ...Nf6 and ...d6 has been played to make e4-e5 more difficult. There was a GM in the 1980s who was determined to find an advantage for white and he explored lots of lines and claimed he found one with a tiny edge for white but it was normally thought that 1. e5 ...c5 2. Nf3 ...d6 3. c3 ...Nf6 is slightly better for black and that 3. c3 is therefore wrong. It might have been Larry Smith.
Against the setups with e6, white should be happy because it's just a main line Alapin, although there are at least five distinctly different ways black can play it, which might be the cause of white's sdginess about playing the Alapin, but there's no need to worry because the Alapin is completely solid for white. It isn't as if white's a pawn down and has to attack at all cost. The Alapin is definitely the thing to play as white against a much stronger opponent, because the likelihood of getting a draw is quite high.
i mean this

Oh ok. But doesn't that allow 4. ...Nf6 in the same way? Maybe white can play 5. Bb5+ but after Bd7 6. Qe2 ...Bxb5 7. Qxb5+ ...Qd7, things don't look good for white so maybe white has to play 5. e5. I'm going to look at that with the analysis tool.
4.Nf6 5.Qxd4 Nc6 6.Qe3 is equal

Remember guys I am only 1300 my opponents are not likely to know a lot of these lines you're talking about
....... In fact, white has a positional line against it, which is rather good and very difficult for black.
What is the positional line?
My results against it have been ok but only because I was usually making the next to last mistake in positions I didnt like for either side. I'd love to have a line against it that led to positions that made sense to me.
Thanks-- Bill
