Sicilian defense mengarini variation

I invite other mengarini players to join this thread and provide your valuable suggestions, I know there will not be many but, those who are may be very attacking players who are ready to play risky chess.

1. e4 c5 2. a3 Nc6 looks cool but 3. b4!? is a definitely dubious gambit.

 N.B. Sicilian: Mengarini Variation can be also obtained from Anderssen's Opening: 1. a3 c5 2. e4.

I found this gambit from a video here in the spicy gambit series, Since I am not a premium member I could not check my perfomance in this line with chess.com opening explorer, if you could do that , please let me know my perfomance in this gambit. I think I won majority of them but against lower rated players, this makes the Sicilian player discomfort , and the psychological move works ,but as the rating goes higher the efficiency of this gambit and this psychology tends to be lower.

Jiju__k: No problem, bro, your performance is 3:1 (black always played 3...cxb4). U won 2 games with 4. Nf3, 1 game with 4. axb4 and U lost 1 game with 4. Bc4. U can challenge me if U wish.

3.b4 is just part of a3. If u don't play b4, a3 doesnt make any sense.

It is just Wing gambit deferred (or delayed wing gambit, nobody calls it Megarini variation), and as jiju pointed out, u can watch video by S.Williams on chess.com who explains why 2.a3 instead of 2.b4 first.

I will not give more information as no need to reinvent the wheel, just watch :

IM Poucin: Following your logic, Anderssen's opening 1. a3 makes no sense since it's almost never followed by 2. b4. More importantly, Sicilian: Najdorf 5...a6 makes no sense since it's rarely followed by immediate 6...b5. Come on, even technically speaking, a3 and a6 are irreversible moves definitely changing the pawn structure.

It is always difficulty handling sicilian from white, and as a gambit player ( I consider myself so) I played smithmorra gambit and majority of them were lost to the players of my rating range, and then I went on to play open sicilain , it does provide good games, but there is not much fire works, and when I saw this Spicy gambit video I went for it. I memorised the rook sac line mentioned in the video, but I never played it. I don't know I will get a chance to play that any time soon. Each time I play this opening ,the lines appear are much more different from the video. 

If you know any material about this opening please let me know.

 Sorry but...

- In Najdorf, Black almost always plays b5 if he can.

- Anderssen's 1.a3 's big idea is not to play b4 : it is just to play with black a3 added which can be useful in many transpositional variations.

Well, i never read this book but it has a very good pedigree :

IM poucin. Sir thanku for the information, but I am sorry to say that for that price I can buy an used car here in India. 

Wow RoFL Come on, buddy, a chess book is more important than a used car! Fortunately, I don't have a driver's licence and can avoid such dilemmas. 

Intermediatedinoz: How these openings are related? ... Hmm,  well, there is an axial pseudo-symmetry wrt the middle vertical line.

If u search on google, u can have some pages of this book for free...

The same about Soloviov's "The Modern Anti-Sicilian: 1.e4 c5 2. a3".

Soloviov helped Bezgodov in the "classical" challenging sicilian a3, he just updates the work of his mentor, and adds many variations he worked because he played the variation during many years.

7 bd2 , led to exchanges q side ,

wondering if bb2 has merit esp as black went g6 , bg7 ,

1. e4 c5 2. a3 Nc6>>

I would play 2. ...e6 or maybe g6 if i was feeling like fun.

I like it. It leads to interesting positions.

It's not very good though.

1. e4 c5 2. a3 Nc6 3. b4 b6>>

I wonder what should be played instead of ...b6? Is ...e6 or ...e5 the best move? Not ...b6 though, surely.

Great! Here's the main line with 3...Nf6! :

and black has the advantage (ChessOK: -0.26).
