Need name

in openings like smith morra gambit white gives two pawns for quick development here black is a pawn down and in exchange  has a lot of space queenside, avoids the Bb5+ due to the a6 pawn and can play e6 and free the dark square bishop as well...ok iknow that with perfect play black is totally busted but in a blitz game of lower rated players it may have some success

What was the most important word in your last post?  "White."  The first player has some leeway with offering stuff as he is not already playing catch-up.  Nevermind whether the gambit would be sound with an extra tempo.

No problem, just pointing it out 

this defence can be a serious problem for white only if it  transposes to the Benko or else i know that black cannot win at medium or high level chess  with it...

Right.  At low level, by process of elimination, people generally do not (or should not) study openings so the point would be moot.  In any case, if the position is basically unsound better moves will come to the side that is ahead than if it was not.  Good positions lose less often than bad ones.

this is a transposition to the benko....

Majikthise

I thought about this as well...1. ...Nf6 2. ...a6 3. ...b5 4. ...Bb7

Yeap...pretty much

Dmitry Gurevich had some sucess with this line...

Thanks i will try to find some of his games with it:)

Seems like Benko/Volga lines to me

I would call it "Queen pawn opening with early ...a6".

As i think about it again although after b5 cxb5 axb5 and the a file is open...it seems to me that this may not be the best choice...

<GreenLeaf14> I'm glad that you liked my suggestion :-)

No prob Mr. solskytz..buat i was also thinking sth like ''People's defence'' or ''Alpha defence"(from a6) i don't know...any other suggestions?

Lol I thought I invented that =)

Call it the Fonzi   -   aaaaa6

Accelerated Benko...hmmm...nice name,though i do not think many oppenents will opt to play the Benko against it...
