This opening is very rare in tournaments, and it's my opening against Sicilian. I'm still studying all possible moves of this opening against Sicilian. As far as I know this opening is called "Sicilian: Halasz Gambit" but some confusing in this name because Halasz gambit is well known in 1.e4 e5 2.d4 exd4 3.f4, for you not to be confuse you can called it as Bendcat Gambit. Is this possible?

 

 

Is it possible to call it bendcat gambit?  

thoughts... 

I'd heard there was an opening called The Monkey's Bum, but I didn't know what it was. Thanks for the link!

Fisrt time I am seeing that...

Not ... normal.

hmm... can I called it bendcat gambit?

What can White play after 3...Nc6 4 Nf3 d5 5 exd5 Qxd5?

Black's uncaptured d pawn has suddenly become rather useful to him, and bothersome to White.

Yes, it is possible move 5. exd5 but it will lead to black queen to position in the center. I think it is better after 4...d5 is 5. e5 in my opnion.

I'm not sure I understand the White strategy in that case. Can't Black put a queen on b6 and a knight on f5, and keep the pawn permanently with a better position? Just look at Black's pawns.

In other words, why does White want to offer this gambit, and what is the benefit?

5. Bb5 (i'm not a chess player so i wouldn't know the best move after this...but)

5...if exd5 then 6.Nxe5 and positional advantage with knight in the centre. 

5...if Bd7 then exd4  and keep up tempo while regaining the pawn.

A big gambit and i'm sure black could have a better move i'm just not seeing it? 

5 Bb5 (or 4 Bb5) loses a piece to Qa5+.  Black's free central pawn showing its value.

Hmm..ok so good point,

soo we have 4...d5

5. Nxd4(?) I'm not really sure what follows but it does seem to give white leg up in tempo. 

 

 

The thing is, Black is just as ready for an opening of the center as White is. Still waiting for someone to attempt to justify this gambit, and the reasoning or strategy behind it.

Bendcat seems to be winning games with it. But that could just be because he is a strong player, not because the gambit is good.

The idea of this gambit is to use the uncaptured black pawn to protect the white king. The spot d4 is in the line of strong diagonal attack of black, combining the queen at b6 and bishop at c5. To properly use the uncaptured pawn is to put your bishop at d3. I always see some games like this, they are using the opponent piece to protect their king.

 

Now if white castle in king side, white will not be trouble with the attack in diagonal a7 to g1, and result for white to have a strong king side because of developed rook at F-file. In Sicilian the black always castle in king side and from that point you have a chance of attacking the black king.

 

This is just my simple game plan, hope you can came up with better varations.

 

Interesting ideas.  I can agree with these points, but would still like to see more specific variations. I may try it out myself for research.

This is called the sicilian Andreaschek gambit. It leads to an unclear situation. Traditionally, after 3. f4, comes ...g6, then 4. Qxd4, Nf6, and then finally, 5. Nc3.

It looks like a clear advantage to white, due to the central control, and mobility. Probably a good counterattack opening for black.

As a Sicilian player here's what I'm looking at.

 

 

I'm sure I'm missing some good variations. Don't forget the move list!

this is a variation that has appered and dissapered quite frequently in my play. and also this is the third time this opening (or openings of the soort) have appered on this site. the theng that most people dont understand is that this is a verry bendable opening. just because you are immediatly breaking the sicillian dosn mean that you cant play a sicillian game. after f4, the game can continue on as a grand prix variation of the sicillian, or can

go into lines of the halasz gambit that people dont know very well. 

also note that there is nothing "unclear" about this opening. whites attacking ideas are pretty clear cut.also for referance this isent really supposed 

to be an open game 

the elo lines of the scilian defence:halasz gambit

  variation 1 and 2

I meant unclear who has the advantage.

foreverzero, in your first diagram, why 5. ... e6 instead of 5. ... Bg4. Black seems to get a good game after Bg4.

 

In the second diagram, do you really mean for white to hang his bishop with 8. Be3? The pawn on d4 can take that bishop, or did I miss something?

whops, thats supposed to be Bd2 not Be3 ^_^! sorry about that

and also you HAVE to move the e pawn to place a bishop on g4. either way  

e5 or e6 has to be played. i prefer e5 because it takes more claim on the center.
