Why play 5...a6?  Better is 5...e6!

Yes, this is a Grand Prix Attack. But both 6.Nf2 and 6.Bb5+ are more common.

I don't usually play  the Sicilian , but , by interversion of moves , I have got a GPA : the game went :
1 Nc3 c5 2 f4 d5 3 e4 e6 4 Nf3 dxe4 5 Nxe4 Nf6
6 Nxf6+ Qxf6 7 d4 Nc6 8 Be3 cxd4 9 Nxd4 Bc5
10 c3 e5 11 fxe5 Dxe5
It doesn't look very dangerous for Black 8)
Is that really a GPA? And why is it so popular? Roll Eyes

Josef Nun is a strong Czech corr GM, known for his love of classical sharp gambits such as the Danish. Has he published analysis of this 8.a3 idea anywhere?
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

New life for the Grand-Prix-Attack?

The first thing I heard about the Grand-Prix-Attack was that it is absolutely not dangerous for black after 1.e4 c5 2.Nc3 Nc6 3.f4 g6 (I find 3. ... e6!? more annoying to meet, but that's a matter of taste) 4.Nf3 Bg7 5.Bc4 e6 6.f5!? Nge7 7.fe6: fe6:! 8.d3 d5 9.Bb3 b5! and that he can fight for an advantage.
But there is a new idea by Josef Nun (not to be confused with John Nunn  Wink ), a czech player (probably IM), namely 8.a3!?
The point is to win a tempo in comparison to other variations  by moving the bishop to a2 in one move instead of two.
Lately I had a serious tournament game (my first GPA) which went 8.a3!? d5 9.Ba2 0-0 10. 0-0 b5 11.d3 (perhaps 11.Nb5:!? was possible, but I thought it was too risky) c4 12.Kh1 Bc3?! 13.bc3: de4: 14.Ng5! ed3: 15.Rf8:+ Qf8: 16.cd3: Ne5 17.dc4: bc4: 18.Qe2 Bd7 and here 19.Bd2 would have given me a significant advantage, the game was later drawn after 19.Be3?!, which may still be better for white. My opponent was rated about 2150.
Some opinions?

These lines combining Bc4 with a quick f4-f5 have been struggling for some years. The preference nowadays is a quick Bb5.

Yes, a4 is a loss of tempo. 1.e4 c5 2.Nc3 d6 3.f4 g6 4.Nf3 Nc6 5.Bc4 a6 6.d3 b5 7.Bb3 Bg7 8.o-o and the bishop is better on b3 than on c4:
A) 8...Nge7 9.f5! (9.Qe1 Nge7 10.f5 gxf5 11.Bg5 h6!)
A1) 9...exf5 10.Qe1 Ne7 11.exf5 Bxf5 12.Ng5
    is similar to Hodgson-Sjamkovitsj, Brighton 1982.
A2)9...gxf5 10.Ng5 h6 11Nxf7 Kxf7 12exf5 Nf6 13fxe6
   Bxe6 14Nd5 with an attack.
A3)9...h6 10.fxe6 Bxe6 11.Nd5 Mirzoeva-Baccarin
     Viaro, Menorca 1996.
B) 8...Nf6 9.Qe1 (9.f5 e6 10.fxe6 fxe6 is equal) o-o
    (Na5 and Qb6 have been tried without success)
    10.f5 (10.Qe1 is also good) b4 11Ne2 a5 12fxg6
    (12Qh4 gxf5 13Bh6) hxg6 Saulmon-Bohland,
    Cadillac 1999, 13Qh4 with good play.
So the early a6 is not a bust.

Chess is not a very democratic sport. Not only does FIDE do what they want, but also a move that is played by thousands of players is not necessarily a good one. As far as I can see experienced players including IMs and GMs refrain from playing a2-a4 in the GPA if not absolutely necessary. If beginners like a2-a4 it´s no sign of real quality.

<White almost never answers a7-a6 with a2-a4 >
Why are there so many games then in my database with the inclusion of a6 and a4?
But Stefan might be right indeed, stating that it is better not to play a4.

As a rule of thumb:

White almost never answers a7-a6 with a2-a4 in the GPA. One reason has already been given by the previous post with another being, that with the inclusion of a2-a4 White can´t retreat his Bishop to b3 anymore (after a future d7-d5) in view of Nc6-d4xb3 when White´s pawn structure is destroyed. If the Bishop goes to a2 instead, Nc6-Nd4xc2 might be a problem. So when in doubt refrain from playing a2-a4. The inclusion is almost always beneficial to Black.

In terms of theroretical value the GPA is not "refuted" if Black holds back d7-d6. It´s only that is doesn´t promise White very much. White has to play very carefully not be be worse. Then again there are many dangerous lines which ultimately prove to be insufficient but can surprise the second player over the board. Hey, if somebody plays an incorrect Gambit like the Blackmar-Diemer, why refrain from playing the GPA even without Black´s d7-d6?

After 2...d7-d6 Black might be able to hold his own in the GPA but at least it is very dangerous for him and after all much better for White in comparison to lines where Black can play d7-d5 in one move.

Yes, I have also thought of this. Something like 5.Bc4 a6 6.d3 b5 7.Bb3 Bg7 8.o-o e6 9.f5 gxf5 10.Kh1 Nge7 11.Ng5 h6 12.Nxf7 Kxf7 13.exf5 and the bishop is better on b3 than on c4. As soon as I have time, I will investigate this systematically.

The Hodgson game did feature the standard ..h6 response but I forgot about one important detail.  In that game Black played exf5 instead of gxf5.

Here's another thought though.  After 1.e4 c5 2.Nc3 d6 3.f4 g6 4.Nf3 Nc6 5.Bc4 a6!?, can White just ignore the possibility of ...b5 with 6.d3?  If 6...b5 then 7.Bb3 might actually be bad for Black since he's spent 2 moves on ...a6 and ..b5 while White just has the extra Bb3 move.  Of course the inclusion of these moves might give Black additional resources but I don't think White's chances should be underestimated.

After 10.Qe1 the standard h6 looks strong to me.
The only real refutation in the GPA I know is 1.e4 c5 2.Nc3 Nc6 3.f4 g6 4.Nf3 Bg7 5.Bc4? e6 6.f5 Nge7.

Can White improve with 10.Qe1 trying to play along the lines of Hodson-Malisauskas, St.petersburg 1984?  Of course that was a long time ago and White's idea may have been refuted by now.  What are the other refutations in the move order with 2...d6?
