No! I've just started learning it. How can I sabotage your thread?
Grand prix is annoying

The grand prix is actually (in my opinion) not that effective. While it can be dangerous, it actually scores really well for black.
if you study it with an opening database like 365chess you should be ok

A lot depends on your line of choice in the Open Sicilian. What you play against the Grand Prix, Closed, and Open must mesh!
After 1.e4 c5 2.f4?! Black should play the Gambit line, 2...d5! 3.exd5 (3.Nc3 Nf6 is known as the Toilet Variation) Nf6 4.c4 and White's extra pawn is a backwards, extra d-pawn.
After 2.Nc3, intending 3.f4 (or 3.g3 in the case of the Closed Sicilian), you must select your line wisely.
The "Main Line" is 2...Nc6 and then 3.f4. However, if you are a Najdorf or Kan player, this is no good. If you play the Najdorf, you have to play 2...d6 or 2...a6. If you play the Kan, you have to play 2...e6 or 2...a6.
The 2...a6 idea is fairly recent (20 years maybe?). Black will follow up with 3...b5, 4...Bb7, and 5...e6.
The reason why it matters what you play in the Open Sicilian is that White can just as easily play 3.Nf3 intending 4.d4, as in 1.e4 c5 2.Nc3 Nc6 3.Nf3 d6 4.d4 cxd4 5.Nxd4 Nf6 6.Nc3 is a direct transposition to the 2...d6 Open Sicilian.
Well, if you are a Najdorf or Kan player, the Knight belongs on d7, not c6. So you have been tricked by move order. This is why what you play in the case of the Open Sicilian matters. If you play something like the Classical, or Taimanov, or Dragon, or Scheveningen, go ahead and play 2...Nc6. If you play the Najdorf or Kan, you have to play another line as White can still play an Open Sicilian and the Knight doesn't belong on c6 in the case of the Najdorf or Kan.

Actually, Black can go 2. Nc6 no matter what Open Sicilian he plays because after 3. Nf3...e5 White will not be able to transpose to the Open Sicilian.
