This is not a Grand Prix. White is using a tricky move order against you which does not commit to f4.
Most of your opening moves are plausible. Even the end position doesn't look terrible for you, play 12...Qb6 and if he doubles your f pawns, ..Kh8, ..Rg8, and possibly ..f5. White does appear to have the upper hand though - as he expands on the kingside some of Black's pieces will look out of play.
For an improvement you may want to look at ...d7-d5, either on move 6, 9, or 10.
I think you're right. Maybe d7-d5 on move 9 works well. I don't think it's so good on move 6, as it's a bit premature, especially if white plays 6.0-0 instead of 6.d3, then 6...d5 loses completely.
I actually dont think the position is destroyed. You can move the queen, let him take the knight and recapture gf. That is not unsavable.
Hm, maybe, although it seems harder to play as black like that. What should my follow-up plan be? Kh7(play h6 first) - Rg8 and attack down the kingside?
You can do. Certainly in the Richter Rauzer lines of the Classical Sicilian you frequently capture on f6 with the pawn. Central pawn majority, half-open file, bishop pair.
Without Kh7 though, nor h6.
After Bg5, I found that my position was destroyed... White threatened to play e5, winning my knight. If I moved my Queen, the Bishop takes on f6. If I play d6, white plays f4, still threatening to play e5 (Bxe4 doesn't work after f4 - the position is still bad). In the end, I played e5 which opened up his light squared bishop's diagonal, and I got destroyed.
Any help after Bg5? I played h6 but then Bh4 and it's still bad. Fritz recommends g5, but I don't know the theory for that, nor can I find it anywhere in my database, and it looks bad because it weakens the kingside.
Thanks
After 1.e4 c5 2.Nc3 White has chosen the Closed Sicilian variation.
A better question than: "...Any help after (12.) Bg5?..." is "What is a better move for Black after 3.Bb5?" The answer is 3...e6. The reasoning behind that move has to do with Hypermodern Chess Opening Theory to control the center. The Sicilian Defense in every variation is all about Black applying Hypermodern Chess Opening Theory. I will explain what I am writing about later on in other posts in your thread if you are still interested.
For now the important thing is to have the right perspective and look at after your move 2...Nc6 what is really the reason behind the move 3.Bb5. The explanation that follows has to do generally with 3 factors: Siege Warfare (restrain, blockade and execute the enemy), 2 Chess Opening Theories (Classical and Hypermodern), and pawn structure.
3.Bb5 has the purpose of restraining your queenside pawns (a7,b7,c7,d7) from advancing. Especially your pawn at d7, because it is the most important pawn on the queenside for controlling the center. The reason that pawn is restrained is because if it advances let's say to 3...d6 then White can play 4.Bxc6 bxc6 and Black is saddled with a loose doubled pawn complex (an exploitable static weakness.) Granted White has given up the "minor exchange" (exchanging B for N), which gives Black the advantage of the B-pair. But the loose double pawn complex weakness in Black's army is more than sufficient compensation. To sum up, there is an overarching principle in chess:
Winning chess is the strategically/tactically correct advance of the pawn mass. The main reason this is so is because pawns cannot move backwards.
