As black, I always play the Sicilian against e4. I personally like the Scheveningen system but to avoid the Keres Attack, I play a6 before e6:
[FEN ""] 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6
In that sense, the opening can also be named as Najdorf variation.
But I generally avoid playing ...e5 and prefer ...e6. I avoid ...e5 because I feel like playing ...e5 weakens the d5 square.
My desired set up is to have:
- Bishops on b7 and e7
- Knights on f6 and d7 (or c6)
- Pawns on a6, b5, e6, d6
- Queen on c7 (b6 or sometimes a5)
My general plan is to play d5 to open up the game for my white bishop at b7.
Now I have 2 questions:
- Sometimes (especially in closed Sicilian games) against black's ...d5 white can move their pawn to e5 and so creates a pressure on my king side. In those cases I have the tendency not to play ...d5 but then my white bishop can get stuck so becomes a bad bishop. Should I allow e5 with ...d5 and do something after e5 or should I think doing a move different from ...d5?
- Secondly, sometimes white pushes their pawn to c4 to block my ...d5. What could be a good strategy for black after c4?
PS. I generally prefer open Sicilian games to closed Sicilian games with maybe one exception. The exception is the variant where both sides make fianchettos on the g-file (like English opening with sides reversed) where the black has pawns on g6-e6-d6, black bishop on g7, knights on e7 and c6.
Then my strategy is to play Nd4 in order to exchange knights, making a queen side pawn rush by putting my rook to b8, and defending a possible g4 by moving my pawn to f5.
Can I apply that kind of play/strategy against white where white does not make a fianchetto with his white bishop where the game is a closed Sicilian game, (e.g. 1 e4 c5 2 c3... ) to overcome the problems that I described above.
