I would like to play sicilian as black. Here on RHP I do and it is not problem due to opening databases, but what to do in OTB after e5 c5 Nf3 d6 when my opponent, often strong player leaves opening book but in way that cramps my position it happens all the time. Since that moves are out of opening book it should be easy to handle for someone strong, but I am not on the level to exploit his moves out of opening book if they do not have any obvious weakness. I hate strong players out of opening book.
But this problem is particular in sicilian, so I often lack in development and have to handle stupid situations and all I wanted to switch to dragon, najdorf or something more or less familiar. What is yours antidotte?
