in the dragon part of the goal is to feinchetto,creating a nearly unbreakable black defence.
Two questions

The first diagram depicts a rare position that comes about in the Queens Knight Defence of the King's Gambit, where white plays 3. d3?!
The second position comes from the Phillidor Defence, where white plays 3. Nc3 and black plays 3... f5?!
So, to recap, the lines are:
First Position: 1. e4 e5 2. f4 Nc6 3. d3?!
Second Position: 1. e4 e5 2. Nf3 d6 3. Nc3 f5?!

Well, for your first question, I don't know those specific openings, but I know some that are close to them.
And there is such variety and a huge amount of theory in the sicilian, you're not going to get many good answers. In general, the sicilian player aims for open tactical games to minimize drawing chances.
Hi I have two questions... First one: Can people tell me what sort of openings these are? It's the same positions basically, but for white and black.
White:
Black:
It doesn't really matter what the opponent plays for the 3rd move (as black), I just want to know what this opening (specifically the 3.f4 or 3...f5) is called so I can study it further as I use it frequently, thanks!
Second question: Can someone tell me the theory behind the Sicilian Opening for black? What do I want to achieve from it? I'm interested in the Closed and Najdorf variations specifically.
Thanks again
