I was playing with the Black pieces online today, and faced a very strange opening:
[fen ""] 1. e4 e5 2. Nf3 Nc6 3. d3 Nf6 4. Be2
I check the database, and it seems that 4...d5 is good for black but I didn't understand the strategy behind it at all. Here are a few moves from the database:
[fen ""] 1. e4 e5 2. Nf3 Nc6 3. d3 Nf6 4. Be2 d5 5. Nbd2 Bc5 6. O-O O-O 7. c3 a5 8. Qc2 Re8 9. b3
I don't understand what Black is playing for here. Like what the plans are. I would really appreciate some feedback or references where I can read more about it. My understanding is that the Black pieces look like a position from an Italian opening. But I felt that the Italian plans don't work here tactically (like maneuvering Nc6-e7-g6).
I'm also open to other suggestions, such as playing 5...g6 (but I also didn't understand the plans behind it in this position).
