I am looking at this game and saw this opening.
[FEN ""] 1.e4 e5 2.d4 exd4 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Qh5+ g6 6.Qd5+ Kg7 7.Qxc5
The 3.Bc4 is new to me. I think people usually play 3.Qxd4. So, my questions are:
- What is the idea behind 3.Bc4? Simply put pressure the f7 square?
- It seems that 3. ...Bc5 allows White to sacrifice the bishop because he could take a bishop back at 7.Qxc5. Are there any other reasonable moves for black after 3.Bc4?
I am a beginner in chess, so a more detailed explanation would be much appreciated. Thank you in advance.
