Openings dissected part 1: Qf3 two knights

8.Qf3 is a weak move for white.
After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Na5 6.Bb5+ c6 7.dxc6 bxc6 8.Qf3 h6! and black has a strong attack.
Simply 9.Ne4 Nd5 10.Nbc3 cxb5 11.Nxd5 Bb7 12.Ne3 Qd7 13.0-0 Nc6 14.d3 0-0-0 and black is better.
That's interesting. 8... Bg4 has no games in the Shredder Opening Database. The most common move is Rb8 and the most frequently winning move is Be7.

The two knights defense is a very popular defence for black. Although it is a gambit it allows black to take the iniative and play exciting chess. White's main goal is to get black out of "book," thus black's attack won't be as strong.
For those who don't know the possition above is the two knights defence. White has two options the possitional aproaches d3 and d4 or Ng5. I will talk about Ng5. The variation below is then the main line, I will mention when their are alternatives
