Two knights defence, a variation

1. e4  e5 2. Nf3  Nc6 3. Bc4  Nf6 4. Ng5  d5 5. exd5  Nxd5 6. Qf3

A possible continuation is:

6. Qf3  Qxg5 7. Bxd5 Nd4 8. Qxf7+

This seems to be a disadvantage for black. So what should black do after 4.Ng5     ?
Is two knights defence always bad for black?

Thanks.

why don't you just play 5...b5 or 5...Na5

Note: look at the opening the rest is confusing

According to Fritz, Black has the advantage here. So, it seems white has no advantage after 8.Qxf7+

What do you think? Regarding your line, my engine thinks it isnt a better line than the above line.

I am not understanding the 6.Qf3 move which loses a piece for nothing over the well known Fried Liver Attack (6.Nxf7) and the Lolli Attack (6.d4).

Conquistador: I agree. It seems 6.Qf3 is not a good move for white.

Thanks.

You can look at wikipedia too:

How does Qf3 lose a piece?
