Fried Liver Attack Defense

It's not bad, but there is a minor flaw.
White can play a solid piece up. Even if there is no 6... Nxd5, white still has a pawn up on black.
It would probably actually go more like 6... Nxd5 7. cxd4 Qxg5 8. Bxd5. Sorry about that, messed up on the diagram. The trap is a nice idea for blitz though.

But you see the enemy won't embark into uncharted waters and accept the decoy, when he can be in full confidence the FLA wins by force.

d6 is a horrible move in this situation. Any player with white pieces would not do that when he sees how strong it is for black. It is better for white to castle or move d3 to start developing and defending the knight on b5.

Meh, white loses faster like this.
What the HELL? No! No!! NO NO NO. Ooooogggggllyyyyyy. N x Q ?

That first little trick is pretty awesome though. I don't think it would be uncommon for white to just play c3 though. I dunno. I'll try it out. Thanks for sharing.

After c3 it's very important for black to play b5, driving the bishop back to f1 to defend the g2 pawn.
Very famous game in this line is here: (b5 is actually played first in this game, but in a few moves the same position is reached)

5...Nd4 is the Two Kts Game, Fritz Variation, which is often interchangeable with 5...b5 the Ulvestad Variation.
5...Nd5 6.d4 is the Lolli Variation.
5...Nd5 6.Nxf7 is the Fried Liver Attack, an Italian idiom (Fegatello) meaning "in hot water"

Thank God someone finally said this. I am running out of hair to pull out from these misconceptions.

i know it's bad. i'm just showing you that now white cannot play d6 once the knight is on f5
