KID? Sicilian Dragon Yugoslav attack 9.Bc4? Dutch Leningrad? any other sharp line?

Almost all Benonis are sharp, I think

Among those I know:

- main line of the ...Nc6 KID with Mar del Plata centre.

- the Armenian variation of the French (no joke, it's bloody)

- some variations of the Nf6 Tarrasch French

And I guess Sicilian afficionados will be able to give you answers regarding it.

Wilkes-Barre.

Well that was an accident, I accidentally clicked delete rather than edit, there seems to be no "undo" feature, and my back button refreshed the page. I'm not typing it all again. Maybe later.

Perhaps King's Gambit?

Traxler Counter Gambit

1)Botvinnik variation of semi slav

2)Winawer poisoned pawn 

3)Perenyi attack in najdorf sicilian 

4)Najdorf poisoned pawn 

5) 9.Ne1 Ne8 variation of Mar der plata 

How accurate is my list? 

The anti Moscow gambit and the 9.Bc4 variation of the dragon are also good contenders 

Black can have a quiet game in the KG with the King's gambit declined and in case of the Schleimann gambit White can play 4.d3

Pretty accurate, but I think you mean 9. Ne1 Nd7 and you could also add the Yugoslav Attack of the Sicilian Dragon.

I think that he is talking about this variation

Possibly. I had no idea Ne8 was so well researched. Let's include both Nd7 and Ne8 in the list.

If I remember correctly, the old fashion way to answer 9.Ne1 Ne8 in the Mar del Plata centre KID was 10.Ne3 followed by 11.f4!? since 9...Ne8 gives up control of the c5-square and the e5-square in comparison with 9...Nd7.

From White perspective, this "dusty" way to play (by now) may be a good surprise weapon and the position then is not so sharp than in nowadays mainlines with Black's kingside attack.

Black can launch a kingside attack in 9...Ne8 variation too

Of course they can launch a kingside attack with closed center too, but not in the old fashion 11.f4 variation.
