thanx alot guys,

i didnt mean as an occaisional back up to my dragon but as a fully alternative defense so i may surprise my opponents alittle.

I aim to try and have a quite wide repetoire because it keeps em guessing!

Im buying the Emms book today so thanx very much!!

PS it is Schevy, not shevy. The c is needed for upsetting foreigners who want to learn Dutch

The Accelerated Dragon is another good choice as an alternative Sicilian for a Dragon player, although make sure you like facing the Maroczy Bind pawn structures as Black (Tiviakov explains them well for both colours in his DVD on the Maroczy).

You can even consider 1.e4 c5 2.Nf3 Nc6 3.d4 cd4 4.Nd4 Nf6 5.Nc3 g6!? as a surprise weapon, since the strong 6.Nc6! occurs about only one-third of the time. Many of your opponents will duck the challenge with 6.Be3 so that they can transpose to an Accelerated Dragon, which they are familiar with. And even if the opponent does find 6.Nc6 bc6 7.e5, the position after 7...Ng8 8.Bc4 Bg7 9.Qf3 f5 10.Bf4 e6 is worse, but not ghastly for Black. I wouldn't recommend playing 5...g6 very often, but you could probably get away with it in a few games.

If you want to play the Najdorf/Schevy combo, the best book is Emms's Play the Najdorf Scheveningen Style.  Against Bg5, Emms covers ..Qc7, so if you want to play the PP instead, you will need another source.  Everything else is covered.  Note, though, that the Najdorf/Schevy is a complicated defense and it's a big undertaking to try to learn it, and then also to maintain it, if you're only going to use it as an occasional back-up to your dragon.
