Sveshnikov or dragon harder to play?

Sveshnikov is trickier imho.

If I remember correctly, there was once a Sveshnikov book with the title, The Easiest Sicilian. Don't ask me about whether or not to believe it.

They are both tricky in different ways, I always found the Dragon, well the Yugoslav at least to be constantly on a knife edge and you could lose a game simply on prep alone. Whereas the Svesh kind of works in practice but looks terrible to the casual observer, you still need to know plenty of theory not to go down to lines like Bxb5 etc 

Sveshnikov is more complicated IMO, more positional factors. However, the Dragon can be double edged depending on who's playing.

 The Sveshnikov Opening:

please I want to learn the dragon opening

Did you see my last post (#8)? It shows the Dragon Opening. White and Black have to play exactly those moves for it to be the Dragon Opening. Play through those moves on the chess board in post #8. Now try and play through those moves on a proper chess board, without looking at post #8. If you can do that, you have learned the Dragon Opening! This is quite hard for a small kid, so maybe get an adult or a big kid to help you.

For beginners... the above variation of the Svesh is actually a line in the opening and not the starting point!

Not according to Burgess, but he's been wrong before... 365 chess has the following, which takes the line further! Are you thinking of what Burgess calls the Pelikan variation, and what 365 call the Pelikan (Lasker/Shvesnikov)?:

B33 Sub-variants:

• • Sicilian defence
    1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6

• • Sicilian, Pelikan (Lasker/Sveshnikov) variation
    1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5

• • Sicilian, Pelikan, Bird variation
    1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6 8. Na3 Be6

• • Sicilian, Pelikan, Chelyabinsk variation
    1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6 8. Na3 b5

• Sicilian, Sveshnikov variation
  1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6 8. Na3 b5 9. Bxf6 gxf6 10. Nd5 f5

The variation you posted is the Chelyabinsk variation. I have a bunch of stuff on the Sveshnikov it largely starts after e5 as far as I am aware although Black can still play Lowenthal Sicilian also after Nb5. I am fairly sure that the Pelikan is an old name for the opening

Tbh in the dragon all your opponent has to do is ram the h-pawn up the board with little understanding and if they're tactically better then you just have problems. In the Sveshnikov they have to outplay you positionally. Which do you think is more likely in your games? The dragon isn't a choice for me...

The Sveshnikov is sound, complex and positional but white gets nothing if black is booked up. Black is even better in many lines. However, not so with the dragon. White has too many options. Black must know countless counters to very simple white ideas. 

IM Lakdawala (wrote move by move on svesh) just told me last week that the Sveshnikov is the mostdangerous Sicilian for white to play against. Plus, after we look at what suits us - black’s positional understanding and counterplay is based on solid chess principles. The dragon is just an enigma to most players. It’s based completely on tactics. I’ve played every Sicilian you can shake a stick at but never the dragon... I’ve also had luck as white against both but the sveshnikov is just more complex For white than it is for black. 

It can come down to; do you like to fianchetto your dark squares Bishop? If so, try the dragon. If not, don’t even think about the Dragon.  

I think surely sveshniko is easier to play because you just need to keep the positional themes in that opening and the moves will come on their own.  Dragon as you said has a lot of theory. If you don't have enough time to study the openings then sveshniko is the best choice

I’m a new devotee to the Svesh, still have only considered the dragon... until I open one of the books, then I give up. 

Mal_Smith: The original name of the whole complex is 'Lasker-Pelikan Variation'. Lasker essayed it against Schlechter in the WC match in 1910. Then Czech master Jiri Pelikan did quite a lot of work in the 40s and 50s (hence 'Lasker-Pelikan'), before Yevgeny Sveshnikov and Gennady Timoschenko broke a lot of new ground.
