Is the Sicilian Dragon too risky for Black?

Kan and Scheveningen

9 0-0-0 was the only reason I gave up on the Dragon. After 9...d5 (the only playable move), you just find yourself defending slightly worse endgames.

How so? IIRC the Accelerated Dragon is praised for saving time in positions like that because it allows d7-d5 in one move. Isn't that kinda the default plan?

Yes.

Does one necessarily get "positions like that" in the Accelerated Dragon?

There are few things to "understand" in the Dragon - the plans, compared to other Sicilian lines, are simple and straightforward. The real issue is the massive amount of lines one has to memorize.

Do things necessarily go according to plan?

When choosing to go for the Accelerated Dragon, does Black know what moves White will play?

"... the Yugoslav Attack is the ultimate test of the Dragon. … The Yugoslav Attack is perhaps the most theoretically complex line of all openings. General principles are useful, but in this opening there is no substitute for learning the seemingly endless amount of critical variations. If you wish to play the Dragon then you need to be thoroughly prepared for all of White's options in the Yugoslav Attack. This means a lot of hard work, …" - GM John Emms (2009)

"Generally speaking, 'Starting Out' and 'Sicilian Najdorf' are not exactly words that one envisions in the same title, because anyone who is just starting out should not dive into the vast ocean of theory that is the Najdorf. For beginners, the time invested in studying even minor lines can be more productively used solving tactical puzzles and basic endgame technique.

... In some lines, a good understanding of basic principles will take you far, while in others, such as the Poisoned Pawn (6 Bg5 e6 7 f4 Qb6!?), memorization is a must, as one wrong move can cost you the game in the blink of an eye. ..." - FM Carsten Hansen (2006), reviewing Starting Out: Sicilian Najdorf

The Dragon is completely playable despite its risk. It does not “lose by force”. Also, 9...d5 is what I would probably say is black’s best, but not only playable option in response to an earlier post. 9...Nxd4 10.Bxd4...Be6 is completely playable as is 9...Bd7.

the whole Sicilian is bad for black e5 is safe choice

Arguably refuted. In the mainlines the best you can hope for is draw. Though some of the lines are unclear, not enough to keep white from getting the upper hand.

2...e6 the french variation, has the same = eval, but slightly better winning stats 1600-2000 @ 46:50 in the 57% main line vs 48:47 @ 57% in the modern, leading to dragon variation with strong performance in 2 out of the 3 next main lines

the deeper into sidelines white goes, the better black does in that variation

1. e4 c5 2. Nf3 e6

3. d4 cxd4 4. Nxd4 Nf6  44:52 @ 3m +0.4

3. c3 Nf6 4. e5 Nd5 5. d4 cxd4 6. cxd4 b6  40:54 @ 45k +0.3

3. Bc4 d5 4. exd5 exd5 43:53 @ 1.2m +0.2

3. Nc3 a6 4. d4 cxd4 5. Nxd4 Qc7  41:55 @ 2.4m +0.2

doing quite well in every main line

black does poorly in the main line after 3.d4 cxd4 4.c3 dxc3 54:42 @ 600k -0.2

Wdym the Dragon is a forced win for black that's why nobody plays open sicilian anymore are you not up to date with the recent events in chess?

can you confirm that the Dragon is indeed a FORCED win for black?

He's just a troll.

Yes. After black plays the standard dragon tabiya, white is forced to resign because you never know what will happen with insane people, and it’s better to value one’s own life.

The mythical power of the dragon lives rent free in the opponent's head and hence he trembles with fear while facing the dragon. Black players don't want every game to be one sided and that's the reason they left the evil power of the dragon behind.
