I have  now played lots of  Correspodence Chess games the crititical lines in 9 0-0-0 and 9 Bc4 yugoslav systems proposed by Giris book. And my conclusion are that the Dragon is a long forced draw in both lines.

White might win some games in the 9 0-0-0 endgame in practical over the board games but objective the endgame is a easy draw,

This is realy fun all white repertour books, bases and videos goes for Bc4 while computer seems to prefere Be2 or Bd3 a clear indication that Morra is in big trouble.

I have not seen that post but he plays 1 e4 c5 2 d4 cxd4 3 c3 dxc3 4 Nxc3 Nc6 5 Nf3 e6 6 Bc4 Bb4 7 0-0 Nge7. Whites best is given as Nb5 when he returns he pawn with d5 and gets bishop pair advantage and white has no play. He also covers Qe2 etc. In general he avoids a6 and does not try to hold the pawn. Its low theory line.

Having analysed a bit now I start to think black position is holdable. I will try Giris lines over the board play and maybee even try it in Correspondence Chess in the future. Giris book has also very good lines vs anti sicilians as well particullary vs Morra Gambiit.

I had a brief look at Saric's chessable course "The Open Sicilian A Champion's Guide".
Here is his comment on a final position he recommends:
"Up to this moment, we were following the forcing line which is recommended by Giri in his Dragon course. White here has many ways to continue. Objectively, Black should draw this endgame, but the real question is how many players in the world can hold it."


While on the same position Giri's comment is
"And this position is of course a draw, although the computer rightly points out that Black still has to be precise. Some key lines:..."
The position:

On the other lines (12...BxBd4), Saric's says more or less the same: holdable but requires very precise play.

I'm not a dragon payer, just curious. I don't know if dragon players would agree, but my feeling so far is that creating winning chances in the yougoslav attack without Bc4 is not easy against a well prepared player (play seems more doubled edge and interesting against Bc4)and in any case it all comes down to a lot of work on some typical endings just to stay alive.

Knock knock!
Good evening everybody at least for the ones on EST time in the US.

I wanted to mention something I was suspecting. Recently a game between Stockfish 14 vs Lc0, TCEC Season 21 was uploaded to youtube. On the Variation 12.Kb1 Re8 white unleashed 13.h3 (a move that I already knew. The point is to hold back the h-pawn and be ready for a possible f4 as g4 is covered.) in that game black continued with 13...Qc7 and after 14.Bh6 Bh8 white played 15.h4 (as there is no longer 15...h5 to make it harder for white). After 15...Nc4 16.Qd3 Ne5 17.Qf1 Nc4 18.Bc1 Qc5 19.g4! white simply had a better game.

I myself had analyzed this position and concluded that maybe 13...Nc4 could be a better option. After 14.Bxc4 Rxc4 15.Qd3 Rc8 16.g4 looks better. But 15...Qc8 16.g4 Rxc3 17.Qxc3 Qxc3 18.bxc3 Rc8 19.Nb3 where after 19...Bb5 (19...Rxc3 20.Rhe1 h5 21.Rd3 Rc8 22.Bd4 Bc6 23.e5 dxe5 24.Bxe5 white looks better) 20.Rhe1 Nd7 black has some chances defending it.
Other possible options are 13.a3, 13.Rhe1, 13.Rhg1 and 13.g4

Below the PGN. Food for thought!!!

One last thing I wanted to mention is that you still need to study the Soltis after 9.Bc4 Bd7 10.h4 h5 11.0-0-0 Rc8 12.Bb3 Ne5 by transposition. And here 13.Kb1 Nc4 is the recommended move. But 13...Re8 would take you back to the 12.Kb1 line (9.Bc4 Bd7 10.0-0-0 Rc8 11.Bb3 Ne5 12.Kb1 Re8 13.h4 h5)

Happy 4 of July to all Americans!

9.0-0-0 d5 10.exd5 Nxd5 11.Nxc6 bxc6 12.Bd4 e5 13.Bc5 Re8 14.Ne4 Qc7 15.g4 is in the course. The text says 'Logical, stopping f5, but Black has a good version of things, as after 15... Be6 we have a theoretical position without the inclusion of h4 and h6. White will need to go h4 anyway, but we will no longer have to lose time on h6.' With some lines.

I didn't find the argument weird. Your counter-arguments are worth considering, but consider also this scenario: Tomorrow Giri starts playing the Dragon against other top players. Would this new fact increase your confidence in the chessable repertoire, decrease your confidence, or make no difference?

A suspicious mind, verging on paranoia, is a positive trait for a chessplayer. The reason why a Dragon player might be suspicious that some blithe Dragon analysis will not hold up in practice is because they have seen it before. I am sure Giri knows a lot, and is a good analyst. What trips up an author in an opening they don't play is the lines they don't know and haven't analysed. In a sharp opening such as the Dragon, you want the author to be a fellow practitioner because they will have an eye for alternatives that need checking. There is also the classification of opening problems into those which can be figured out at the board, and those which can't. Here again, the practitioner of an opening is much more likely to know which is which.

I have been putting some dedication to the line with 9.Bc4 Bd7 10.0-0-0 Rc8 11.Bb3 Ne5 12.Kb1 and 12...Re8 seems to hold it. But it is super complicated and you have to be ready to play variations such as 13.h4 h5 14.g4 hxg4 15.h5 Nxh5 16.Bh6 Kh7 17.Bxg7 Kxg7 18.fxg5 Nxg4 19.Nf5+ Bxf5 20.exf5 Rh8 21.fxg6 Nxg6 and here one of the lines goes 22.Nd5 Nf6!23.Rxh8 Qxh8 24.Qg2 Qd8! 25.Nf4 Qe8 26.Rg1 Qc6 27.Ne6+ Kg8 28.Qg3 d5 29.Nf4 Qd6!

Also there is a deviation with 16.Rdg1 Qa5 where after 17.fxg4 Bxg4 18.Rh4 Rxc3 19.bxc3 Nf6 20.Bh6 Nxe4 21.Qe3 Nxc3+ 22.Ka1 Bf6 23.Rhxg4 Nxg4 24.Bxf7+ Kh8 25.Qh3 Qh5 26.Qxc3 Nxh6 27.Bxe8 Qc5 28.Qxc5 dxc5 where with precise play black gets a draw.
Here 17.Bh6 Bf6 18.fxg4 Bxg4 19.Bg5 Bg7 20.Rh4 Rc4! seems to do the trick! Alternatively 20...Rc5 could be an option. But I didn't study it yet.

On 14.Bh6 Nc4! 15.Bxc4 Rxc4 16.Bxg7 Kxg7 17.Qe3 Qb6! seems to hold well after 18.Rd3 Rec8 19.Nd5 Nxd5 20.exd5 R4c5 21.Qe4 Qc7 22.Rc1 Re8 23.a3 e5! 24.dxe6 Bxe6 25.b3 b5 with equality. In this variation 17.Nd5 e5 18.Nxf6 Qxf6 19.Nb3! Be6! 20.Qxd6 Rec8 21.c3 R4c6 with compensation due to the bad knight and the activity of the black pieces.

I barely saw Giri's course. I wouldn't trust it. On 9.0-0-0 d5 10.exd5 Nxd5 11.Nxc6 bxc6 12.Bd4 e5 13.Bc5 Re8 14.Ne4 Qc7 he talks about 15.h4 f5. But what about 15.g4?
I do not recall to have seen Giri playing one single Dragon game. So you need to be careful with his material.

Kruppa-Tiviakov, 1991 is basically given although he stops short of the end. 14.Ne4 is where the original analysis starts.

A bit later comment on that opposite coloured bishops endgame was "And this position is of course a draw, although the computer rightly points out that Black still has to be precise. Some key lines:"  with some analysis to move 35-40.  The indication is that the current computers are able to analyse the position to a draw.  How easy it is to hold OTB is another matter, but it doesn't look impossible to me at first glance.

I'm not sure I'm really qualified but I would say they are far from final.  I believe that Giri has both deviated from his Najdorf course and beaten players who played his recommendations against him as white.  These are interesting new lines generated by a top playing pushing the current strongest engines on strong hardware, I'm sure in 5-10 years there will be some different ideas. Chess is not yet dead.

Giri thinks 9.Bc4 Bd7 10.0-0-0 Rc8 11.Bb3 Ne5 12.Kb1! is just better for white so 11...Nxd4 is mandatory, but rather than learn all the Soltis stuff as well (due to 10.h4 h5 move order) it is better to just play Nxd4 earlier.

For the Kaufman line, Giri basically follows it to the end and says black is fine.  Kaufman was claiming +0.14 of an advantage so I would say that is OK...

Lifetime repertoar and in Dragon looks like an odd combo but since Bc4 recommendation is a side line it might work.

About 2 Nc3 g6 there are some lines you must know after 3 d4. For example Kaufmanns book went for something that looks like a standard  yugoslav attack but with the Knight at e2 instead of d4 thus all theory are gone.

Sounds like += to me. Karpov in his heyday would have made it seem almost hopeless for black.

That does seem interesting.  In my awareness, 13...Re8 has been considered as leading to += since the '90s (including in the recent ECO-B2).
