Foreword by Jeremy Silman "Many chess players do ηοΙ have the Sicilίan ίη their repertoire because they consider ίι ιοο sharp. The system Ivanchuk opts for is quite an exception, as ίι is based οη profound positional ideas." (Piket explaining why Ivanchuk used the Accelerated Dragon). Back ίη 1981 Ι met a young chess fanatic named 10hn Donaldson. After a bήef mutual fascination: we both had a deep love for the Accelerated Dragon. After analysing for several hours, we decided that someday we would get together and write the ultimate book οη this opening. Ιι took nine years, but we finally ρυι fingers Ιο keyboard and started to act οη our dream. Now, several years after the appearance of the first edition, both 10hn and Ι are ccstatic Ιο see world-class players such as Anand, Kamsky, Ivanchuk and PίkeΙ making use of Όαι' system. This new interest ίη the Accelerated Dragon, and all the thousands of games that form the result, made a complete rewrite of our earlier work a necessity. This book is ηοΙ a 'winning repertoire for Black' tome. Ιι is an honest appraisal of an entire opening system. We admit Ιο having emotional ties to the black pieces, but we made a poinΙ of oνeπidίnB our baser desires and giving an impartial view ο! each and every variation. Though ηο book has ever given so much mateήal οη this line, we must admit that we could easily have filled several hundred extra pages with the games that eventually got cut. Nevertheless, the variations are still covered with such thoroughness that the sheer mass ο! information may actually become rather daunting! This type of depth will serve the 1Μ and GM very well. However, the average tournament player also has a 10Ι Ιο gain from this book; this opening is a perfect weapon for the Swiss-system waπior. It's full of traps and is positίonally wellfounded. Ιι was with the average player ίη mind that we added the section οη plans and we went ουΙ of our way to intersperse explanation ο! the relevant ideas with the actual moves in each variation. Α quick word οη the Semi-Accelerated and Hyper-Accelerated Dragons. These systems are attempts by Black to avoid the Maroczy Bind. Though they succeed ίη doing this, new problems arise that give the game a completely ditIercnt slant. There is a lοt of room for οήgίnal thought here and Ι hope that a few readers give these lines a try. Any questions, new ideas, or CΉticisms should be addressed to the publisher; these will then be forwarded Ιο us.

Accelerated Dragon is essentίally an attempt Ιο improve οη the regular Dragon (1 e4 c5 2lDf3 d6 3 d4 cxd4 4 lDxd4 lDf6 5 lDc3 g6) by aίming for the break ...d7-d5 ίη one move instead οί two ( ... d7-d6 and later ... d6-d5). Whίte can try Ιο restraίn thίs advance either by using hίs pieces (lDc3 and ~c4) or by settίng υρ the Maroczy Bind with c4. After 5 lDc3 ~g7 6 ~e3 lDf6, if Whίte plays 7 ~e2 0-0 8 0-0- Black realίzes hίs aίm with 8 ... d5! and gaίns instant equalίty. For thίs reason Whίte must ρυι hίs bishop οη c4, i.e. 7 ~c4 (ίη place of 7 ~e2), controlling d5, if he wishes Ιο fight for an advantage. Thίs allows Black the optίoη of transposing ίnto the heavίly analysed Yugoslav Attack of the Dragon with ...d6, but Accelerated Dragon players have two interesting alternatives ίη the positίonal 7 ...•a5 and the tactίcally promίsing 7...0-0 8 ~b3 a5. The ΜΙ, 7 ...•a5, forces Whίte Ιο castle kίngside due to the fact that 8 f3 (and certaίnly ηοΙ 8 .d2? lDxe4! 9 lDxc6 .xc3!) can be met by the neat tactίcal refutatίon 8...Wb4 9 ~b3 lDxe4 10 lDxc6 ~xc3+ 11 bxc3 .xc3+ 12 ~e2 dxc6 13 .td4 e5 !. With both sides castlίng short, play becomes much more positίonal than ίη the Yugoslav

Attack. Whίte aίms for kίngside play and the thematίc lDd5.

DiagramA Diagram Α shows the type of posithat Black must strίve to avoid. Whίte has played lDd5 and exchanges οη that square have led to the opening of the e-file and subsequent pressure agaίnst Black's pawn οη e7. Το make matters worse foι Black, Whίte is about to launch a kίngside attack with h4-h5 followed by either h6 or :h3. Το obtaίn a good game Black must play energetically οη the queenside (see Diagram Β). Ιη thίs position Whίte is about Ιο attack Black's knίght with f2-f4.

Black's plan is clear: he ΜΗ play ...:fb8 and force White to advance hίs b-pawn and then he wi1l train hίs sights οη the c-pawn and force ίι to advance as we1l.

Devised by the Lithuanian coπespon dence player Uogele, 8 ...aS aims at softening υρ the al-h8 diagonal for Black's fire-breathίng 'Dragon' bishop. If permitted, the black a-pawn will advance Ιο a3 and undermine White's knight οη c3. Το stop thίs, White usually plays 9 f3, bοlsteήηg his e-pawn. lι was Uogele who first appreciated Ιhat after thίs move, whίch leaves Whίte's bishop οη e3 unprotected and weakens his king-positίon, Black has ιhe strong rejoinder 9...dS!. Αι first glance, thίs move seems outrageous since ίι leaves the pawn open ΙΟ capture ίη ηο fewer than three different ways. Ιη fact, ίι is deeply thought-out and entίrely logical. Ahead ίη development (White is stίll ηοΙ casΙled), Black sacrifices a pawn for acιίνe play. Theory has yet Ιο discover a way for White Ιο obtain more than a microscopic plus against the Uogele. Some memοήzatίοn is involved but if Whίte is even slightly unfamiliar with Ihe analysis he can get brutally crushed ίη just a handful ofmoves. When confronted with the Acceler"Ιcd Dragon, most GMs ορι Ιο avoid ιhe tactίcal play arising from 5 ltlc3 tlnd instead choose a positίonal course with 5 c4.

Dark square domination and/or good knight νs bad bishop BIack's final plan Ιο 'unbind' the 'hind' is to play οη the dark squares. This strategy serves as the cornerιόΙοne of two major systems: 1) 1 e4 c5 2 lΩf3 lΩc6 3 d4 cxd4 4 lίJxd4 g6 5 c4 ~g7 6 ~e3 lΩf6 71Ωc3 li)g4. 2) 1 e4 c5 2lΩf3lΩc6 3 d4 cxd4 4 ~xd4 g6 5 c4 ~g7 6 ~e3 lΩf6 7lΩc3 ο-ο 8 ~e2 d6 9 ο-ο ~d7. Ιη both lίnes Black strives Ιο trade "11 Ιhe minor pieces except White's lίght-squared bishop and a blackknίght 10 cnd up with the classic 'good knight Υιό bad bishop' advanιage.

for both sides

Thίs positίon is typical of the type of thing that Whίte must avoid at all costs, and Black should play for ίι from the begίnning. It's qUΊte obVΊous that the nίmble knίght (whίch is happy where ίι stands, though ίι can also go Ιο b4 or, after ... e7-e5, Ιο d4 via e6) domίnates the sickly bishop!

Τactical Τhemes ίn

the Accelerated Dragon Ιη the Accelerated, Black's main tactί cal ideas are based οη hίs potentίal pressure against the d4-square. Thίs square often plays a major role ίη Accelerated Dragon skίrmίshes. Many tίmes Black's fianchettoed bishop, c6-knίght, and queen wreck havoc οη Whίte 's position. For example: 1 e4 c5 2 lΩf3 lΩc6 3 d4 cxd4 4 lΔxd4 g6 5 1Ωc3 ~g7 6 ~e3lΩf6 7 ~c4 0-0 8 f3? .b6! 9 ~b3 lΩxe4! (diagram G) 10 fxe4 .txd4 and Black has won a pawn.

Recently this has become very popular. Though the double advance ofthe a-pawns is ίη Black's favour (as axb3 is ηο longer possible), White is demonstrating that things are ηοΙ as easy for Black as theory had once supposed. One of the biggest changes since the publication of the first edition of this book is the reaρpraisal of 9 a4. Formerly, Black was considered to be doing extremely well after 9...~g4 1Ο "xg4 ~xd4 followed by capturing οη b3 mixed with a quick ... d6 and ....te6.

8 Maroczy Bind: Gurgenidze System The Maroczy Bind, once considered to be a refutation of the Accelerated Dragon move-order, is one of White's very best set-ups. ΒΥ gaining space and clamping down οη the dS- and b5-squares, White makes ίι hard for Black to find active counterpIay. There are several ways to meet the Maroczy, but the Gurgenidze has turned ίηΙο Black's most popular and highly respected system. Favoured by active players such as Anand, Tiviakov and Petursson, the once dreaded bind has been shom of most of its terrors.

This system can have a 10Ι of sting if Black doesn't react energetically. White intends to fianchetto his kίng's bishop, castle, and then restrict Black's pieces with moves lίke h2-h3 and a2a4. Once this is accomplίshed he WΊll continue WΊth /ί)d5 and, ίf Black takes the beast, then exd5 wίll enable Whίte Ιο generate pressure down the open efile agaίnst Black's e7-pawn. Though 6 ...d6 is the most common reply, we wίll only look at 6 ... 1ί)f6 because that allows Black Ιο make the most of the Accelerated Dragon move-order (the positions after 6 ...d6 usually come about from a Dragon move-order and are thus outside the scope of this book). 6•••1ί)f6 7 g3 bS!

TakίηB the bώΙ by the horns. Black immediately stakes ουΙ some queenside space and guarantees himself plenty of play οη that side of the board.

g3 variation is to ρΙορ a knight οη d5, have Black capture it, then apply pressure down the e-file. ΒΥ being able to play ... ~d7, Black takes the sting out οί this idea. Moves like ...e6, ...J.b7 and ...~6-d7-c5 are qώte common in Black's set-up here. 12 c3 e6 13 ~b4 lαιb4 14 cxb4 ~b6 15 1Ib1 J.b7, Zso.Polgar-Vl.Georgiev, Matinhos 1994. The other thematic move is 10 h3 b4 11 ~ J.a6 (Black avoids ...d7-d6 and, by doing so, refuses to create a weak point οη c6) 12 lIel ~xd5 13 exd5 ~aS 14 .t.f4 1Σc8 15 d6 e6 16 a3 b317cxb3 1i'b618b4iα419b3~b2 20 iVd2 ~3 21 J.e3 iVxd6 22 lIadl 1i'b8 23 1If1 d5 24 J.h6?
