## Kevin Goh's review on The Hyper Accelerated Dragon by Raja Panjwani
# The Yugoslav-style approach: 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.Nc3 Nc6 6.Be3 Nf6 7.Bc4
7...O-O 8.Bb3 a6!? {//extremely rare, recommended in chapter 2 "My System"}
7...Qa5 8.O-O O-O 9.Bb3 d6 10.h3 Bd7 {//7...Qa5 recommended in chapter 2} {The critical position}
11.Nf3 b5! 12.a3 Qa6! {//11.Nf3 a relatively rare line but it is one of the top choices of the machine.}
{11...b5 Novelty} {12...Qa6 the obscure idea of rerouting the queen to the b7-square where it can multi-task
on matters in the centre and on the queenside. None other than Hou Yifan had fell for}
11.Qd2? Nxd4 12. Bxd4?! Nxe4 -+ {//11...Nxd4 Black quickly seized the advantage } {12...Nxe4 0-1 (70)
Hou,Y (2584)-Bacrot,E (2721) Villarrobledo 2009}
11.Re1 {most critical. Panjwani covers 4 other alternatives, e.g. 11.Nf3, 11.Qd2 }
11...Rac8 { Panjwani compared it with 11...Rfc8}
11...Rad8!?
12.Nxc6 bxc6 { quite nice for Black}
12.Nf3 Qh5!? {//12...Qh5!? Panjwani: This move is a recurring theme in this Nd4-f3 variation.
Black intends to continue with ...h7-h6 and ...g6-g5 with counterplay against White's king.}
13.Nd5!? Nxe4 14.Bc1 Nf6 15.Nxe7+ Nxe7 16.Rxe7 a5! 17.c3 Bc6 18.Nd4 Qxd1+ 19.Bxd1 Rfe8=
{16...a5! accurate, perhaps White only has a nominal advantage}
13.Qe2 {//covered}
13.Rb1!? {//strange looking. covered}
12.Nd5
11...Rfc8!? {likely to be Black's best option}
12.Qe2 Qh5!? 13.Nf3 h6!? 14.Rad1 g5! {//Panjwani recommended this ...Qh5, ...h6, ...g5 theme}
15.e5!? dxe5 16.Ne4 Nxe4 17.Rxd7 Nd6 {//16.Ne4 computer suggestion. Unknown}
15.Nd5 Nxd5 16.exd5 Ne5 { comfortable for Black}
16.Bxd5 Bxb2 17.Rb1 Bc3 18.Rxb7 Bxh3 19.Nxg5 Qxe2 20.Rxe2 Bg4 21.Nf3 e6 22.Bxc6 Rxc6
23.Bxh6 Rb6! {//23...Rb6!N Panjwani suggests, improving on the game Carlsen-Radjabov}
12.f4 Nh5! {//12. Panjwani think this is under-rated} {12...Nf5! unusual but pretty strong}
12.Nd5 Re8 13.Nxc6 {//12...Re8 Novelty. This switchback is difficult to see, have to memorize.}
13...Bxc6 {//1-0 Smirnov, A (2508)-Favarel, A (2357) Anogia 2017. Black seems fine}
13...bxc6 14.Bd2 Qd8 15.Nc3 c5 16.e5 dxe5 17.Rxe5 c4 18.Bxc4 Qc7 -+{//}
# The Maroczy Bind 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.c4 Nc6 {// Ch4 & 5}
The quirky 6.Nc2 variation {//Peter Heine Nielsen recommended in Experts vs the Sicilian}
6...e6! 7.Nc3 Nge7 {//6...Ne6!? with the idea of ...Nge7 and a quick ...f5 break.}
8.h4 {//seldom turns out well for White}
8.Bg5 O-O 9.Qd2 Qa5 10.Bh6 Bxh6 11.Qxh6 f5!? 12.f3 fxe4 13.fxe4 Qe5 14.O-O-O Qf4+ 15.Qxf4 Rxf4
{//11...f5!? counterplay. Black kingside a bit fragile. End in dynamically equal}
8.Bf4 O-O 9.Bd6 f5 10.exf5 Rxf5 11.Bd3 Rf7 12.O-O b6 13.Ne3 Bb7 14.Re1 Rc8 15.Rc1 Nf5 16.Nxf5 gxf5
{//both have chance}
The main line 6.Be3 Nf6 7.Nc3
7...Ng4 {//Panjwani recommends it as a secondary line, still, Black is a little passive}
7...O-O 8.Be2 d6 9.O-O Bd7 10.Qd2 Nxd4 11.Bxd4 Bc6 12.f3 Nd7 {//the main line. //9...Bd7 extremely popular.}
{10.White has many options, e.g. 10.Nb3, 10.Rc1, 10.Nc2}
{12... there are some dangerous lines, e.g. 12...Bd3, 12...Rfd1, 12...Qe3}
13.Bf2!? a5 14.b3 Nc5 15.Rab1 e6 16.Rfd1 Be5 17.Nb5 Bxb5 18.cxb5 {//13.Bf2!? rare, novelty}
18...Qe7?! 19.b6! {//18...Qe7?! Panjwani's main move, Black will play Qe7 and b6, so Panjwani thinks
moves order does not matter //19.b6! But Goh is worried about this Computer-ish move make White better}
19...Rfc8 20.Rbc1! Rc6 21.Be3! Rxb6? 22.f4 Bg7 23.e5+19...f5 20.exf5 Rxf5 21.g3 +=
19...Qd8 20.Rbc1! Qxb6? 21.f4 +18...b6!? {//18...b6!? may be most precise}
19.a3 a4 20.b4 Nb3 {//Black has permananet foothold. Equal position}
19.Rbc1 Qe7 {//Qe7 and b6 done.}
20.g3!?
20.Qe3 Rad8 21.g3 {//Goh's preference}
20.Qe3 Rad8 21.f4 {//Panjwani's preference. White slightly advantage. Black remains active.}
13.Be3 a5 {//the top choice of the HAD}
14.Rab1 Nc5 {//14.Rab1 covered}
14.b3 {//top choice. Panjwani recommended ...Be5, ...e6 followed by ...f5 or ...Qf6}
14...Nc5 {//top choice. Panjwani covered all rook moves, e.g. 15.Rfc1, 15.Rac1, 15.Rfd1}
15.Rab1 Qb6 16.Rfc1 Rfc8 17.Bf1 Qb4 18.Qb2 Qb6 19.Kh1 Qd8 20.Qd2 e6 21.Bg5 Qf8 22.Rd1 h6
23.Be3 Rd8 24.a3 {//Wang Hao(2702)-Bu Xiangzhi(2710) China 2017, 0-1. From moves 15 to 20 they wasted few
moves before finally come to 20...e6, White was slightly better}
15.Rab1 e6 16.Rfd1 Be5 {//White slightly better}
