Sicilian Accelerated Dragon (B34-B39) - Opening Theory

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6

Wikipedia's Definition of this Opening

Like the standard Dragon Variation, Black develops his bishop to g7 in the Accelerated Dragon. The difference is that Black avoids playing ...d7-d6, so that he can later play ...d7-d5 in one move if possible. For example, if White tries to play in the style of the Yugoslav Attack with 5.Nc3 Bg7 6.Be3 Nf6 7.f3 0-0 8.Qd2, 8...d5! equalizes immediately. When White does play 5.Nc3, it is usually with the idea of continuing 5...Bg7 6.Be3 Nf6 7.Bc4 0-0 8.Bb3 (forestalling any tricks involving ...Nxe4 and ...d5), followed by kingside castling.

The critical test of Black's move order is 5.c4, the Maróczy Bind. White hopes to cramp Black's position by impeding the ...d7-d5 and ...b7-b5 pawn thrusts. Generally, this line is less tactical than many of the other Sicilian variations, and play involves much strategic maneuvering on both sides. After 5.c4, the main line runs 5...Bg7 6.Be3 Nf6 7.Nc3 and now 7...0-0 or 7...Ng4 is most frequently

Ruy Lopez - (C70) Norwegian Defence or Wing Variation (Opening Theory)

The Norwegian Defence (also called the Wing Variation ), is an aggressive but time-consuming alternative for Black. The game follows 3...a6 4.Ba4 b5 5.Bb3 Na5. The goal of the opening is to eliminate the white bishop. A speculative sacrifice (Nightingale Gambit) is now 6.Bxf7+?!, which drives the black king out, but with accurate play, Black is supposed to be able to consolidate his extra piece.
