Chess Opening Theory/1. e4/1...c5/2. Nf3/2...d6/3. d4/3...cxd4/4. Nxd4/4...Nf6/5. Nc3/5...g6/6. Be3

=Sicilian Defence, Dragon Variation= The logical continuation is /6...Bg7/.

Black might be tempted to play the trap 6...Ng4??, intending to chop off White's dark-squared Bishop, which would strengthen the Black Bishop soon arriving at g7. But this is a beginner's mistake, it loses horribly to 7.Bb5+:
 * 7...Nd7 8.Qxg4 wins a Knight
 * 7...Bd7 8.Qxg4 also wins the Knight, since the Bishop on d7 is pinned
 * 7...Nc6 8.Nxc6 bxc6 9.Bxc6+, forking the King and Rook and winning the exchange and a pawn.
