Chess Opening Theory/1. e4/1...e5/2. d4/2...exd4/3. c3/3...dxc3/4. Bc4/4...cxb2/5. Bxb2/5...d5

Danish Gambit Accepted: Schlechter Defence
By playing 5...d5, Black aggressively strikes back at the center, releasing the bishop to catch up in development, returning a pawn in the process. White main move is 6. Bxd5, and the main continuation is 6...Nf6 7. Bxf7+ Kxf7 8. Qxd8 Bb4+ 9. Qd2 Bxd2+ 10. Nxd2 with an equal position.

Alternatively after 6. Bxd5 Nf6, 7. Nc3?! is tried, but after 7...Nxd5 8. Nxd5 Nd7! (8...c6?? 9. Nf6+ gxf6 10. Qxd8+ Kxd8 11. Bxf6+ and White wins an exchange) Black has an advantage as he is still up a pawn and has the bishop pair, but accurate play is needed.

Note that 6. exd5?! is inaccurate because the bishop on c4 is now blocked by its own pawn. After ...Nf6 and ...Bd6, Black's king is safe and White does not have compensation for Black's extra pawn.
