Owen's Defence
[edit | edit source]3. Bd3
[edit | edit source]Defending the e4 pawn. Black can now play:
- 3...Nf6, further pressuring e4.
- 3...Nc6 when 4.Nf3 is met with Nb4 getting the bishop pair, or if 4.c3 e5!?
- 3...e6, preparing to develop the kingside.
- 3...f5? threatens to take on g2 should white play exf5, trapping and winning the h1-rook, but this is a gross error: 4. exf5! Bxg2 5. Qh5+ g6 6. fxg6 Nf6?? 7. gxh7+! Nxh5 8. Bg6#.
- 6...Bg7 is better but still lost for Black after 7. Qf5! Nf6 8. Bh6 Bxh6 9. gxh7 Bxh1 10. Qg6+ Kf8 11. Qxh6+ Kf7 12. Nh3.
