Budapest played correctly after 3.e3

Following on from the last post, here is a master level game I dug out which demonstrates how to play the opening correctly after 3.e3 and Black following up with 3. ... e4, as in my latest club game. This games shows how the strategy of initially attacking the Queen with a5 and Bishop on a4 result in a full scale attack against the castled King. The White Queen has to be sacrificed or a mate will surely follow ... The game ends with a neat Nf4 (to allow Nxf4 Qf3+ winning the Rook on h1)

1. d4 Nf6 2. c4 e5 3. e3 e4 4. Nc3 Bb4 5. Bd2 Bxc3 6. Bxc3 d5 7. Qc2 O-O 8. O-O-O Nc6 9. h3 Qe7 10. Qb3 Rd8 11. g4 h6 12. Bd2 a5 13. cxd5 Nxd5 14. f4 Ncb4 15. Bxb4 axb4 16. Ne2 Ra5 17. Kd2 Bd7 18. Ra1 Ba4 19. Qc4 Rd6 20. Qc1 Rc6 21. Qb1 Rc2+ 22. Qxc2 Bxc2 23. Kxc2 Nxe3+ 24. Kd2 Nc4+ 25. Kc1 Qh4 26. Kc2 Qf2 27. b3 Ne3+ 28. Kd2 Nd5 29. Kd1 Nxf4 0-1
