1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nf3 e6 5. Be2 Ne7 6. 0-0 h6 7. Nbd2 Nd7 8. Nb3 g5 9. Ne1 Bg7 10. f4 gxf4? 10. ... Qc7 11. Nd3 b6 is, by transposition, a sounder form of Black’s line of defence; for example: 12. Be3 c5 13. dxc5 gxf4 14. cxb6 axb6 15. Bxf4 Ng6 16. Bg3 0-0 17. Nd4 Be4 18. c3 Ndxe5 19. Nf2 Qd8 20.
