喬恩·斯皮爾曼–對–麥克·巴斯曼, 英國國際象棋錦標賽(British Chess Championship) 1984年:
1. e4 e6 2. Nc3 b6 3. d4 Bb7 如要移調到較順手的位置可經由 1.e4 b6 2.d4 Bb7 3.Nc3 e6. 4. Bd3 Nf6 5. Nge2 c5 6. d5! a6 6...exd5 7.exd5 Nxd5 8.Nxd5 Bxd5 9.Nf4 Bc6 (9...Be6? 10.Be4 wins; 9...Qe7+!?)[1] 10.Bc4! "給白方強烈的壓力".[2] 7. a4 exd5 8. exd5 Nxd5 9. Nxd5 Bxd5 10. Nf4 Be6 11. Be4 Ra7 12. 0-0 Be7 約翰·L.·沃森及埃里克·席勒也給出的意見是 12...g6 13.a5! 之後有利於白方是 13...bxa5 14.Bd2 or 13...b5 14.Be3 d6 15.b4 Be7 16.Nxe6 fxe6 17.Qg4 Qc8 18.bxc5 dxc5 19.Bh6, 有意向於 Rad1，Rfe1 及 h4-h5 "只為一個棋子受到極大的壓力"。[3] 13. Ra3 0-0 14. Rg3 f5 15. Bd5 Rf6? 較好的步驟是 15...Bxd5!? 16.Qxd5+ Rf7 17.Nh5 會給予一強大的攻擊力。[1] 16. Re1 Bxd5 17. Qxd5+ Rf7 18. Nh5 g6 19. Bh6 Nc6 20. Rge3 1–0[4] (參見附圖) 白方威脅 21.Nf6+! Bxf6 (21...Kh8 22.Qxf7) 22.Re8+. On 20...gxh5, 21.Rg3+ 贏; 20...Bf8 21.Re8 gxh5 23.Bxf8!; 20...Ra8 21.Rxe7! Nxe7 現在於 22.Rxe7 Qxe7 23.Qxa8+ 或 22.Nf6+ Kh8 23.Qxf7 其中的一個步驟會贏。[1]
