Muhammad Nor Yahya vs Eric Cheah
National Selection, 1985-86?

1. c4 e5 2. Nc3 g6 3. Nf3 Bg7 4. d4 exd4 5. Nxd4 Nc6 6. e3 Nge7 7. Be2 O-O 8. O-O d6 9. Kh1 Bd7 10. Nc2 Be6 11. Nd5 Qd7 12. Rb1 Rad8 13. b3 h5 14. Bb2 Ne5 15. f4 Ng4 16. Bxg7 Kxg7 17. h3 Nh6  Bxd5 18. hxg4 Bc6 19. f5 gxf5 20. gxh5 Qe6 21. Bf3 Rh8 22. Kg1 Qe5 23. Bxc6 Nxc6 24. Qf3 Ne7 25. Nb4 Qe4 26. Qxe4 fxe4 27. g4 18. Kh2 c6?? The decisive blunder. Black should cover the d4 square with  18... c5 

19. Nf6!! 19...Qc8 of course black can`t take the knight with 19... Kxf6?? because of the mate in 2 after 20. Qd4+ Kf5 21. e4# (21. Bd3#) 

20. Qd4! Nhf5 of course it`s to late now for 20...c5 because of mate after 21.Nxh5+ (21.Nxe8+ also win) 21...Kh7 or 21....Kg8 both being mate with 22.Qg7++   

21. Qc3 Rh8? black can actually prolong the game with   21... d5 22. Nxh5+ Kh6 23. Nf6 but it`s clear that white is winning  

22. e4 1-0 Black knight on f5 will die because if 22....Nh6 then it`s mate in 2 after  23.Nxh5+ Kf8 24.Qg7+ Ke8 25.Nf6++ checkmate.
