1. Ng2 hxg3+ 2. Kxg3 Ke6 3. Nf4+ Kf5 4. Nxh5 Ke6 5. Nf4+ Kd6 6. Kg4 Bc2 7. Kh5 Bd1 8. Kg6 Bxf3 (8... Ke7) 9. Kxf6 {White first maneuvers the Knight to c5 in order to attack the 'a6' weakness.} Bg4 10. Nd3 Be6 11. Nc5 {Next, White attempts to penetrate the kingside with the king.} Bc8 12. Kf7 {Zugzwang!} Kc6 13. Ke7 Kc7 14. Ke8 {Zugzwang!} Kc6 15. Kd8 Bg4 {White's sucessful (aforementioned) penetration attempt makes a6 no longer defendable, hence, Zugzwang once more.} 16. Nxa6 Kd6 {Black's most prophylactic defence lies in using the Bishop and the King to prevent the white King from penetrating the kingside... obviously (after indepth analysis).} 17. Nc5 Bh5 {Once again, it's best to bloackade the white King thus, forcing White to struggle for his King's freedom.} 18. Nb7+ Kc6 19. Kc8 Bg4+ {This attack on the white King helps White to realize his ultimate dream, hence, the 'cure' is worse than the 'disease'.  (Then again, at this stage, it's almost impossible for Black to move without being in Zugzwang.)} 20. Kb8 Kb6 {Black's King is tied down to the passive defence of both a7 and c7.} 21. Nd6 Be6 22. Nc8+ Kc6 23. Ne7+ {White's plan is now to maneuver the Knight to f4 where it shall both attack the d5 pawn and limit the Bishop's choice of moves: technically Zugzwang (considering Black's, already (exponentially) diminishing options).} Kb6 24. Ng6 Bg4
{A Pavlovian response prepared to meet White's threats.} (24... Bf7 25. Nf4 Bg8 26. Kc8 Kc6 27. Kd8 Kd6 28. Ke8 {And the white King is free.}) 25. Nf4 Bf3 26. Kc8 Kc6 27. Kd8 Kd6 28. Ke8 Bh5+ {The fundamentally placed white Knight renders Black's hopes of 'maintaining the opposition' impossible.  Minus the Knight and the Bishop, the latter would have a shot at a 'threefold rep.'.} 29. Kf8 {Free at last!} Bg4 30.Kg7 {White's next plan is to maneuver the King to f6.  Because of the Knight's rudimentary positioning (unthreatened by Black's Bishop for insance.) Black is helpless.} Bf3 31. Kf6 {Make carefull note of how the white King 'holds the door shut' against Black (in this position) in order to facilitate the next series of combinative Knight maneuvers.} Bd1 {Passive defence; a useless Bishop; 'Zugzwang in the making' once more.} 32. Ng6 Be2 33. Ne7 {The next step is to maneuver the Knight to f5 in order to make e5 accessible.  Here's another 'Chess paradox': the white King and Bishop are working together in perfect harmony to obliterate Black's hopes, eventually. This is one of those 'special cases' (thanks to pawn positioning) where a Knight is stronger than a Bishop in an endgame.} Bf3 34. Nf5+ Kc6 (34... Kd7 35. Ke5 Bh1 36. Nd6 Kc6 37. Nc8) 35. Ke6 (35. Ke5 Kd7 36. Nd6 Kc6 37. Nc8 {Is also good.}) 35... Bg4 36. Ke5 {Due to the Ne7+ threat, either d5 or b5 must fall so Black resigned here.} 1-0
