1. e4 e5 2. Nf3 Nc6 3. Bb5 { Once again we see the Ruy Lopez, discussed in previous games of the tournament. } 3... a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 { We've seen this before. White creates a flight square for the Bishop in case of ...Na5. } 8... O-O 9. d3 { You might think that Maroczy is allowing for the development of his Queenside Bishop, but the real purpose of the pawn move is to clear d2 for the development of the Queenside Knight. } 9... Be6 10. Nbd2 Nh5 ( 10... Bxb3 11. Qxb3 Na5 { Black could try to run the Queen off. } 12. Qd1 c5 { And Black has the standard Ruy Lopez Queenside pawn formation. } ) 11. d4 Bxb3 12. axb3 ( 12. Nxb3 { Overprotecting the d4-pawn might be a bit better. } ) 12... Nf4 13. Nf1 Qc8 14. Ng3 { A very coomon theme in the Ruy Lopez -- the White Queenside Knight moves to the Kingside. } 14... g6 15. d5 Nd8 16. Bxf4 exf4 17. Ne2 { Now two Knights have the potential to move to d4. } 17... g5 { Yates has to defend the pawn, but in doing so has created a weak square on f5. } 18. Nfd4 { Eyeing the hole on f5. } 18... Re8 19. Nf5 { We can easily see the weaknesses in Black's Kingside. } 19... Bf8 { Yates kills two birds with one stone: he prevents the exchange of minor pieces on e7 while simultaneously preventing the annoying check at h6. } 20. Ned4 { The Knights defend each other. } 20... f6 { Creating another weakness at e6, a square which can never again be defended by a pawn. } 21. g3 { Maroczy's intent is to open the h-file. } 21... fxg3 22. hxg3 { Once the White King advances to g2, the h-file becomes a highway for the White heavy pieces leading straight to Black's King. } 22... c5 23. Nf3 Nf7 24. Nh2 { Planning to play Ng4 (under the Queen's protection) to contest Black's planned ...Ne5. } 24... Ra7 { The idea is for the Rook to be able to swing to the Kingside and blunt an attack there. } 25. Qh5 Bg7 26. Ng4 { The walls are closing in on Black as the White pieces move to attacking positions. Will Yates be able to defend? } 26... Qd7 27. Kg2 { Preparing for the Rooks to join the attack. Notice how all of White's pieces will soon be in the attack, while the Black defenders are scattered. } 27... Ne5 28. Nxd6 Rd8 ( 28... Qxd6 29. Qxe8+ Qf8 30. Qe6+ Kh8 31. Qb6 ( 31. Rh1 Nxg4 32. Qxg4 { And White is ahead by the exchange, with a good attack going. } ) ) 29. Nxe5 { Thinning the ranks of the defenders. } 29... fxe5 30. Nf5 Bf6 31. Rh1 { And a Rook enters the attack. } 31... Rf8 32. Qg4 { Making way for the Rook to lead the attack. } 32... Kh8 33. Rh6 a5 { Yates is probably considering ...Ra6, to defend the Bishop and free up the other Rook. } 34. Ne3 Qe8 { Yates prefers to keep as many defenders on the board as he can. } ( 34... Qxg4 35. Nxg4 Bg7 36. Rh5 { And the other Rook enters the attack, with harsh consequences for Black. } ) 35. Rah1 { The second Rook enters the fray. Black's barely holding on -- we can see the consequences of the many pawn pushes Yates made earlier in the game. Most of his half of the board is wide open. } 35... Rff7 36. Qf5 Qf8 37. Ng4 Bd8 { Dead wrong -- this move allows mate in three. But in this position, there really aren't any good moves. Yates' position is so bad now that nothing can save it. His King is under furious attack and the passed d5-pawn is a potential killer. } ( 37... Qg7 38. Nxf6 Qg8 ( 38... Rxf6 39. Rxf6 Qg8 40. Rf8 { And mate is unstoppable; in fact, White has a choice of ways to do it. } 40... Rg7 ( 40... Re7 41. Qf6+ Rg7 42. d6 Qxf8 43. Qxf8+ Rg8 44. Qf6+ Rg7 45. d7 { The pawn advances unhindered due to the pin on the Black Rook. } 45... h5 46. Rxh5+ Kg8 47. d8=Q# ) 41. Rxg8+ Rxg8 42. Qxh7# ) 39. Rxh7+ ( 39. Nxg8 Rxf5 40. exf5 Kxg8 41. Rxh7 Rxh7 42. Rxh7 Kxh7 ( 42... Kf8 { Black is lost materially. } ) 43. d6 { The pawn is unstoppable. } ) 39... Rxh7 40. Nxg8 Rxh1 41. Qxe5+ Rg7 42. Nf6 ) 38. Rxh7+ Kg8 39. Qg6+ ( 39. Rh8+ Kg7 40.
