I'm giving you a sneak preview of the match by presenting my annotated 
game against Ariel Aton. This is the only game that I have played in a 
tournament against any of the Aton brothers.

[Event "2005 ASEAN tourney elimination"]
[Site "Gaisano Mall, Bajada, Davao City"]
[Date "2005.??.??"]
[Round "2nd "]
[White " Ariel Niño D. Aton"]
[Black "Atty. Jong Guevarra Jr."]
[Result "1/2-1/2"]
[WhiteELO "1963"]
[BlackELO "1835"]

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 
7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. O-O-O Qb8 !? 

This is the Ukrainian variation of the Sicilian Dragon Yugoslav attack. 
This variation was developed by the Ukrainian GM Leonid Stein, a former 
Soviet champion whose premature death at the age of 38 kept him from 
being among the greatest players of his time. Black's plan is to bring the 
rook to c8 and blast open the queenside. Modern theory holds that it is 
somewhat suspect but it can be used as a deadly weapon against an 
opponent not familiar with the line.  

11. Bb3 Rc8 12. Kb1 a5 13. a4 Nxd4 14. Bxd4 
b5! 15. h4?

This move is somewhat automatic in the Yugoslav attack but surprisingly 
it is the losing move (almost!?) in this game. 15. axb5 or 15. Nd5 is much

 15... bxa4 16. Nxa4 Bxa4 17. Bxa4 Rc4! 

18. Bb3 Rxd4!

This exchange sacrifice paves the way for the dragon bishop to enter the
fray with deadly consequence.

19. Qxd4 a4!

 White is now forced to give up his bishop as there is no defense to black's 
threat of 20... Nxe4! 

20. Bxf7+ Kxf7 21. Qc4+ Kf8 22. e5 Nd7 

In the game IM Bouaziz, Slim vs. IM Levy, David- Siegen Olympiad 1970, 
black played the more accurate 22.... Nh5 and white resigned after a few 
more moves. IM David Levy was the famous author of the Sicilian Dragon
book in the 1970's  and I didn't know that I was playing his moves up to this
point of the game.   

23. f4 a3 24. Qb3 Nc5?! 

Fritz suggest 24... Qc8 instead. The exchange of queens favors white
as it somewhat eases out black's attack against white's castled king. At 
any rate, black is still winning and with correct play should have scored the 
full point. 

25. Qxb8+ Rxb8 26. b3 dxe5 27. fxe5 

27... Bxe5? 

More accurate is 27... a2+ ! 28. Kxa2 Bxe5 29. Kb1 Ra8

28. Ka2 Bb2 29. Rh3 Kg7 30. Re3 e5 31. Rd5 Na6
 32. c3 Rc8 33.Rdxe5 


(33....Rxc3 ! 34. Rxc3 Nb4+! )

34. Rxc3 Rxc3 35. Re7+ Kf6?

( Throwing away the win. 35....Kg8 and white can resign... )

 36. Rxh7 Rg3?

( 36... Nc7 is the only move to maintain the advantage but a win is already 

 37. h5! Nc5 38. hxg6 Kxg639. Rh3 


Ariel Aton: I thought that this game would be a bonus round for me but I was wrong.  I never expected Atty. Guevarra was an expert in Sicilian Dragon and so I bravely challenged his opening repertoire with black.  As a result, he defended all my attacks and found myself struggling to save the game.
