[NM Erwin Retanal(with red t-shirt and hat) pondering his next move against Anthony Mosqueda ].

This game was the biggest upset of the Kadaywan Open and arguably the best game.

Playing the black pieces was NM Elwin Retanal. NM Retanal may be considered as a veteral National Master although only 30 years old and scored upset triumphs over RP's big names the likes of Grand Master Mark Paragua, GM Darwin Laylo, GM elect Ronald Dableo and GM candidate Roland Salvador. He played board 2 for the Philippine team in the World Under-16 Chess Olympian and won a silver medal in the process. He also represented the Philippines in the Asian Junior Chess Championship in Jaipur, India where he finished 10th. He also ruled the 2008 Malaysia Challenger Open in Midvalley, Kuala Lumpur, Malaysia.

Playing the white pieces is 17 years old Anthony Mosqueda of Metro Toril Chess club. He is one of the promising junior players of Davao City and a member of the University of Mindanao (UM) varsity team.

1. e4 e6 2. d3 c5 3. Nf3 Nc6 4. g3 g6

5. Bg2 Bg7 6. O-O Nge7 7. Nbd2 d6

This is the starting position of the King's Indian Attack vs. the Sicilian System. White has 2 main continuations, 8. c3 to prepare the push d4 and 8. Re1 to prepare the push e5. In their book " Modern King's Indian Attack- A complete System for White ", the Authors SM John Hall and Jan R. Cartier prefers the move 8. c3 as it does not only prepare the push d4 but it also limit the scope of Black's dark colored bishop.


G.M Vassily Smyslov essayed the mainline 8. c3 against G.M Mikhail M. Botvinnik in the 23rd game of their 1954 World Championship match held at Vienna, Austria. The game continued 8.c3 0-0 ( by transposition)9.a4 f5 10.Qb3 d5 11.exd5 exd5 12.Re1 f4 13.Nf1 Bg4 14.gxf4 Bxf3 15.Bxf3 Kh8 16.Bd2 Bh6 17.Re6 Bxf4 18.Rae1 Bxd2 19.Nxd2 Nf5 20.Bg2 Nh4 21. Qxd5 Nxg2 22.Qxg2 Qxd3 23.Ne4 Rf5 24.Nd6 Rf3 25.Nxb7 Raf8 26.Nxc5 Qf5 27.Re8 Kg8 28.Rxf8+ 1-0

The move 8. Nb3 in preparation for the pawn push c3-d4 was played a number of times in the 1960's by GM Georgi P. Tringov of Bulgaria and he was quite successful with this line.

8...a5 9. a4 O-O 10. c3 e5

11. d4 b6 12. Be3 Qc7 13. Qd2 Rd8?

I would say that this move started Black's downfall. The rook is needed to defend BLack's kingside and to support the counter- thrust f5. Much better is 13...Ra7 to avoid White's menacing Bishop at g2. The rook can then be transferred to the kingside to further defend Black's King and to support its counter-attack.

14. d5! Nb8 15. Bh6 Bh8 16. Ng5!

Suddenly White's threat of a kingside attack with 17.f4 seems unstoppable as Black's kingside is inadequately protected.

16...Bg7? 17. Bxg7 Kxg7 18. f4 f6 19. fxe5!


If 19...fxg5 20.e6! And Black is in a virtual zugzwang.

Position after 19...dxe5

20. Rxf6!!

This rook sacrifice delivers the final blow against Black's position. The rest is a matter of technique, as the masters would often say.

20...Kxf6 21.Rf1+ Kg7 22. Rf7+ Kg8 23. Qf2 Bf5 24. exf5 Qd6

25. fxg6 Nxg6 26. Ne4 Qf8 27.Rxf8+ Rxf8 28. Nf6+ Kh8 29. Qf5 Ra7

30. Qe6 Raf7 31. Ne4 Nd7 32. Nbd2 Re7 33.Qc6 Ref7 34. Nf3 Nf6

35. Nfg5 Nxe4 36. Nxf7+ Rxf7 37. Bxe4 1-0

Final position
