The tournament used the Scheveningen system which allows each player on one team to play each player on the opposing team. Playing against Grandmasters gave IM Julio Catalino Sadorra ( Ino to friends) and the rest of his IM teammates the much needed chance to achieve GM norms although at the end of the tourney only Ino Sadorra was able to achieve this feat thereby completing his GM norm requirement. He just needs to up his ELO rating to 2500 to be officially awarded the GM title.

The tournament was won by GM Valentin Iotov with 8 pts in 12 rounds. Sadorra lead his UT Dallas Team with 7.5 pts with a TPR of 2645 good enough for 2nd place. However, his team lost to the all GM team 29.5-42.5. Overall, Sadorra scored 4 wins 6 draws and 1 loss. He won against GMs Robson, Panchanathan, Bojkov and Shabalov and suffered his only loss at the hands of GM Robson in their return match when he walked into a prepared line of the French Winawer.

1.Nf3 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.d4 O-O 6.Be2 e5 7.d5

The immediate closing of the centre with 7. d5 is known as the
Petrosian system, after the Armenian World Champion who did much
to develop and popularise the move, especially in conjunction with
8 Bg5, pinning the black knight. (Raymond Keene, Byron Jacobs The
Complete Kings Indian)

The line involves a complex maneuvering game which is a wise choice
against GM Robson who is known as an attacking player.

a5 8.Bg5 h6 9.Bh4 Na6 10.Nd2 c6 11.O-O Bd7 12.Kh1 Qe8

13.Nb3 cxd5?

Black's last move was the cause of his problem for the rest of the
game. Better is 13...g5 14.Bg3 a4 15. Nd2 a3! 16. bxa3 Nc5 =

14.Bxf6 !

The reason why 13...g5 was in order. By this intermediate move
White is able to occupy the critical d5 square.

Bxf6 15.Nxd5 Bd8 16.Nxa5! Nc5

16...Bxa5 losses the Queen because of 17.Nf6 +

17.b4 Rxa5?

True to form, White undertakes a quality sacrifice in a hope to
obtain counter-play. However, White's material advantage and
more active pieces highlighted by his dominating knight at d5
offers black no hope at all. The rest is a matter of technique as
the master would often say.

18.bxa5 Nxe4 19.Bf3 Ba4 20.Qc1 Ng5 21.Bd1 Bc6 22.h4 Ne4

23.Bf3 Bxd5 24.cxd5 Nc5 25.Qxh6 Qe7 26.g3 Bxa5 27.Kg2 e4

28.Bg4 Bc3 29.Rac1 Bg7 30.Qg5 Qxg5 31.hxg5 Re8 32.Rfd1 Kf8

33.Rb1 Ke7 34.Rdc1 Rb8 35.a4 Kd8 36.a5 Kc7 37.Rb4 Re8

38.Rb6 Be5 39.Rb4 Bg7 40.Rh1 Bc3 41.Rb5 Rf8 42.Rh7 Kd8

43.Rh1 Bd2 44.Rhb1 Kc7 45.a6!

IM Sadorra proves that he is equal to the task. This brilliant move
finally shatter black's defense.


If 45... bxa6 46. Rb6! with a clear win for White.

46.axb7 Rxb7 47.Rxb7 Nxb7 48.Bd7! Nc5 49.Be8 Nd3

50.Bxf7 Ne5 51.Be6 e3 52.f4 e2 53.Kf2 e1Q 54.Rxe1 Nd3

55.Ke2 Bxe1 56.Kxd3 Kd8 57.Bf7 Bxg3 58.Ke4 Be1 59.Bxg6 Bd2

60.Kf3 Ke7 61.Kg4 Kf8 62.f5 Kg7 63.Bh5 Bc3 64.f6 Kf8

65.Kf5 Ba5 66.Ke6 1-0

Final position.
