{Today we will see a victory of one of the best Argentine player, four-time
national champion, GM Ruben Felgaer, who just came back from a brilliant
performance at the Istanbul Olympiad in Turkey. The difficulties he faces, in
just the second round, attests to how difficult the tournament is. The young
and talented Brazilian WFM, Vanessa Feliciano Ebert, gives Ruben serious
problems as will be seen.} 1. d4 d6 2. e4 Nf6 3. f3 c5 $5 {Seeking to play
complicated systems from the very first moves, this is usual for strong
players in Swiss Opens, since it is necessary to win with both White and Black.
} 4. d5 e6 5. c4 b5 $5 {Playing in the spirit of the Benko and contuing to
provoke complications.} 6. cxb5 exd5 7. exd5 Be7 8. Ne2 $1 {An excellent plan
by Vanessa, the knight will go to c3, leaving the one on b1 to sustain the
position in a3. This is the best way to coordinate the pieces.} O-O 9. Nec3 Bb7
10. Bc4 a6 11. O-O Nfd7 $1 {Well played, deploying the knight to b6 and
leaving the f6 square for the bishop.} 12. Bf4 Nb6 13. Na3 {Completing the
development and upholding the advanced outpost.} Bf6 $6 {An imprecision which
will be convincingly refuted.} (13... axb5 $1 {was correct. At the moment,
White cannot take with the knight, so this gives Black sufficient counterplay
for the pawn with a complicated position.}) 14. Qd3 $1 {Now the bishop on c4
is sufficiently protected and White has a clear advantage.} axb5 15. Naxb5 Nxc4
16. Qxc4 Ba6 17. a4 {On top of the pawn deficit, Black has problems with his
b8-knight. Ruben bravely sacrifices his pawn on d6. From a technical
perspective this decision is debatable, but from a practical point of view it
is vital to obtain counterplay and the final result of the game will end of
rewarding the risk taken.} Nd7 $5 18. Bxd6 Bd4+ 19. Kh1 Nb6 20. Qb3 Bxc3 21.
Bxf8 $6 {White's first mistake.} ({With} 21. Qxc3 $1 {White would maintain a
significant advantage since} Bxb5 $2 {is refuted with} 22. Bxf8 {which allows
the bishop to be recaptured, since Black must defend against the mate threat
on g7.}) 21... Bb4 $1 {Now Black continues worse, but with a sharp and
complicated game.} 22. Bxg7 Kxg7 23. f4 {White loses the thread of the game.} (
23. Rfd1 {was the correct and logical continuation.}) 23... Qd7 24. f5 Kh8 25.
Qg3 f6 26. Nc7 $4 {An unfortunate blunder that loses the game on the spot.} ({
After} 26. d6 {There would be plenty of play ahead.}) 26... Rg8 {with Bxf1 to
follow.} 0-1
