{Game against Ben Silva, a relatively late bloomer in chess, but very tricky.
The only issue with him is his tendancy to be impatient at times. He usually
wins games against me in blitz, but in longer time controls, it's important to
have a good pace.} 1. d4 c5 2. d5 Nf6 3. c4 b5 $5 {The Benko Gambit. It is
still a respected defense and new ideas are evolving all the time. It is a
favorite of many top players.} 4. cxb5 a6 5. bxa6 g6 6. Nc3 Bxa6 7. e4 {One of
the more practical lines.} Bxf1 8. Kxf1 d6 9. g3 (9. g4 $5 {was a line that
was considered an Anti-Benko system that Yasser Seirawan used successfully a
couple of times.} Qc8 10. h3 Bg7 11. Kg2 O-O 12. Nge2 Na6 13. Be3 Qb7 14. Qd2

takes an interesting turn after my next move... which was not good.} Re6 $2 {
not good but probably the most complicated.} (22... Rxd5 23. Nc4 $18 {not good
either.}) (22... Qa8 23. Nxd7 Qxd5+ 24. Kg1 Qxd7 25. Qxe7 Qxe7 26. Rxe7 $18)

two passed pawns. However, the black queen would earn her paycheck in this
game.} (23. b4) 23... Rxe3 24. Nxe3 (24. Rxe3 $142 $1) 24... Qc7 {The knight
is trapped, so white has to playing actively to coordinate pieces.} 25. Red1 $2

White's pieces cannot get coordinated and this spells trouble against a
fleet-footed queen and an exposed white king.} 34. Ne7 Bxb4 {Now I was
