1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 6. Nxc6 ( 6. Ndb5 d6 7. Bf4 e5 8. Bg5 { was at one time considered the best way to approach this position } ) 6... dxc6 { Offering a queen trade is unusual and I'm not so sure White should trade. But, it does cost Black castling priviliges and White has a lead in development, so it can't be terrible for White. The only question is whether a lead in development can be dangerous to Black if there aren't enough pawns to smother him or enough open lines to use a lead in development to good advantage. } ( 6... bxc6 7. e5 Nd5 { is probably the most common way to play this } ) 7. Qxd8+ ( 7. Qf3 $5 ) 7... Kxd8 8. Bf4 { This prevents Black from developing ...Bf8-d6 where it would threaten Ph2 and prevent e4-e5. It also prevents ...Kd8-c7, which would help Black to connect his rooks on the back rank. } 8... Bb4 ( 8... Bc5 ) 9. O-O-O+ Ke7 10. f3 Rd8 ( 10... Nh5 { Black needs to challenge White's control of d6. } ) 11. Be2 { White does her best to maintain perfect control of the d-file and to restrain Black from developing. In such a position every extra move White has to build an offense is crucial. Also, there aren't any seriously weak spots in White's position, so when Black gets developed he still won't have any immediate threats. } 11... Bd7 ( 11... h6 12. h4 Nh5 13. Bh2 g5 $4 { Expanding on the king-side can't work when White has more force there. Black neeeds more developed pieces before beginning something like this. } 14. Rxd8 Kxd8 15. hxg5 hxg5 16. Be5 $16 ) 12. a3 ( 12. Rd3 { intending Nc3-d1-e3-c4 would be interesting } ) 12... Bxc3 $6 ( 12... Ba5 { I don't see any major gain from giving the bishop for Nc3. Does Black think the weakened pawns could be threatened? } ) 13. Bd6+ Ke8 14. bxc3 { Now White has a chance to use c3-c4 to control d5 and e4-e5 to chase Nf6 while creating a bind on Black, so that Bd7 and the rooks can't become active. } 14... b6 15. g4 { threatening g4-g5; another way of chasing Nf6 } ( 15. c4 b5 16. e5 Ng8 17. Rd4 ) 15... c5 { Black steadfastly continues the plan to develop Bd7 and clear the d-file for his rooks. Apparently he wanted to play ...b6 and ...c5, so that when White played 12. a3 he couldn't see any good way to play Bb4 without it becoming trapped, so he traded it for Nc3. } 16. Bc7 Rdc8 17. Be5 { Just a small tactical point: now Black can't avoid a weakened king-side because ...Ke7 can't defend both Bd7 and Nf6. Bxf6 would have to be met by ...gxf6. } 17... Bc6 18. g5 Nh5 19. f4 g6 20. Rd6 { This is an interesting tactical attempt to avoid having to defend Pe4 and it had to have been in mind before she played f3-f4. } 20... Ke7 ( 20... Bxe4 21. Bb5+ Kf8 22. Rhd1 { and White takes the seventh rank (d7) with a rook! } 22... a6 23. Be2 Ng7 { and White can regain the pawn by Rxb6 or take the seventh rank. Which is better? } 24. Rxb6 { and Pa6 is already a target! } ) 21. Ba6 Bxe4 22. Rhd1 $16 Bc6 ( 22... Rc7 23. R6d2 $16 { wins material } ( 23. Rxe6+ $6 fxe6 24. Bxc7 Rf8 ( 24... Bc6 25. Rd6 ) 25. Bb5 ) ) ( 22... Rd8 $4 23. Rxd8 Rxd8 24. Bf6+ Nxf6 25. gxf6+ $18 ) 23. Bb7 { a third nifty tactic to force events. Getting rid of Bc6, so White can invade the seventh rank is more important than winning the exchange by Bxc8. } 23... Be8 24. c4 Ba4 25. R6d3 { Apparently White needs to find (or create) another weak spot in Black's defenses, so it's not so easy for Black to defend. } 25... Bc6 $2 ( 25... Be8 26. Bd6+ Kd7 27. Bxa8 Rxa8 28. Bxc5+ Kc6 29. Be3 $16 ) ( 25... f6 26. Bd6+ Kf7 27. Bxa8 Rxa8 $14 ) 26. Bxc6 Rxc6 27. Rd7+ Ke8 28. Bf6 { threatening checkmate by Rd7-d8+ } 28... Rcc8 29. Re7+ { White doubles rooks on the seventh rank because of this check. Black can't oppose rooks on the d-file. } 29... Kf8 30. Rdd7 $18 { With both White rooks on the seventh rank Black is probably wishing he'd found some other move than 25...Bc6. } 30... Kg8 31. Rxf7 { White's plan is Rf7xh7-h8# } 31... Rf8 ( 31... Nxf6 32. gxf6 Rd8 33. Rg7+ Kf8 34. Rdf7+ Ke8 35. Re7+ Kf8 36. Rxh7 Kg8 37. Reg7+ Kf8 38. Rh8# ) 32. Rxh7 { If 32...Nxf6 33. Rdg7# If 32...Rxf6 33. gxf6 Nxf6 34. Rdg7+ Kf8 35. Rf7+ Kg8 (else Nf6 is lost) 36. Rhg7+ Kh8 37. Rxg6 and Black's position is crumbling. } 1-0
